Networking Fundamentals refers to the basic concepts and principles that govern how computers and devices communicate with each other. This includes understanding different types of networks, such as LAN (Local Area Network) and WAN (Wide Area Network), as well as the hardware involved, like routers and switches. Additionally, networking fundamentals cover protocols, which are sets of rules that dictate how data is transmitted over a network. Common protocols include TCP/IP (Transmission Control Protocol/Internet Protocol) and HTTP (Hypertext Transfer Protocol). Mastering these basics is essential for anyone looking to work in IT (Information Technology) or related fields.
