Instruction set
The prime logical and mathematical processes carried out by the microprocessor.
Every high level instruction (including assembler mnemonics) have to be capable
of being distilled down to an instruction that is recognised by the computer's
CPU. A single high level command may invoke a large number of elements from
the CPU's instruction set.
Integer
A whole number with no decimal point.
Integer number
A number with no. fractional part, i.e. a number with no part to the right of the
decimal point - as opposed to a real number which is the integer part plus the
fractional part.
Integrated circuit
A collection of electronic circuit components miniaturised and built onto a single
piece of silicon. (See also Chip)
Intelligent tenninal
A terminal where as well as handling the requirements of the computer's input
and output, local processing power is also available when the terminal is 'offline'.
Interactive
Usually a reference to programs where the hardware computer prompts the user
to provide various types of input - ranging from controlling the spaceship in an
arcade game, to answering questions in educational programs. The action of the
user has an effect in 'real time' on the behaviour of the program.
Interface
The way in and out of a computer, both in electrical and human terms. The 6128
interface is the keyboard (input), and the screen (output) - as well as the facility
for the connection of user peripherals to the various sockets.
