complex, and as systems are updated, the programs

must be revised to meet the new demands of the fleet.
Operational programs for mainframe computers are
supported by technical teams external to the command.
Two examples of mainframes are the AN/UYK-7(V)
and the AN/UYK-43(V) computers. They are
general-purpose, militarized, digital data computers
with large-scale memories, I/O capabilities, and
multiprocessing capabilities that allow a number of
CPUs to operate simultaneously in the same system.
They interface with other mainframes and peripherals
in the data processing subsystem, the display
subsystem, and the communication subsystem.
Training is obtained through formal C schools and is
NEC producing. Figure 1-3 is an example of one of the
Navy’s mainframe computers.
Some physical features of mainframe computers
are highlighted as follows:
l Large rugged frame or cabinet —Contains
individual modules or units; central processor unit
(CPU), memory modules, input/output controller
exchangers for each module or unit, power supply
unit(s), and blower motors for cooling.
