Comparison Between LAN and WAN

FeatureLAN (Local Area Network)WAN (Wide Area Network)
Full FormLocal Area NetworkWide Area Network
Geographical CoverageCovers a small area such as a room, office, building, or campusCovers a large area such as a city, country, or the world
OwnershipUsually privately owned by an individual or organizationUsually owned and managed by communication companies or service providers
PurposeConnects devices within a limited areaConnects multiple LANs and networks over long distances
Devices ConnectedMainly connects hosts such as computers, printers, and serversMainly connects networking devices such as routers, switches, and modems
Communication SpeedGenerally high speedUsually slower compared to LAN
Transmission MediaEthernet cables, Wi-FiFiber optics, leased lines, satellite links, telephone lines
CostLower installation and maintenance costHigher installation and maintenance cost
Data Transfer DelayVery low delayHigher delay due to long-distance communication
SecurityMore secure because it is privateLess secure compared to LAN because communication occurs over public or leased networks
ExamplesHome network, school lab, office networkBanking network, airline reservation system

  Introduction to Local Area Network (LAN) What is a LAN? A Local Area Network (LAN) is a network that connects devices within a limited geographical area such as: A home An office A building A school campus A LAN is usually privately owned and managed by an individual or organization. Definition A LAN is a network that interconnects hosts in a single office, building, or campus to enable communication and resource sharing. Characteristics of a LAN 1. Limited Geographical Area A LAN covers a small area compared to larger networks like WANs. Examples: Computer lab in a college Office network in a company Home Wi-Fi network 2. High-Speed Communication Since devices are located close to each other, LANs provide: Faster data transfer Lower delay Efficient communication 3. Private Ownership LANs are generally owned and maintained by: Schools Companies Universities Home users 4. Resource Sharing LANs allow multiple users to shar...
