What is the definition of a network?

• A. A group of 2+ computer systems linked together
• B. A single computer
• C. A type of software
• D. A network firewall

Answer: (A)

A network is a group of two or more computer systems linked together so they can communicate and share resources. When multiple devices are connected, they can exchange data, share files and printers, or access the internet through the same connection. A single computer by itself isn’t a network because there’s nothing to connect or share with. Software refers to programs that run on machines, not the connection itself, and a firewall is a security device used to protect a network, not the network definition.
