What is a group of Computers called?

A group of computers is commonly called a Cluster. Other collective nouns you may see include Caste and Network.

Collective nouns for computers refer to groups or collections of computers that work together towards a common goal or function. These groups are designed to increase efficiency, improve performance, and complete complex tasks that may be challenging or even impossible for a single computer acting independently. Just as human societies have collective nouns, such as a group of people being referred to as a "team" or "crowd," computer systems have various collective nouns to denote their joint functioning. One commonly known collective noun for computers is a "cluster." A computer cluster is a group of connected computers that collaborate as a single entity to perform computationally extensive tasks. Clusters are commonly found in computational research, scientific applications, or data processing tasks where each computer handles a portion of the workload, leading to faster and more reliable outcomes. Another term used to describe a collective noun for computers is "grid." In a grid computing system, a group of computers from different locations are combined to form a distributed network. Grid computing allows sharing of computational resources, data storage, and processing power between multiple computers for parallel processing or to solve complex problems collectively. Grids are employed in various fields such as astronomy, weather forecasting, or pharmaceutical research. Additionally, "botnet" is another collective noun used in relation to computers. While botnets often carry negative connotations, they illustrate a grouping of compromised computers controlled by a central entity called a command and control server. These computers, known as bots, are often manipulated by malicious actors to carry out nefarious activities like launching coordinated cyber-attacks, spamming, or unauthorized data acquisition. In summary, collective nouns for computers describe groups of computers working as cohesive units, such as clusters, grids, or botnets. These collective structures optimize computer resources, enhance computational capabilities, and provide solutions to complex problems by leveraging the combined strength and collaboration of multiple computers.
