What is parallelism?

In Computer technology, parallelism can be defined as a situation in which the execution of two (2) or more different tasks starts at the same time. Thus, it simply means that the two (2) tasks or threads are executed simultaneously and as such making computation faster.

The types of parallelism.

Generally, there are two (2) main types of parallelism that is used in computer programming and these are:
