What Is a Computer Cluster?

A computer cluster, referred to as a cluster, is a computer system that uses a set of loosely integrated computer software or hardware to connect and work closely together to complete calculations. In a sense, they can be seen as a computer.

A single computer in a cluster system is often called a node and is usually connected via a local area network, but there are other possible connections.

Clusters are divided into two types: homogeneous and heterogeneous. The differences are:

1. Complete the same job through multiple computers. Achieve higher efficiency.

2. The content and working process of two or more machines are exactly the same. If one crashes, the other can work. ^[2]
