Second generation (2G) wireless data networks in Japan deliver datarates up to 9.6 kbps for upload and up to 29.8 kbps for download. 3DES - Triple Data Encryption Standard 3G - Third generation (3G) wireless networks in Japan deliver datarates on the order of 64 kbps for upload and on the order of 200 kbos for downlad. These higher speeds allow the transmission of video and two-way video telephony. Other data connections, e.g. download of information or JAVA applets, are also several times faster on 3G networks then on older 2G networks. In Japan there are three parallel, independent and competing 3G networks. In U.S, 3G currently (12/03) supports 300 to 500 kilobits per second, with bursts up to 2 mbps. 3GPP - Third Generation Partnership Project (3GPP) is a collaboration agreement that was established in December 1998. The collaboration agreement brings together a number of telecommunications standards bodies which are known as "Organizational Partners". The current Organizational Partners are ARIB, CCSA, ETSI, ATIS, TTA, and TTC. The original scope of 3GPP was to produce globally applicable Technical Specifications and Technical Reports for a 3rd Generation Mobile System based on evolved GSM core networks and the radio access technologies that they support (i.e., Universal Terrestrial Radio Access (UTRA) both Frequency Division Duplex (FDD) and Time Division Duplex (TDD) modes). The scope was subsequently amended to include the maintenance and development of the Global System for Mobile communication (GSM) Technical Specifications and Technical Reports including evolved radio access technologies (e.g. General Packet Radio Service (GPRS) and Enhanced Data rates for GSM Evolution (EDGE)).

Third-Generation Partnership Project 2 is a collaborative effort for Generating 3G specifications for providing high-speed IP-based mobile systems. It was established for developing global specifications for network evolution from ANSI/TIA/EIA-41 to 3G, and global specifications for the radio transmission tehcnologies supported by ANSI/TIA/EIA-41. 3GPP2 is mainly supported in North America, China, Japan and South Korea and continues to play a dominant role in bringing IP technology to these cellular markets. 3GPP2 was born out of the International Telecommunication Union (ITU) International Mobile Telecommunications-2000 (IMT-2000) initiative for providing high-speed data over the wireless network. Although discussions did take place between ETSI and the ANSI-41 community to consolidate collaboration efforts for 3G, in the end it was deemed appropriate to establish 3GPP2 as a parallel partnership project.

Click here for more 480I information 4G - At present the download speed for imode data is limited to 9.6 kbit/sec which is about 6 times slower than an ISDN fixed line connection. With 504i handsets the download data rate was increased 3-fold to 28.8kbps. However, in actual use the data rates are usually slower, especially in crowded areas, or when the network is "congested". For third generation mobile (3G) data rates are 384 kbps (download) maximum, typically around 200kbps, and 64kbps upload since spring 2001. Fourth generation (4G) mobile communications will have higher data transmission rates than 3G. 4G mobile data transmission rates are planned to be up to 20 megabits per second.

[common; From Swift's "Gulliver's Travels" via the famous paper "On Holy Wars and a Plea for Peace" by Danny Cohen, USC/ISI IEN 137, dated April 1, 1980] 1. Describes a computer architecture in which, within a given multi-byte numeric representation, the most significant byte has the lowest address (the word is stored `big-end-first'). Most processors, including the IBM 370 family, the PDP-10, the Motorola microprocessor families, and most of the various RISC designs are big-endian. Big-endian byte order is also sometimes called `network order'. See little-endian, middle-endian, NUXI problem, swab. 2. An Internet address <../i/Internet_address.html> the wrong way round. Most of the world follows the Internet standard and writes email addresses starting with the name of the computer and ending up with the name of the country. In the U.K. the Joint Networking Team had decided to do it the other way round before the Internet domain standard was established. Most gateway sites have ad-hockery <../a/ad-hockery.html> in their mailers to handle this, but can still be confused. In particular, the address me@uk.ac.bris.pys.as could be interpreted in JANET's big-endian way as one in the U.K. (domain uk) or in the standard little-endian way as one in the domain as (American Samoa) on the opposite side of the world.

