Which term describes a group of 2 or more computers linked together?

The term that describes a group of two or more computers linked together is "network." A network allows multiple computers to communicate with each other, share resources such as files and printers, and access the internet or other networks. This connectivity can happen through wired connections, such as Ethernet cables, or wireless connections, such as Wi-Fi.

A "system," while it can refer to a collection of components working together, usually pertains more to the functioning of a single computer or organizational structure rather than the interconnection of multiple computers.

A "server" refers to a computer or system that provides data, resources, or services to other computers, known as clients, within a network. While it plays a vital role in networking, it does not encompass the entire concept of linked computers.

The term "web" typically refers to the World Wide Web, which is a system of interlinked hypertext documents accessed via the internet, and is not specifically about computers linked together in a direct network sense.

Therefore, the correct term for a group of two or more computers linked together is "network."
