TCP/IP (Transmission Control Protocol/Internet Protocol) is the foundational suite of protocols that powers the internet and most local networks. TCP ensures reliable communication, while IP handles routing and addressing.
Network topology refers to the arrangement of different elements (links, nodes, devices) in a computer network. It can influence the network’s performance and reliability.
Subnetting divides a network into smaller segments to improve performance and security. Subnets allow for better utilization of IP address space and control over network traffic.
LAN (Local Area Network) connects devices within a small geographical area, such as a home, office, or building. It can be wired (Ethernet) or wireless (Wi-Fi).
