A multiaccess key lets the user adapt the key to the particular organism that is being identified and to the circumstances of identification e.g. field or laboratory .

Unreferenced date December 2009 Orphan date December 2009 SMART , Scandinavian MultiAccess Reservations for Travel Agents, is a computerized system for ticket reservation. History It was created in 1979 by Scandinavian Airlines System SAS , Braathens and Swedish Railways . Many travel companies had computerized their systems at the time, and provided terminal interfaces for travel agencies. Each had their own system, often involving widely different codes and procedures. It was cumbersome and expensive for a travel agency to have multiple terminals, each one connected to a different provider. SMART solved this, by providing a single interface over the public data network Datex . It worked by having a Host Interface Processor HIP at each travel company. These would emulate a number of terminals, translate the messages, codes and addresses, wrap them in SMARTs own communications protocol , and provide the interface over Datex to the various travel agencies. There was, of course, functionality to limit access. On the travel agency side, there would be SMART Terminal Equipment STE with the reverse function, emulating a server and providing interfaces for terminals. Now however, a travel agent could easily switch between screens for the different companies. The interfaces were similar to those for direct connections, but provided some standardization for codes to ease the transition between the systems. The STE would also allow printing of documents, tickets, bills and similar, as well as interfacing with the accounting system. SMART could utilize some of Datex extra features like queuing and group numbers, and a logical connection session was not dependent on the physical connection which could go up and down for instance during idle times to save money . Parallel sessions could be held with different or the same provider. SMART spawned off into a company centered in Stockholm ... name to Amadeus Scandinavia .

Multi Carrier Code Division Multiple Access MC CDMA is a multiple access scheme used in OFDM based telecommunication systems, allowing the system to support multiple users at the same time. MC CDMA spreads each user symbol in the frequency domain. That is, each user symbol is carried over multiple parallel subcarriers, but it is phase shifted typically 0 or 180 degrees according to a code value. The code values differ per subcarrier and per user. The receiver combines all subcarrier signals, by weighing these to compensate varying signal strengths and undo the code shift. The receiver can separate signals of different users, because these have different e.g. orthogonal code values. Since each data symbol occupies a much wider bandwidth in hertz than the data rate in bit s , a signal to noise plus interference ratio if defined as signal power divided by total noise plus interference power ... whitepapers whitepaper pdf service4.pdf Multi Carrier Code Division Multiple Access , March ... mcss2007 history.php History of Multi Carrier Code Division Multiple Access MC CDMA and Multi Carrier ... to one or more terminals , MC CDMA typically reduces to Multi Carrier Code Division Multiplexing ... form of multi carrier CDMA , called MC DS CDMA or MC DS CDMA, performs spreading in the time ... and 3. ref http citeseer.ist.psu.edu atarashi02broadband.html Broadband Packet Wireless Access Based ... and frequency spreading Orthogonal Frequency Code Division Multiple Access OFCDMA References references Literature N.

Unreferenced stub auto yes date December 2009 A non broadcast multiple access network NBMA is a computer network to which multiple hosts are attached, but data is transmitted only directly from one computer to another single host over a virtual circuit or across a switched fabric . NBMA networks do support multicast or Broadcasting computing broadcast traffic manually Pseudo broadcasts . Some common examples of nonbroadcast network technologies include Asynchronous Transfer Mode ATM , Frame Relay , X.25 , and home power line networking. Power line networks The ITU T G.hn standard provides a specification for creating a high speed up to 1 Gigabit s local area network using existing home Power line communication power lines , phone lines and Ethernet over coax coaxial cables . Because of multipath propagation , power lines use frequency selective channels. Channel frequency response is different for each pair of transmitter and receiver, so modulation parameters are unique for each transmitter and receiver pair. Since each pair of devices uses a different modulation scheme for communication, other devices may not be able to demodulate the information sent between them. Split horizon route advertisement In NBMA networks a special technique called split horizon route advertisement must be employed by distance vector routing protocol s in order to prevent routing loop s. This family of protocol relies on link layer broadcasting for route advertisement propagation, so when this feature is absent, it has to be emulated with series of unicast transmissions, which may result in receiver node sending a route advertisement back to the node it has just received it from.

Not to be confused with http www.multisourcemfg.com Multisource Manufacturing LLC of Twin Cities , Minnesota MN . Multi source , as it applies to download ing data , or files from the internet , is a method of decreasing download time for large files by getting data from two or more Communication source sources . Overview A program that can handle multi source downloads will connect to one computer and begin downloading the desired file, then find another computer hosting the same file and begin downloading that file as well. The program controls downloads so that each source file provides separate data and the user does not download the same part of the file twice. The program then builds the file on the downloader s computer much faster than it would if it had to wait for the entire file to be downloaded from a single source. This works faster because the rate at which the file servers upload is finite and download rates are generally faster than upload rates. Therefore, downloading from a single server would create a bottleneck if the server s upload rate does not equal your maximum download rate. So distributing the download across multiple servers allows you to utilize all of your download rate potential. Many download manager s use the principles of multi source downloading. Examples of programs that use Multi source downloading ApexDC is an example of a program that uses multi source downloading. The program uses a DC direct connect protocol and downloads a large file by dividing it into smaller parts and downloading the smaller parts from different hosts. http www.apexdc.net External links http patft.uspto.gov netacgi nph Parser?u netahtml srchnum.htm&Sect1 PTO1&Sect2 HITOFF&p 1&r 1&l 50&f G&d PALL&s1 6339785.WKU.&OS PN 6339785&RS PN 6339785 US Patent 6,339,785 Multi server file download Category Internet web stub pt Multi source ... more details

Multi load is a term used to describe multi part games that were developed for 8 bit computer s, such as the ZX Spectrum , Atari 8 bit family Atari and Commodore 64 . Due to the limited memory of these computers, games were initially fairly simple, in order to keep the size of the program code as small as possible, as games would be loaded into memory in their entirety. In time, however, developers began creating games that loaded in only the parts of the game that could be accommodated by the memory constraints typically 48 or 64 kilobytes K of RAM . This multi load approach allowed much larger and complex games to be created, and also allowed games to be created as a series of smaller games such as RoboCop ref cite news url http www.worldofspectrum.org showmag.cgi?mag Crash Issue59 Pages Crash5900022.jpg title RoboCop Review publisher CRASH magazine CRASH date December 1988 ref The user would usually be prompted to stop the Compact Cassette tape when the section had loaded, then prompted to Press play on tape when the next section was required the 8 bit music tribute band , Press Play on Tape use this phrase as their name .
