A computer network allows computers to communicate and share data and information. It connects two or more computers together, allowing them to share resources like printers and scanners, exchange data, and communicate with one another either via wires or wireless signals. While computer networks provide benefits like increased speed, reduced costs, and centralized management, they also have drawbacks such as high installation costs and potential server or cable failures.