BIRT - Build Integration Release Testing BIS - Boot Integrity Service BIST - Built-In Self Test (hardware feature) bit - n. [from the mainstream meaning and `Binary digIT'] 1. [techspeak] The unit of information; the amount of information obtained by asking a yes-or-no question for which the two outcomes are equally probable. 2. [techspeak] A computational quantity that can take on one of two values, such as true and false or 0 and 1. 3. A mental flag: a reminder that something should be done eventually. "I have a bit set for you." (I haven't seen you for a while, and I'm supposed to tell or ask you something.) 4. More generally, a (possibly incorrect) mental state of belief. "I have a bit set that says that you were the last guy to hack on EMACS." (Meaning "I think you were the last guy to hack on EMACS, and what I am about to say is predicated on this, so please stop me if this isn't true.") "I just need one bit from you" is a polite way of indicating that you intend only a short interruption for a question that can presumably be answered yes or no. A bit is said to be `set' if its value is true or 1, and `reset' or `clear' if its value is false or 0. One speaks of setting and clearing bits. To toggle or `invert' a bit is to change it, either from 0 to 1 or from 1 to 0. See also flag, trit, mode bit. The term `bit' first appeared in print in the computer-science sense in a 1948 paper by information theorist Claude Shannon, and was there credited to the early computer scientist John Tukey (who also seems to have coined the term `software'). Tukey records that `bit' evolved over a lunch table as a handier alternative to `bigit' or `binit', at a conference in the winter of 1943-44. bitblit - (BIT BLock Transfer) In computer graphics, a hardware feature that moves a rectangular block of bits from main memory into display memory. It speeds the display of moving objects (animation, scrolling) on screen. A hardware bitblt provides fastest speed, but bitblts are also implemented in software even in non-graphics systems. For example, text scrolls faster when it is copied as a contiguous block (bitblt) to the next part of the window rather than processing every character on every line. See stretch blt.

ETL - extract, transform, load = In managing databases, extract, transform, load (ETL) refers to three separate functions combined into a single programming tool. First, the extract function reads data from a specified source database and extracts a desired subset of data. Next, the transform function works with the acquired data - using rules or lookup tables, or creating Combinations with other data - to Convert it to the desired state. Finally, the load function is used to write the resulting data(either all of the subset or just the changes) to a target database, which may or may not previously exist. ETL can be used to acquire a temporary subset of data for reports or other purposes, or a more permanent data set may be acquired for other purposes such as: the population of a data mart or data warehouse; conversion from one database type to another; and the migration of data from one database or platform to another.

FC-AL - same as FCAL FCAPS - ISO fault-management, configuration, accounting, performance, and security) is an acronym for a categorical model of the working objectives of network management. There are five levels called: the fault-management level (F), the configuration level (C), the accounting level (A), the performance level (P), and the security level (S). At the F level, network problems are found and corrected. Potential future problems are identified, and steps are taken to prevent them from occurring or recurring. In this way, the network is kept operational, and downtime is minimized. At the C level, network operation is monitored and controlled. Hardware and programming changes, including the addition of new equipment and programs, modification of existing systems, and removal of obsolete systems and programs, are coordinated. An inventory of equipment and programs is kept and updated regularly. At the A level, which might also be called the allocation level, is devoted to distributing resources optimally and fairly among network subscribers. This makes the most effective use of the systems available, minimizing the cost of operation. This level is also responsible for ensuring that users are billed appropriately. The P level is involved with managing the overall performance of the network. Throughput is maximized, bottlenecks are avoided, and potential problems are identified. A major part of the effort is to identify which improvements will yield the greatest overall performance enhancement. At the S level, the network is protected against hackers, unauthorized users, and physical or electronic sabotage. Confidentiality of user information is maintained where necessary or warranted. The security systems also allow network administrators to control what each individual authorized user can (and cannot) do with the system.

