made up of components such as transistors, diodes, resistors
and capacitors. Integrated circuits are smaller, faster and more
efficient than the individual circuits used in older computers.
Increment: To increase an index variable or counter with a specified
value.
Index: The variable counter within a FOR.. .NEXT loop.
Input: Data fed into the computer to be processed. Input sources
include the keyboard, disk drive, Datassette or modem.

Kilobyte (K): 1,024 bytes. U
Local Network: One of several short-distance data communica-
tions schemes typified by common use of a transmission \ (
medium by many devices and high-data speeds. Also called a
Local Area Network, or LAN.
j j
Loop: A program segment executed repetitively a specified number
of times.
Machine Language: The lowest level language the computer under
stands. The computer converts all high-level languages, such
as BASIC, into machine language before executing any state

puter can execute directly. Also called machine code or object
code.
