Series 260: Microprocessors
Course 262: Input/Output Devices I-User Level
Covers many of the input/output devices that make up a typical computer system. Explores communication-the successful transmission of information between computers-at length. Discusses both the user/machine interface and the machine/machine interface, as well as the various network configurations. Concludes with two "real-world" examples of how microprocessors are connected to I/O devices.
TPC Training Systems is authorized by IACET to offer 0.5 CEUs for this program.
