WAN ,LAN TOPOLOGIES AND DATA LINK FRAME | Installing and Configuring Network | SNS INSTITUTIONS

Описание: LAN (Local Area Network) and WAN (Wide Area Network) are computer networks that differ in their geographical coverage, with LANs spanning small areas like homes or offices and WANs covering larger areas like cities or countries. The data link layer (Layer 2 of the OSI model) transmits data in frames, which include a header with source and destination MAC addresses, a payload with the actual data, and a trailer with error-checking data.
