Accelerometer: The device inside Iphones and android based phones that uses a three way axis to tell if the phone is tilted in one direction or the other. It is used by applications so it can change the angle of the screen or in other applications like games to help you play them.
Access Time: The ammount of time something takes to find a piece of information and allow it to be used by other devices.
ACR: Audio Communications Riser - a slot that is only used by large OEMs to add cheap devices to their computers. Since ACR devices are software based, they often times sap a lot of CPU resources.
ActiveX: ActiveX is a loosely defined set of technologies developed by Microsoft in 1996 for sharing information among different applications.
ActiveX Controls: ActiveX controls, mini program building blocks, can serve to create distributed applications working over the Internet through web browsers. Examples include customized applications for gathering data, viewing certain kinds of files, and displaying animation.
ADSL: Asymmetric Digital Subscriber Line - Like ISDN, ADSL uses standard phone lines to deliver high-speed data communications. But while ISDN's transmission speed is limited to 64 kbps, ADSL technology can deliver upstream (from the user) speeds of 640 kbps and downstream (to the user) speeds of more than 6 mbps. Even better, ADSL uses the portion of a phone line's bandwidth not utilized by voice, allowing for simultaneous voice and data transmission.
AFTP: (Anonymous File Transfer Protocol) A host that provides an FTP service may additionally provide anonymous FTP access. Users typically log into the service with an 'anonymous' account when prompted for user name. Although users are commonly asked to send their email address in lieu of a password, no verification is actually performed on the supplied data. Many FTP hosts whose purpose is to provide software updates will provide anonymous logins.
AGP: Accelerated Graphics Port - Brown slot located nearest to the processor on most motherboards. AGP ports are used exclusivly for graphics cards and are set back and keyed differently so that other expansion cards will not fit in them.
AMD: Advanced micro devices is an acronym developed by Intel for a set of there processors.
AMR: Audio Modem Riser - like the ACR, AMR's are extremely low cost software devices that can do a host of functions. Since they are software based, they use quite a bit of CPU resources.
Anti Alaising: The method in which jagged lines in 3d enviroments (easily seen in the horizon of games) are removed and smoothed out for a picture that is easier on the eyes.
Apache Server: "Web Server" software used by internet providers as "server" / "services".
API: Application Program Interface - The API is a set of functions that programmers use to develop software for specific purposes or to interface with other software. For example, the windows api allows programmers to develop software for windows. The api for a graphics suite would allow programmers to develop software for that graphics suite.
Apps: Applications or programs that run on your computer, tablet, and/or smart phone.
ASCII: American Standard Code for Information Interchange - The ASCII set of 128 characters includes letters, numbers, punctuation, and control codes (such as a character that marks the end of a line). Each letter or other character is represented by a number: an uppercase A, for example, is the number 65, and a lowercase z is the number 122. Most operating systems use the ASCII standard, except for Windows NT, which uses the suitably larger and newer Unicode standard.
Asic: Application Specific Integrated Circuit - ASIC is a custom microchip designed for a specific application.
AT Power connector: Mother Board Connects for an AT power supply.
ATX Power Connector: ATX - AT Extended form factor. Referrs to a standard for motherboard configuration and layout called the ATX Motherboard Specification. The AtX power connector replaced the older standard and allows the power supply to be turned on or off by the computer itself, rather than just by a physical switch.
