The word protocol is derived from the Greek word “ protocollon ” which means a leaf of paper glued to manuscript volume. In computer protocols means a set of rules, a communication language or set of standards between two or more computing devices . Protocols exist at the several levels of the OSI (open system interconnectivity) layers model. In the telecommunication system, there are one more protocols at each layer of the telephone exchange. On the internet, there is a suite of the protocols known as TCP/IP protocols that are consisting of transmission control protocol, internet protocol, file transfer protocol, dynamic host configuration protocol, Border gateway protocol and a number of other protocols. In the telecommunication, a protocol is set of rules for data representation, authentication, and error detection . The communication protocols in the computer networking are intended for the secure, fast and error free data delivery between two communication devices. Communication ...

A ACPI (Advanced Configuration and Power Interface) - Specification developed by Intel, Compaq, Phoenix, Microsoft and Toshiba to control power on notebooks and other devices. Windows 98 and Windows 2000/XP support ACPI. ATC (Advanced Transfer Cache) - A type of L2 cache contained within the Pentium processor housing that is embedded on the same core processor die as the CPU itself. ANSI (American National Standards Institute) - A non-profit organization dedicated to creating trade and communications standards. ASCII (American Standard Code for Information Interchange) - A popular standard for writing letters and other characters in binary code. Originally, ASCII characters were seven bits, so there were 127 possible values. ASCII has been expanded to an 8-bit version, allowing 128 additional values. asynchronous SRAM - Static RAM that does not work in step with the CPU clock and is, therefore, slower than synchronous SRAM. AT - A form factor no longer produced, in which the mother...
