Computer Networking is the practice of connecting computers and computer systems to share resources and exchange information. It involves the design, implementation, and maintenance of a communication infrastructure for data, voice, and video communication.
A computer network can range from a small local area network (LAN) connecting just a few devices to large wide area networks (WAN) connecting many devices across the world. Networking technologies, such as Ethernet, Wi-Fi, and Bluetooth, provide the communication links between devices and enable the exchange of data and information.
Computer networks also enable the sharing of resources, such as printers, storage devices, and internet access. Networking protocols, such as TCP/IP, determine the rules and procedures for communication between devices on a network.
In the modern world, computer networking plays a crucial role in enabling businesses, organizations, and individuals to communicate, collaborate, and access information and resources effectively and efficiently.
