A **network protocol** is a set of rules and conventions that govern the communication between devices on a computer network. It ensures data is transmitted accurately and efficiently, enabling different systems to understand and respond to each other. Common examples of network protocols include HTTP, FTP, TCP/IP, and UDP, each serving specific functions in facilitating network connectivity and data exchange. Understanding network protocols is essential for troubleshooting, optimizing performance, and securing communication within digital networks.
