Internet Protocols are a set of rules that govern how data is transmitted over the Internet. They ensure that information sent from one device reaches another correctly and efficiently. The most common protocols include Transmission Control Protocol (TCP) and Internet Protocol (IP), which work together to break data into packets and route them to their destination. These protocols also help devices identify each other on the network using unique addresses, known as IP addresses. This addressing system allows computers, smartphones, and other devices to communicate seamlessly, enabling activities like browsing websites, sending emails, and streaming videos.
