Overview of Different Network Types: LAN, WAN, WLAN, and Peer-to-Peer

This overview presents the fundamental characteristics and types of networks prevalent in our society. We explore Local Area Networks (LAN), which connect devices under the same administrative control mainly within a building, and Wide Area Networks (WAN) that link multiple LANs across different locations. Wireless Local Area Networks (WLAN) provide connectivity for wireless devices via access points, while peer-to-peer networks facilitate a decentralized arrangement among devices without dedicated servers. Understanding these networks is crucial for effective resource management.

  1. By: Kody Shaw Different Network Types

  2. Basic Overview There are many different ways to identify a network in our society. These characteristics are: • What area the network serves • How it stores data • How it manages resources • How it organizes the network • Type of networking devices it uses • Type of media it uses to connect the devices

  3. Local Area Network (LAN) • LAN – group of devices under same administrative control (connected with cables) • In the past, LANs were thought of as a single network in a building • LAN currently includes multiple connected networks that cover several devices, which can be installed throughout many buildings • All networks under a LAN are controlled by one administrator or administrative group • Administrators control security and other control settings for the network

  4. Wide Area Network (WAN) • WAN – A network that connects LANs that are in different physical locations • The Internet is a WAN. It connects several LANs across the world.

  5. Wireless Local Area Network (WLAN) • With a WLAN, wireless devices connect to access points within a specific area • Only the access point is connected to the network host • Connected with copper cabling • WLAN range varies, from 30m to very great distances (short range for indoors, long range for outdoors)

  6. Peer-to-peer • Peer-to-peer has no dedicated servers • Each device has equal rights • Network has no administration • Works best with few computers • Has many disadvantages (No administration, no central security, the more computers results is complex network, might not have central data storage)

  7. Mini Quiz • A _____ is a network that connects LANs that are in different physical locations. • A _____ is a group of devices under the same administrative control (connected with cables). • A _____ network has no dedicated servers. • With a _____, wireless devices connect to access points within a specific area. WAN LAN WLAN Peer-to-peer