See Embedded / Firmware for more information FWB - Fixed Wireless Broadband FWH - firmware hub (a chip/hub used to store the BIOS codes) (Courtesy of electro-tech-online.com and phil7890 FWH are SPI are typically thought of as chips (some insist it's a hub). This is used to store the BIOS firmware/codes. For example, the Phoenix/Award BIOS or AMI BIOS (or other equivalent BIOS) codes are stored in this FWH or SPI serial chip. The brand on the FWH is typically SST, Atmel, Intel or Winbond. However with the Winbond brand we'll have to be careful as they make many other types of chips too (not just memory chips - but their other chips typically have a lot of pins, ie. more than 32 for a FWH). The FWH is usually a 32-pin PLCC chip. Most/some of the time it'll be sitting in a socket so that it's removable if anybody wants to do this. It'll typically have a 29-something part number. (from LPC, FWH And SPI Used In Bios Rom?) If we can't find a 32-pin FWH (PLCC chip with or without socket), then we'll have to look for an 8-pin chip of those similar brands. The part number is typically 25-something or 45-something, etc. The SPI chip is normally 8-pin, and it is sometimes found on recent motherboards using the Intel 965 or newer chipsets. It is normally soldered down - without a socket. The FWH is usually a 32-pin PLCC chip. 1. Yes we can regard the 32-pin PLCC as a BIOS ROM chip but this as long as it's a memory/flash/EE type of chip. 2a. It's usually the south bridge chip (I/O controller hub) where the BIOS chip (LPC/FWH/SPI) connects to, ie. it's like a leaf of its own and hanging off this south bridge branch. From the south bridge chip, various other items connect to/out from here. 2b. As for the LPC bus itself, some items such as the BIOS chip, Super I/O (multifunction) chip, optional TPM/security chip, and other ~low-speed/ bandwidth chips can be found here. 3a. We normally don't hear anything called HPC (high pin count) on a motherboard but there are various chips with lots of pins. There's HPC for a high-performance something-else though. 3b. It's usually in the microcontroller world (for example, the PIC stuff) where we find this HPC term. It's because the PIC originally came with a few pins and over the years they added many more general-purpose I/O pins. - Courtesy of: phil7890 FWSM - firewall services module (Cisco) G.SHDSL - Also known as G.991.2, G.SHDSL is an international standard for symmetric DSL developed by the ITU.

GA - General Availability GAMP - Good Automated Manufacturing Practices gang-of-four - Erich Gamma, Richard Helm, Ralph Johnson, John Vlissides Gang Trespass - Source LUs and their associated Snapshot LUs must be owned by the same SP. If a source LU is trespassed, any associated Snapshot LU must also implicitly be trespassed. The same is also true if the Snapshot LU is trespassed. A design of how Gang Trespass will be implemented was agreed to in a meeting with Dave Harvey and Jim Cook in SOBO. Details of this implementation will be released by them and implemented in time for SnapView Phase 2 qualification Gantt Chart - A Gantt chart is a powerful and preferred visual reporting device used for conveying a project's schedule. A typical Gantt chart graphically displays the work breakdown, total duration needed to complete tasks, as well as %completion. The Gantt chart itself will not display level of effort, and is not an effective planning tool on its own. Today, Gantt Charts may be integrated with other spreadsheet-type reporting devices that convey additional information related to project planning. Furthermore, Gantt Charts are often enhanced with functionality that includes the identification of relationships between tasks, and the ability to dynamically change task attributes. gap analysis - something in QA coverage ?? perhaps, analysis of missing coverage? GARP - Generic Attribute Registration Protocol. GARP was originally designed to to facility multicast filtering at the MAC layer. GARP was generalized and two trivial applications were designed on top of GARP: 1] the GARP VLAN Registration Protocol (GVRP), and 2] the GARP Multicast Registration protocol (GMRP). The only difference: GMRP manipulates 48-bit multicast MAC addresses, while GVRP handles 12-bit VLAN IDs. gas - GNU Assembler gateway - A device that connects dissimilar networks.

