  •  A<br /> <br /> AGP: Accelerated Graphics Port, a new connecting slot for graphics cards that exist in the motherboard Pentium II computers.  needles (printer " needles" ): see matrix. <br /> AMD processors known manufacturer, compatible with the Intel x86 series (Advanced Micro Devices). <br />AmiPro: Word Processor by Lotus, now improved and called WordPro.<br />  Antivirus: Computer application designed to detect and remove viruses. <br /> API: Application Programming Interface (Applications Programming Interface): a series of functions that are available for programs for a certain environment <br />Apple: Home computer maker, maker of computers like the Apple II, Lisa, Macintosh and iMac. <br />Archive: It is often used as synonymous with file. In the world of compressors, often make a distinction, saying that several original files are compressed and packed into an archive. <br />Autodesk: House software developer, author of applications such as AutoCad, 3D Studio, Animator, AutoSketch, etc. <br />B<br />BAT: Extension of a file consists of a lot (batch) Two orders. <br />BCD: Binary Coded Decimal (Binary Coded Decimal). Acronym used to refer to a special form of binary coded decimal numbers, using 4 bits for each decimal digit, so a byte can store two decimal numbers. BIOS: System Basic Input / Output (Basic Input Output System). Typically involve one or more ROM chips (usually EPROMs) containing the basic routines and out, the first steps you should take a computer to fire, the basic system configuration, etc.. <br />Bit: The smallest unit of information that can store and manage a computer equivalent to a 0 or 1. <br />bitmap (or bitmap). One type of images to your computer, which stores information about the points that make and color of each point (as opposed to vector images).This means that the larger picture is lost definition, are " fat points."  <br />Borland: Known software maker, author of languages such as Turbo Pascal, Turbo C, Delphi, C Builder, JBuilder, etc., and applications such as Paradox, Quattro Pro, etc. It has now been renamed and is called Inprise. <br />Bps: Bits per second: the unit used to measure the actual transfer speed of a modem or a serial connection. <br />Buffer: buffer for temporary data storage in communication between a computer and an external device (eg a printer). When is a computer program that makes the task of intermediate storage for data that are sent to the printer, the program is often called Spooler. <br />Bug: error in a program, which means that in certain circumstances may not behave correctly. <br />Byte: A basic unit of information. In practice, one can consider that a byte is the amount of space required to store a letter. Have multiples as the Kilobyte, Megabyte, Gigabyte and Terabyte. Internally, it corresponds to 8 bits. <br />C<br />Cache: A special type of memory, faster than normal RAM (and more expensive), which gets in the way of data ranging from the processor to the RAM. Thus, all information that goes to the processor RAM is left temporarily stored in the cache.When re-read information, it first checks if it is in the cache, if there is no need to go to RAM searching. In practice, very often repetitive operations or work with repetitive data, which makes owning cache to help speed up your computer to normal operation. Today it is often also distinguish cache " first level" and " second level" . The first level is within the processor itself. The second level is on the motherboard, is larger and somewhat slower. <br />CAM: Computer-aided manufacturing (Computer Aided Manufacturing). or Country: In the world of databases, each of the data that make up a record (or tab).For example, in the file for each
