I/O SERIAL DATA OPERATIONS Serial data
operations exchange information via a single path, line,
or wire. The channel/port itself is made up of several
wires, but only one is used to transfer the binary data.
INTERCOMPUTER I/O OPERATIONS
Parallel channels are often used to communicate
between two stand-alone computers. In this mode, the
computers will appear as external devices to each other.
One computer will be designated the transmitting
(outputting) computer; the other computer will be
designated the receiving (input) computer.
Learn all you can about how input/output
operations enable the computer to communicate with
and control the variety of equipments used in todays
computer systems. Learn about the internal I/O process
and the interfacing process. This will help you to
troubleshoot and diagnose input/output problems and
to repair and/or replace I/O parts.