[Doug Hoffman] Gray Box Testing - Examines the activity of back-end components during test case execution. Two types of problems that can be encountered during gray-box testing are: 1] A component encounters a failure of some kind, causing the operation to be aborted. The user interface will typically indicate that an error has occurred. 2] The test executes in full, but the content of the results is incorrect. Somewhere in the system, a component processed data incorrectly, causing the error in the results. [Elfriede Dustin.

GVRP - the GARP VLAN Registration Protocol gw - GateWay (router) GWT - Google Web Toolkit H.225 - ITU-T : Series H H.225.0 v2 is a standard which covers narrow-band visual telephone services defined in H.200/AV.120-Series Recommendations. It specifically deals with those situations where the transmission path includes one or more packet based networks, each of which is configured and managed to provide a non-guaranteed Quality of Service (QoS) which is not equivalent to that of N-ISDN such that additional protection or recovery mechanisms beyond those mandated by Rec. H.320 is necessary in the terminals. H.225.0 describes how audio, video, data, and control information on a packet based network can be managed to provide conversational services in H.323 equipment. The structure of H.225 follows the Q.931 standard H.235 - H.235 provides enhancements within the framework of the H.3xx-Series Recommendations to incorporate security services such as Authentication and Privacy (data encryption). H.235 should work with other H series protocols that utilize H.245 as their control protocol. All H.235 messages are encrypted as in ASN.1. H.245 - H.245 is line transmission of non-telephone signals. It includes receiving and transmitting capabilities as well as mode preference from the receiving end, logical channel signalling, and Control and Indication. Acknowledged signalling procedures are specified to ensure reliable audiovisual and data communication. H.245 messages are in ASN.1 syntax. They consist of an exchange of messages. MultimediaSystemControlMessage message types can be defined as request, response, command and indication messages. The following additional message sets are available: Master Slave Determination messages Terminal capability messages Logical channel signalling messages Multiplex Table signalling messages Request Multiplex Table signalling messages Request Mode messages Round Trip Delay messages Maintenance Loop messages Communication Mode Messages Conference Request and Response Messages TerminalID Commands and Indications H.248 - H.248 - a Control Protocol Stack coupling. See also MGCP H.261 - H.261 describes a video stream for transport using the real-time transport protocol, RTP, with any of the underlying protocols that carry RTP. H.263 - H.263 specifies the payload format for encapsulating an H.263 bitstream in the Real-Time Transport Protocol (RTP). Three modes are defined for the H.263 payload header. An RTP packet can use one of the three modes for H.263 video streams depending on the desired network packet size and H.263 encoding options employed. The shortest H.263 payload header (mode A) supports fragmentation at Group of Block (GOB) boundaries. The long H.263 payload headers (modes B and C) support fragmentation at Macroblock (MB) boundaries. For each RTP packet, the RTP fixed header is followed by the H.263 payload header, which is followed by the standard H.263 compressed bitstream. The size of the H.263 payload header is variable depending on the modes. H.323 - H.323 Protocol The H.323 standard provides a foundation for audio, video, and data communications across IP-based networks, including the Internet. H.323 is an umbrella recommendation from the International Telecommunications Union (ITU) that sets standards for multimedia communications over Local Area Networks (LANs) that do not provide a guaranteed Quality of Service (QoS). H.323 is generally modeled after PRI/ISDN and H.320 signaling models in some places with some additional innovations (if you can call them that) thrown in. H.450.1 - The H.45o series defines Supplementary Services for H.323, namely Call Transfer and Call Diversion. The H.450.1 protocol deals with the procedures and signalling protocol between H.323 entities for the control of supplementary services. This signalling protocol is common to all H.323 supplementary services. The protocol is derived from the generic functional protocol specified in ISO/IEC 11582 for Private Integrated Services Networks (PISN). The H.450 protocol is used to exchange signalling information to control supplementary services over a LAN. It works together with the H.225 protocol. This protocol has no header as all messages are in text, in ASN.1 format. H.450.2 - This is a Call Transfer supplementary service for H.323. The H.450.2 protocol describes the procedures and signalling protocol for the call transfer supplementary service in H.323 networks. This supplementary service allows the served user A to transform an existing call (from user A to B) to a new call between user B and a third user C selected by A. User A may or may not have a call established with the third user prior to the call transfer. This is based on H.450.1 This protocol has no header as all messages are in text, in ASN.1 format. H.450.3 - The H.450.3 is a call diversion supplementary service for H.323. It describes the procedures and signalling protocol for the call diversion supplementary service in H.323 networks. This includes the services Call Forwarding Unconditional (SS-CFU), Call Forwarding Busy (SS-CFB), Call Forwarding No Reply (SS-CFNR) and Call Deflection (SS-CD). These are all supplementary services, which apply during call establishment, providing a diversion of an incoming call to another destination endpoint. This is based on H.450.1 This protocol has no header as all messages are in text, in ASN.1 format. H.264 - H.264 flavor of MPEG-4 (also known as MPEG-4 Part 10 or Advanced Video Coding). This feature is strategically significant because H.264/AVC has been chosen to be part of the next-generation Blu-Ray and HD-DVD blue-laser optical-disc specifications.

