What is the definition of a network?

• A. A network is a group of computers and other devices (such as printers) that are connected by some type of transmission media.
• B. A network is a single computer with a printer.
• C. A network is a set of software programs.
• D. A network is only wireless devices.

Answer: (A)

A network is a group of devices such as computers and printers that are connected by some type of transmission medium so they can communicate and share resources. This definition emphasizes both the interconnection of multiple devices and the ability to exchange data or share things like files, printers, or internet access, whether the links are wired (like Ethernet cables) or wireless (like Wi‑Fi).

That’s why the best choice fits: it describes multiple devices connected by a transmission medium for communication and sharing. A single computer with a printer isn’t a network because there aren’t multiple devices to communicate and share resources. A set of software programs isn’t a network on its own, since software runs on devices rather than connecting them. And saying a network is only wireless excludes wired networks, which are also common.
