Computer networking is the system that connects computers and devices so they can communicate and share data across local and global networks using protocols, hardware, and addressing systems.
Network protocols are standardized rules that define how devices communicate and exchange data across a network. Examples include TCP/IP, HTTP, DNS, and DHCP, which govern different aspects of data transmission.
Common networking devices include routers (directing traffic between networks), switches (connecting devices within a network), modems, wireless access points, and network cables for physical connections.
IP addressing is the system that assigns unique identifiers to devices on a network, allowing data to be routed to the correct destination. IPv4 and IPv6 are the two current addressing standards.
Advanced networking knowledge helps IT professionals configure infrastructure, manage traffic, troubleshoot connectivity issues, maintain secure communication, and support enterprise systems that depend on reliable networks.