HyperTransport LOST - Everyone is using PCIe. The current (8/2001) HyperTransport spec calls for an aggregate bandwidth of 6.4 GB per second in a 16-bit configuration, and 12.8 Gb/sec in a 32-bit configuration. In contrast, 32-bit PCI starts at less than 133 MB/second, and scales to only 533 MB/sec at 64-bit configurations HyperTransport is 24 times faster than PCI, out of the gate. HyperTransport is software compatible with PCI - vendors will not have to rewrite their PCI device drivers. Hypothesis Testing - Hypothesis testing refers to the process of using statistical analysis to determine if the observed differences between two or more samples are due to random chance (as stated in the null hypothesis) or to true differences in the samples (as stated in the alternate hypothesis). A null hypothesis (H0) is a stated assumption that there is no difference in parameters (mean, variance, DPMO) for two or more populations. The alternate hypothesis (Ha) is a statement that the observed difference or relationship between two populations is real and not the result of chance or an error in sampling. Hypothesis testing is the process of using a variety of statistical tools to analyze data and, ultimately, to accept or reject the null hypothesis. From a practical point of view, finding statistical evidence that the null hypothesis is false allows you to reject the null hypothesis and accept the alternate hypothesis. I&C - instrumentation and control I&KM - Information and knowledge management (I&KM) i-mode - I_T - Initiator_Target I_T_L - Initiator_Target_LUN I2C (bus, controller) - Inter IC Communications bus/protocol/controller.

ICAP is, in essence, a lightweight protocol for executing a "remote procedure call" on HTTP messages. It allows ICAP clients to pass HTTP messages to ICAP servers for some sort of transformation or other processing ("adaptation"). The server executes its transformation service on messages and sends back responses to the client, usually with modified messages. Typically, the adapted messages are either HTTP requests or HTTP responses.

ICF - Internet Connection Firewall - Microsoft has recognized the importance of personal firewalls too. Window XP and Windows Server 2003 come with a rudimentary firewall called Internet Connection Firewall. ICF isn't a very useful firewall, although users running it are better off than users without it. The upcoming Windows XP Service Pack 2 will upgrade ICF and rename it "Windows Firewall." PC Magazine recently took a good hard look at it. Windows Firewall won't have all the features of third-party personal firewalls—for instance, it won't have tight control over programs on your system making outbound communications—but it will be turned on by default and will offer much more control over the security of your system than exists today in Windows out of the box.

