Glossary input: The data or instructions you provide to a computer, communication device or other peripheral device from the keyboard or external or internal storage devices. The data sent (or output) by the sending computer is input for the receiving computer. instruction: Statements or commands that specify how to perform a particular task. interface: 1) Hardware and/or software components of a system used specifically to connect one system or device to another. 2) To physically connect one system or device to another to exchange information. 3) The point of contact between user, the computer, and the program, for example, the keyboard or a menu. interrupt request: A signal that gives a component access to the processor. I/O: Input/output. Refers to acceptance and transfer of data to and from a computer. I/O devices: Equipment used to communicate with the computer and transfer data to and from it. IrDA 1.1: An industry standard that enables cableless infrared serial data transfer at speeds of up to 4 Mbps. J jumper: A small clip or wire that allows you to change the hardware characteristics by electrically connecting two points of a circuit. K K: Taken from the Greek word kilo, meaning 1000; often used as equivalent to 1024, or 2 raised to the 10th power. See also byte and kilobyte. KB: See kilobyte. keyboard: An input device containing switches that are activated by manually pressing marked keys. Each keystroke activates a switch that transmits a specific code to the computer. For each key, the transmitted code is, in turn, representative of the (ASCII) character marked on the key. kilobyte (KB): A unit of data storage equal to 1024 bytes. See also byte and megabyte. L level 2 cache: See cache. Light Emitting Diode (LED): A semiconductor device that emits light when a current is applied. User's Manual Glossary-9
