Various Types of Network

Introduction

Two electronic devices are said to be in a network when a process in one is capable of exchanging data with that of another (gadget). Networks, therefore, serve as a medium of exchange between nodes of computers or sets of devices. It typically consists of serves, networking devices and computer systems linked together so as to share resources like printer and file server.

Various types of network

  1. Personal Area Network (PAN)

PAN refers to a computer network formed around one person in a single building. The network can be inside a home or a small office. In its typical form, PAN includes one or several computers, video consoles peripherals, and telephones among other personal entertainment gadgets. If several people use the network within a home setting, the network often termed HAN (Home Area Network). PAN provides impressive flexibility.

  1. Local Area Network (LAN)

LANs connect low voltage devices and groups of computers across short distances like within buildings or between two or three structures in close nearness to each other. The networks enable the devices to share resources and information efficiently. LANs can be set up with relatively less costly hardware like hubs, Ethernet cables, and adapters. While the smallest LANs consist of two computers, larger ones accommodate up to thousands of devices.

  1. Wide Area Network (WAN)

WAN, as its name suggest, spans expansive physical distance. The internet is, therefore, the largest of this type of network since it extends the entire planet. WAN basically refers to a geographically-dispersed assortment of LANs. Network devices called routers to connect LANs to a wide area network. In IP networking a router is charged with the responsibility to maintain the address of both a LAN and a WAN. This type of network utilizes technologies like Frame Relay, ATM and X.25 to connect devices over expansive distances.

  1. Storage-Area Network (SAN)

SAN is a dedicated, high-speed type of network whose role is to connect shared storage devices to a number of servers. Unlike LAN and WAN, this network does not rely on either LAN or WAN to move storage resources. Instead, it transfers the resources from the existing networks and put them in high-performance networks. SANs are accessible in the same way as a drive connected to a server. They are further classified into virtual, converged an unified SANs.

  1. Wireless LANs WLANs

provide a wireless connection over short distances. They utilize infrared or radio

signals as opposed to conventional network cabling. Wireless Local Area Networks entail a mobile user connecting to a local area network via a wireless connection. The networks typically outspread to an existing wired network. They are formed by linking a network device (called Access Point) to a wired network.

Conclusion

While there are several types of networks in existence, the above and LAN and WAN, in particular, are popular and hence the most prevalent. Other types that are less common include Campus Area Network, one that spans several LANs but still too small to be considered MAN and System Area Network, which links high-performance devices to top-speed connections using cluster arrangements.
