Again, as we have
learned, the only thing a microprocessor does is to mimic binary arithmetic.
Accordingly, in the most fundamental terms, output is
simply the task of receiving back from the processor the results
of binary arithmetic tasks the microprocessor has performed.
user only sees the results that have been decoded by
various output devices:
Monitor - The computer graphics adapter translates 0s and 1s into
video signals for the computer monitor.
- Printers -
0s and 1s can also be translated into instructions that can be acted
upon by various printer technologies:
- laser printers
- ink-jet printers
Both input and output devices attach to the computer's internal communication
"highways" (called "buses") through
a variety of ports on the computer's surface, including:
