Computer networks are categorised based on their coverage area into\u00a0Local Area Networks (LANs), Metropolitan Area Networks (MANs)<\/strong>\u00a0and\u00a0Wide Area Networks (WANs).<\/strong>\u00a0A\u00a0computer network<\/strong>\u00a0can be defined as an interconnected system of computers and devices that facilitates digital communication using a set of common protocols. While LANs leverage\u00a0Ethernet standards<\/strong>\u00a0over cables and WiFi, WANs employ telecom infrastructure like\u00a0fibre, cellular,\u00a0<\/strong>and\u00a0satellites.<\/strong>\u00a0By using fibre rings and wireless systems, MANs fill the gap between LANs and WANs. This hierarchy delivers connectivity from personal through global scales, forming the backbone of digital communication.<\/p>\r\n

Types of Network - LAN, WAN, MAN, PAN<\/h2>\r\n

Computer networks can be classified into the following main categories based on their scale and purpose:<\/p>\r\n
