Which term refers to an individual computer or device connected to a network?

The term that refers to an individual computer or device connected to a network is "node." In networking terminology, a node is any active electronic device that communicates over a network. This includes computers, printers, and any other devices that can send, receive, or forward data.

While "host" can also refer to devices on a network, it specifically denotes any computer or device that is assigned an IP address and can be reached over the network. Thus, although it can be synonymous with a node in some contexts, the term "node" is broader and encompasses all connected devices.

A "server" is a specific type of host that provides services or resources to other computers on the network, such as data storage or application hosting. "Client" refers to a device or software that accesses services provided by a server but does not perform server functions itself. These terms describe specific roles within a network and highlight the diverse functions that nodes can perform.
