Network Types

• LAN - Local Area Network
• WLAN - Wireless Local Area Network
• WAN - Wide Area Network
• MAN - Metropolitan Area Network
• SAN - Storage Area Network, It can also refer with names like System Area Network, Server Area Network, or sometimes Small Area Network
• CAN - Campus Area Network, Controller Area Network, and often Cluster Area Network
• DAN - Desk Area Network

LAN - Local Area Network

LAN connects networking devices with in short spam of area, i.e. small offices, home, internet cafes etc. LAN uses TCP/IP network protocol for communication between computers. It is often but not always implemented as a single IP subnet. Since LAN is operated in short area so It can be control and administrate by single person or organization.

WAN - Wide Area Network

As “word” Wide implies, WAN, wide area network cover large distance for communication between computers. The Internet it self is the biggest example of Wide area network, WAN, which is covering the entire earth. WAN is distributed collection of geographically LANs. A network connecting device router connects LANs to WANs. WAN used network protocols like ATM, X.25, and Frame Relay for long distance connectivity.

Wireless - Local Area Network

A LAN, local area network based on wireless network technology mostly referred as Wi-Fi. Unlike LAN, in WLAN no wires are used, but radio signals are the medium for communication. Wireless network cards are required to be installed in the systems for accessing any wireless network around. Mostly wireless cards connect to wireless routers for communication among computers or accessing WAN, internet.

MAN - Metropolitan Area Network

This kind of network is not mostly used but it has its own importance for some government bodies and organizations on larger scale. MAN, metropolitan area network falls in middle of LAN and WAN, It covers large span of physical area than LAN but smaller than WAN, such as a city.

CAN - Campus Area Network

Networking spanning with multiple LANs but smaller than a Metropolitan area network, MAN. This kind of network mostly used in relatively large universities or local business offices and buildings.

SAN - Storage Area Network

SAM technology is used for data storage and it has no use for most of the organization but data oriented organizations. Storage area network connects servers to data storage devices by using Fiber channel technology.

SAN - System Area Network

SAN, system area networks are also known as cluster area network and it connects high performance computers with high speed connections in cluster configuration.

Local area Networking

• Networking deals with interconnected groups of machines talking with each other. Is a very different field than operating systems. Have a lot of standards stuff because everyone must agree on what to do when connect machines together.
• What is a network? A collection of machines, links and switches set up so that machines can communicate with each other. Some examples:
  • Telephone system. Machines are telephones, links are the telephone lines and switches are the phone switches.
  • Ethernet. Machines are computers, there is one link (the ethernet) and no switches.
  • Internet. Machines are computers, there are multiple links, both long-haul and local-area links. The switches are gateways.

Computer Networking Information

Computer Networking is a focus within engineering that deals with communication between computer systems or devices. Computer networking is often considered a sub-discipline of a few areas: telecommunications, computer science, information technology and/or computer engineering. Computer networks rely heavily on the theoretical and practical application of each of these engineering disciplines.
