Here are the key points about internet protocols: - Protocols are sets of rules that allow devices and programs to communicate with each other over a network or the internet. They define how data should be formatted, transmitted and received between two points. - Some common network/internet protocols include: 1. TCP (Transmission Control Protocol) - Ensures reliable delivery of data packets over IP networks. It establishes a connection between a destination and establishes error checking. 2. IP (Internet Protocol) - Defines how data is packetized and addressed on the internet. It allows devices on a network to communicate with other networks and the internet. 3. UDP (User Datagram Protocol) - A simpler protocol than TCP
