Differences Between LAN, WAN, MAN, WLAN & SAN

What is Network?

Network is a group of people or it may be system of interconnected people or entities.

What is Computer Network?

Computer network is a group of computers which are interconnected together to share resources

Basically Computer network is a Digital Communications network through which one can share information, resources, data.

Computer network is a system where the group of computers are interconnected through wires or optical cables or Wi-Fi.

Computer Networks & Differences Between LAN, WAN, MAN, WLAN & SAN Explained on YouTube:

Types of Computer Networks:

Basically computer networks can be classified in to 3 types they are

  • LAN – Local Area Network
  • WAN – Wide Area Network
  • MAN – Metropolitan Area Network

These are the basic variations in the computer networks, again these networks can be classified into

  • WLAN –  Wireless Local Area Network
  • SAN – Storage Area Network or Server Area Network or System Area Network

What is LAN?

The full form of LAN is  Local Area Network

LAN is one type of computer network, that connects the standalone computers through a ethernet cable or through Wireless technology.

LAN covers only a limited area, that may be a room or a flat or a house or a building etc.

At present time, there are two most common technologies to connect the LAN first one via cable i.e. Ethernet and the second one is Wireless technology i.e. Wi-Fi.

What is WAN?

The full form of WAN is Wide Area Network

WAN is the second type of computer network, that connects the computers over a wide area.

WAN extends geographically over a wide area that interconnects multiple Local Area Networks.

WAN is a leased or Private Digital Tele Communications through which one can share a large amount of data or information for example Internet.

What is MAN?

The full form of MAN is Metropolitan Area Network

MAN is the third type of Computer Network, that interconnects the computers over a Metropolitan area.

MAN is one type of Computer Network that can interconnect all the Local Area Networks with in a city or a Metropolitan to make one single WAN.

What is WLAN?

The full form of WLAN is Wireless Local Area Network

WLAN is the wireless LAN that interconnects the group of systems through wireless technology.

WLAN is one type of LAN in which the computers are interconnected through Wi-Fi.

Like LAN, WLAN also covers only a limited area, that may be a room or a flat or a house or a building etc.

What is SAN?

The Full form of SAN is Storage Area Network

SAN is one type of Computer Network, that interconnects the storage devices with servers

SAN enhances the accessibility of the storage devices

SAN is one type of computer network which is dedicated exclusively for storage devices.

The storage devices which are interconnected through SAN they cannot be accessible through other devices which are connected LAN or WAN.

Differences Between LAN, WAN, MAN, WLAN & SAN:

LAN:

  • LAN interconnects the group of computers through a ethernet cable or through Wireless technology.
  • LAN covers only a limited area, that may be a room or a flat or a house or a building etc.
  • In LAN if the group of computers are interconnected through technology i.e. Wi-Fi then it is called WLAN.

WAN:

  • WAN interconnects the group of computers over a wide area.
  • WAN extends geographically over a wide area that can interconnect multiple Local Area Networks.
  • WAN is often a leased or Private Digital Tele Communications through which one can share a large amount of data or information for example Internet.

MAN:

  • MAN interconnects the computers over a Metropolitan area.
  • MAN is one type of Computer Network that can interconnect all the Local Area Networks with in a city or a Metropolitan to make one single WAN.

WLAN:

  • WLAN is the wireless LAN that interconnects the group of systems through wireless technology.
  • WLAN interconnects the group of computers through Wi-Fi.
  • WLAN covers only a limited area, that may be a room or a flat or a house or a building etc.

SAN:

  • SAN interconnects the storage devices with servers.
  • SAN enhances the accessibility of the storage devices.
  • SAN is dedicated exclusively for storage devices.
