What is the term for the connection of two or more computers to share data and hardware?

The term for the connection of two or more computers to share data and hardware is "network." A network allows individual computers to communicate with each other, share resources such as printers and storage devices, and transfer information efficiently. This concept is fundamental to modern computing because it enables collaboration and resource optimization among users.

In the context of computing, a network can take various forms, such as local area networks (LANs) for small, localized setups or wide area networks (WANs) that connect distant locations. The ability to connect multiple computers effectively is the backbone of information exchange in both personal and professional environments.

The other options represent different aspects of computer systems: a system refers to a set of connected components that work together, a server is a computer designed to provide data or services to other computers in a network, and a database is an organized collection of data that can be accessed and managed. None of these terms specifically captures the idea of interconnected computers for the purpose of sharing resources and information like "network" does.