Systems Integration - Wikipedi Integration Patterns (Book) - Microsoft Integration Testing - testing of combined parts of an application to determine if they function together correctly. The 'parts' can be code modules, individual applications, client and server applications on a network, etc. This type of testing is especially relevant to client/server and distributed systems. Testing conducted after unit and feature testing. The intent is to expose faults in the interactions between software modules and functions. Either top-down or bottom-up approaches can be used. A bottom-up method is preferred, since it leads to earlier unit testing (step-level integration) This method is contrary to the big-band approach where all source modules are combined and tested in one step. The big-band approach to integration should be discouraged. Intel-VT - Intel Virtualization Technology (for CPUs). More info Interface - An abstract class providing a set of methods for a specific service. For example, the IDisplay interface provides a set of methods for basic display services. Each interface has a unique class identifier (AEECLSID), and the name of each interface begins with the letter “I.” In BREW, all the interfaces are derived from a base level class interface called IBase. IBase consists of two standard methods for incrementing and decrementing the reference count of an object. This reference count mechanism allows an object to be shared by multiple users. Interface Tests - Programs that probide test facilities for external interfaces and function calls. Simulation is often used to test external interfaces that currently may not be available for testing or are difficult to control. For example, hardware resources such as hard disks and memory may be difficult to control. Therefore, simulation can provide the characteristics or behaviors for specific function. interlaced - not all vertical lines of the video picture are displayed at once.

To calculate the mean, add all of the individual data points then divide that figure by the total number of data points. Median - Relating to or constituting the middle value in a distribution. The median is the middle point of a data set; 50% of the values are below this point, and 50% are above this point. Median is the middle value, when all possible values are listed in order. Median is not the same as Average (or Mean). megabyte n. Abbr. MB A unit of computer memory or data storage capacity equal to 1,048,576 bytes. One million bytes. Megaco - The latest call control protocol, Megaco (an evolution of Media Gateway Control), adds to the problem while seeking to reduce the number of protocols in use. ITU designation, H.248 Megaco is essentially quite similar to MGCP from an architectural standpoint and the controller-to-gateway relationship, but Megaco supports a broader range of networks, such as ATM. I can say that Megaco is more closely coupled with media applications than MGCP because the base protocol includes semantics for conferencing. Because of that, MGCP may be a better base for non-media-centric applications, such as MPLS-based session control.

MFTE => frame => physical address translation - fast and easy - one per physical page MG - Media Gateway MGC - Media Gateway Controller MGCF - Media Gateway Control Function MGCP - The Media Gateway Control Protocol, developed by Telcordia and Level 3 Communications, is one of a few proposed control and signal standards to compete with the older H.323 standard for the conversion of audio signals carried on telephone circuits (PSTN ) to data packets carried over the Internet or other packet networks. The reason new standards are being developed is because of the growing popularity of Voice over IP (VoIP ). Regular phones are relatively inexpensive because they don't need to be complex; they are fixed to a specific switch at a central switching location. IP phones and devices, on the other hand, are not fixed to a specific switch, so they must contain processors that enable them to function and be intelligent on their own, independent from a central switching location. This makes the terminal (phone or device) more complex, and therefore, more expensive. The MGCP is meant to simplify standards for this new technology by eliminating the need for complex, processor-intense IP telephony devices, thus simplifying and lowering the cost of these terminals. I can say that Megaco is more closely coupled with media applications than MGCP because the base protocol includes semantics for conferencing. Because of that, MGCP may be a better base for non-media-centric applications, such as MPLS-based session control. JAINTM MGCP 1.0 Specification - Final Release Bellcore (www.bellcore.com) and Level 3 Communications Inc. (www.l3.com) have merged two protocols intended to bridge the gap between circuit-switched and Internet protocol (IP) networks. The resulting protocol is known as Media Gateway Control Protocol, or MGCP, and is a combination of Internet Protocol Device Control (IPDC) and Simple Gateway Control Protocol (SGCP). MGCP enables external control and management of data communication devices, or "media gateways," at the edge of multiservice packet networks by software programs, also known as "call agents" or "media gateway controllers." Media gateways can be voice over IP gateways, voice over asynchronous transfer mode (ATM) gateways, modem banks, cable modems and set-top boxes, soft private branch exchanges (PBXs) and/or cross-connects. Merging IPDC and SGCP (into MGCP) means equipment providers can design to a single spec, so interoperability among a wider range of equipment is possible. But he says that neither SIP nor H.323 were designed to deal with the legacy switched telephone network; whereas MGCP-compliant controllers and gateways will interoperate seamlessly with H.323 and SIP endpoints, as well as with legacy telephones. MGCP Documentation MGCP was originally SGCP, prodcued by Bell and Alcatrel ? MGCP (originally SGCP) was designed to allow Media Gateway Controllers (MGC) to control the Media Gateway (MG) - in effect controlling a switching fabric both on the IP and the TDM domains. MGCP was also found useful with vendors who wanted to simplify Gateways by focusing on either Hardware or Software, but also created political havoc with many major players in the field. At some point in '98 there were no less then 5-candidate protocols all trying to solve the same problem as SGCP/MGCP.

