What is grid computing? It is distributed computing where autonomous computers perform independent tasks. It is interconnected computing where a computing platform is delivered to consumers. It is parallel and distributed computing where computer infrastructure is offered as a service. It is parallel computing where autonomous computers act together to perform very large tasks.

It is parallel computing where autonomous computers act together to perform very large tasks.

Explanation:

Grid computing can be defined as a parallel computing where autonomous computers act together to perform very large tasks.

This entails that its a computing process whereby several computers work together side by side in other to solve a large chunk of problem.

This process always ensures efficiency and effectiveness.
