What is the term for a group of computers and devices connected in a network?

The term for a group of computers and devices connected in a network is "Network." A network allows these computers and devices to communicate with each other, share resources such as files and printers, and access the internet. Networks can vary in size and complexity, ranging from small local area networks (LANs) within a home or office to large wide area networks (WANs) that span vast geographical areas.

The other options refer to different concepts: "System Architecture" typically denotes the structural design of systems, including hardware and software components, rather than the interconnection of devices. "Web Structure" is not a standard term in networking; it might refer to the arrangement of content on the internet but is not relevant to describing connected devices. "Cloud System" generally refers to services and resources provided over the internet, often involving storage and applications, but does not specifically denote a group of connected devices in the way that "network" does.
