Computer Networking Protocols

Computer networking protocols are sets of rules that govern data communication between devices on a network. They ensure reliable, efficient, and secure data exchange across various networks . Protocols like TCP/IP, HTTP, and FTP facilitate communication between devices using standardized formats and procedures . Each protocol has its own set of rules for addressing, routing, and error-checking . For instance, TCP ensures error-free transmission by checking packets for errors and retransmitting them if necessary . Protocols like DNS and DHCP manage network resources, such as IP addresses and hostnames, to facilitate device identification and connection establishment .
