Which option best defines a network in computing?

The best definition of a network in computing is a collection of devices connected to share resources. This definition encompasses the core purpose of networking, which is to facilitate communication and resource sharing among various devices, such as computers, printers, and servers. Networks allow these devices to exchange information, access shared data, and utilize shared services efficiently.

This connectivity can be established using various technologies (like Ethernet, Wi-Fi, etc.) and can take different forms, such as local area networks (LANs), wide area networks (WANs), or the internet, all of which rely on established protocols to ensure proper data exchange and resource sharing. Understanding this fundamental aspect of what constitutes a network helps in grasping larger concepts in IT, including network design, architecture, and management.
