Computer networking refers to the practice of connecting multiple computers and devices to enable communication, resource sharing, and data transfer. It involves the use of hardware, software, and protocols to establish and maintain a network infrastructure. Networks can be local (LAN) or wide area (WAN), and can be wired or wireless. Computer networking allows for the sharing of files and resources, access to the internet, collaboration, and efficient data transmission. It encompasses various technologies such as routers, switches, protocols like TCP/IP, and network security measures to ensure reliable and secure communication between connected devices.
