In parallel systems, large jobs are divided into smaller ones which are then processed simultaneously(hence, the name parallel). Since, the task is broken down, the efficiency largely increases.

Parallel computing has a number of advantages over other paradigms:

-It leads to a large increase in efficiency.

-It helps in power consumption.

It is the hence, the most dominant paradigm in computer architecture.

The disadvantages regarding parallel computing are:

-The processes difficult to write.

-Gives more scope for bugs to crawl in.