See MMO - Massive Multiplayer On-Line (games, usually) MMR - Manufacturing Readiness Review MMS - Multimedia Messaging Services - Mobile Internet Is Getting Better The newest development in mobile messaging is called Multimedia Messaging Service, or MMS for short. MMS allows mobile phone users to incorporate audio, images, and other rich content with traditional text messages, transforming them into personal collages of vision and sound. Multimedia messaging reshapes the landscape of mobile communication, making it more personal, more versatile, and more expressive than ever before. MMS (Multimedia Messaging Service) is a universally accepted standard that lets users of MMS supportive mobile phones send and receive messages with formatted text, graphics, photo-graphic imagery and audio and video clips. Video sequences, audio clips and high-quality images can be downloaded to the phone from WAP sites, transferred to the phone via an attached accessory, such as a digital camera, or received in an MMS message. MMS messages can be sent either to another MMS-enabled mobile phone or to an e-mail address. Photos, sound and video clips can also be stored in the phone for later use. MMS supports standard image formats such as GIF and JPEG, video formats such as MPEG 4 and audio formats such as MP3 and MIDI. Multimedia messaging is dependent on high transmission speeds, something GPRS and the new high speed 3G technologies can provide. To support the MMS technology, existing GSM networks need an MMS-C (Multimedia Messaging Service Centre). MMS DAVE's MMS INFO mmse - MMS Message Encapsulation MMSC - MMS-C = Multimedia Messaging Service Centre MMUSIC - Multiparty Multimedia Session Control MNC - Multinational corporation = TNC MO - (SMS) Mobile Originating - the ability to send text messages from the phone. Keying messages into the phone is a little arduous as you need to to press several keys per character, but it can be mastered. Some phones allow attachement of external devices, such as QWERTY keyboards. mobile data - wireless data (data sent wirelessly). mobile data terminal - "A mobile data terminal (MDT) is a computerized device used in public transit vehicles, taxicabs, courier vehicles, service trucks" Mobile IP - MobileShop - Generically refers to an application that is used to connect to a carrier’s catalog, review catalogs and applications, and perform over-the-air downloads of applications.

