A computer network is a group of computers connected together to communicate and share resources, such as internet connections, printers, or files.
Why Do We Need Networks?
Without networks, transferring files would require physical media like USB drives. Networks enable instant communication, centralized data management, and the modern internet.
Practical Example
Your home Wi-Fi is a network. It connects your phone, laptop, and smart TV to a central router, which then connects to the global internet.
