Parallel systems
Most computers having only one CPU. However , there is atrend towards multiprocessor systems, Such systems have
more than one processor in close communication, sharing the
computer bus, the clock, and some times memory and
peripheral devices. These systems are referred as “Tightly
coupled” systems. A system consisting of more than one
processor and it is a tightly coupled, then the system is Parallel
system. In parallel systems number of processors executing
their jobs parallel. There are several reasons for buildings
such systems.

Parallel systems
• One advantage is increased “throughput” . The performance
of the CPU is measured in terms of quantity called said to be
“throughput” By increasing the number of processors
(CPU’s), to get more work done in a shorter period of time.
• Multiprocessor can also save money compared to multiple
single systems because the processor can share peripherals,
Cabinets, and power supplies. Another advantage for multi
processor systems is that they increase reliability.