Modal often describes a secondary window that restricts a user's interaction with other windows. mode - The value or item occurring most frequently in a series of observations or statistical data. The most often occurring value in the data set. A data set may contain more than one mode, e.g., if there are exactly 2 values or items that appear in the data the same number of times, we say the data set is bi-modal. mode bit - n. [common] A flag, usually in hardware, that selects between two (usually quite different) modes of operation. The connotations are different from flag bit in that mode bits are mainly written during a boot or set-up phase, are seldom explicitly read, and seldom change over the lifetime of an ordinary program. The classic example was the EBCDIC-vs.-ASCII bit (#12) of the Program Status Word of the IBM 360. Module - In the BREW model, a library or dynamically loaded code block that exposes one or more interfaces. As each interface is associated with an ID, the module can expose these interfaces in a generic manner. This eliminates the need for explicit entry points in modules for each exported interface.

This includes procedures and protocols for the distribution of labels between routers, encapsulations and multicast considerations. The initial goals of the working group have been largely completed. In particular, it has produced a number of RFCs that define the base Label Distribution Protocol (LDP), the basic MPLS architecture and encapsulations, and definitions for how MPLS runs over ATM and Frame Relay links. MPLS Forum The MPLS Forum's first completed implementation agreement provides a standards-based approach for service providers offering voice-over-packet services to interconnect voice media gateways over their MPLS networks.

NAT - NAT (Network Address Translation) is the translation of an Internet Protocol address (IP address) used within one network to a different IP address known within another network. One network is designated the inside network and the other is the outside. Typically, a company maps its local inside network addresses to one or more global outside IP addresses and unmaps the global IP addresses on incoming packets back into local IP addresses. This helps ensure security since each outgoing or incoming request must go through a translation process that also offers the opportunity to qualify or authenticate the request or match it to a previous request. NAT also conserves on the number of global IP addresses that a company needs and it lets the company use a single IP address in its communication with the world.

The Windows NT native disk format. Provides an efficient data storage format, and allows a range of security settings to be applied to individual files and directories. How many characters can a filename have? The maximum number of characters you can use for a filename depends on whether the file is on an NTFS partition or a FAT partition. You can have a 256-character filename on an NTFS partition but only an 11-character filename on an FAT partition (i.e., an 8-character filename with a 3-character extension). The version of FAT that comes with Windows NT 4.0 supports 255-character filenames, unless you turn on Win 3.1. VFAT uses 256-character filenames. NTFS filenames are case sensitive (except during searches), whereas FAT filenames do not retain case. NTFS filenames can contain any characters, including spaces and uppercase, except " * : / \ ? < > |. VFAT filenames must start with a letter or number and can contain any characters except / \ : | ? " ^. How many files can I create on the root of a FAT partition? The root of a FAT drive holds only 512 entries. Remember that long filenames use multiple entries. Thus, creating numerous long filenames on the root of a partition uses space quickly. NTLM - NT LAN Manager authentication.

An object's state consists of its attributes and the attributes' current values. An object's behavior consists of the operations that can be performed on it and the accompanying state changes. An object's identity is what you use to distinguish it from other objects. In contrast, COM objects' behavior is defined by the interfaces it supports. A COM object's state is not explicitly specified, but is implied by its interfaces. A COM object's identity is defined by the ability to use IUnknown::QueryInterface to move between interfaces. object serialization - Serialization lets you store objects and handle them with binary input/output streams.

OPD - Onsite Problem Determination openSUSE - Novell renamed its free Linux OS openSUSE, to differentiate it from Enterprise versions. Click for more information OPES - Open Pluggable Services OpenSSL - Secure Sockets Layer was originally designed and implemented by Netscape in 1995 [Hickman1995]. Since then it has gone through a number of revisions [Freier1996]. It is also adopted by IETF as a standard for transport layer security protocol (TLS) [Dierks1999]. To this day, SSLv2, SSLv3 and TLSv1 are still used and supported by the most current releases of popular browsers. Although SSL is supposed to be layered above TCP, it is implemented as a user level protocol. This works well for delivering web applications for multiple platforms without having to modify the kernel in each case. OpenSSL provides a socket like API for developers. But since it is not a true socket interface, developers are stuck with the added complexity of calling the socket interface in additional to the OpenSSL API.
