is short for Input/Output
. This is what enters your machine, pending processing -- and what exits your machine, processed. If you are programming, and you instuct the machine to echo
something you are generating OUTPUT
. The stuff you are instructing the machine to say is considered INPUT
(cpu sez: I wanna make this 4, yes.)
input (2 x 2)--->--->--->|CPU| |VID|--->MONITOR: 4
This example: you send 2*2 (input) to the CPU, beg and plea for it to calculate, it calculates, and goes through neseccary stuff, and the stuff you get (2*2=4) on the monitor
is your output.
