A Wide Area Network (WAN) is a network that spans a large geographic area, often using leased telecommunication lines to connect multiple LANs or MANs. Elaboration: Unlike LANs, which are limited to small areas, WANs connect cities, countries, or even continents. They rely on: Example: WANs often face issues like latency, security risks, and high…

A Local Area Network (LAN) is a network that connects computers and devices within a limited geographical area, such as a home, office, or campus, using wired (Ethernet) or wireless (Wi-Fi) communication. Elaboration: LANs allow fast communication and resource sharing (files, printers, internet access) among connected devices. They have: Example: A school’s computer lab, where…

Network topology refers to the physical or logical arrangement of devices (nodes) and connections (links) in a network. Elaboration: Topology determines how data flows between devices, affects performance, fault tolerance, and scalability, and influences network cost and maintenance. Types of Network Topologies: Different topologies are chosen based on factors like cost, data traffic, redundancy, and…

A network is a system of interconnected devices (computers, servers, routers, etc.) that communicate and share resources through wired or wireless connections using standardized communication protocols. Elaboration: A network allows devices to exchange data, share files, printers, and resources, and connect to the internet. Networking enables communication between computers, mobile phones, IoT devices, and servers…
