What is the definition of a computer network?

The definition of a computer network is best captured by the concept of two or more computers connected for sharing resources. This definition highlights the fundamental purpose of computer networks, which facilitates communication and resource sharing between multiple devices.

In a computer network, computers can connect and interact with one another through various means, such as wired or wireless connections. This connectivity allows for the sharing of data, files, and other resources like printers and internet access. In practical terms, computer networks can range from small local area networks (LANs) within a home or office to extensive wide area networks (WANs) that span large geographic areas.

The other options do not accurately represent what constitutes a computer network. For instance, a single computer used for processing refers more to an isolated system and does not involve any connection with other devices. A collection of software applications does not embody the concept of interconnectivity between computers, and a type of internet connection describes a method of access rather than the network itself. Therefore, the correct choice emphasizes the essential characteristic of networking: the interconnection between multiple computing devices for the purpose of collaboration and resource sharing.
