What is a series of connected computers within a confined space called?

A series of connected computers within a confined space is referred to as a Local Area Network (LAN). A LAN typically covers a small geographic area, like a single building or a campus, allowing multiple devices—such as computers, printers, and servers—to communicate and share resources efficiently.

This type of network is characterized by its high data transfer rates, relatively low latency, and the ability to facilitate direct communication among connected devices. LANs are common in environments like homes, schools, and small to medium-sized businesses, where they support system productivity and resource sharing.

In contrast, a Wide Area Network (WAN) covers a much larger area, potentially spanning cities, countries, or even continents, and is utilized for connecting multiple LANs. A backbone refers to a primary data route between multiple networks, often high-capacity, while the Internet is a vast network of networks that connects millions of devices globally, facilitating broader communication but not confined to a single localized space like a LAN.
