Types of computer networking

types of networking

There are several different types of computer networks. Computer networks can be characterized by their size as well as their purpose.

The size of a network can be expressed by the geographic area they occupy and the number of computers that are part of the network. Networks can cover anything from a handful of devices within a single room to millions of devices spread across the entire globe.

Some of the different networks based on size are:

  • Personal area network, or PAN
  • Local area network, or LAN
  • Metropolitan area network, or MAN
  • Wide area network, or WAN

    Personal Area Network

    A personal area network, or PAN, is a computer network organized around an individual person within a single building. This could be inside a small office or residence.ผลการค้นหารูปภาพสำหรับ personal area network

    Local Area Network

    A local area network, or LAN, consists of a computer network at a single site, typically an individual office building. A LAN is very useful for sharing resources, such as data storage and printers.ผลการค้นหารูปภาพสำหรับ local area network diagram

    Metropolitan Area Network

    A metropolitan area network, or MAN, consists of a computer network across an entire city, college campus or small region. A MAN is larger than a LAN, which is typically limited to a single building or site.ผลการค้นหารูปภาพสำหรับ metropolitan area network

    Wide Area Network

    A wide area network, or WAN, occupies a very large area, such as an entire country or the entire world. A WAN can contain multiple smaller networks, such as LANs or MANs. The Internet is the best-known example of a public WAN.  ผลการค้นหารูปภาพสำหรับ wide area network diagram
