What is the LAN Full Form in Computer?

In computer networking, LANs are used to connect and communicate information among various devices like mobiles, computers, tablets, printers, etc. The range of a LAN network can be a floor of the office, a room, an organization having one or two buildings on the same premises, a laboratory, a school, and a college. The connectivity of these devices is done by means of wires, ethernet cables, fibre optics, or Wi-Fi.

LANs are a secured network for users as only the authentic users in the network can access other nodes or shared resources. LAN (LAN Full Form: Local Area Network) can be extended up to 1 km. The data transmission in LAN is at high speed of 10Mbps(Megabits per second) to 1000 Mbps.

Characteristics of LAN 

Among the other types of networks, LAN (LAN Full Form: Local Area Network) is the choice of the majority of users because of the following characteristics it holds:

  • It transmits data at a very high rate which increases the efficiency of the overall transmission.
  • It supports transmission mechanisms like optic fibre, ethernet cable, WI-FI, etc.
  • It is not costly as compared to other types of networks.
  • It provides privacy, so no outside network or organization can temper data.

Advantages of LAN

With the invention of LANs (LAN Full Form: Local Area Network) in 1970, the networking world witnessed a revolution in data transmission. The following advantages were the reason for this revolutionary invention:

  • Data security is ensured as data is collected on the server computer only.
  • Hardware cost is reduced by the introduction of LANs.
  • A single point of the internet can be used by various devices connected through LAN (LAN Full Form: Local Area Network).
  • Enhances the communication between the devices linked through LAN networks.

Disadvantages of LAN 

Just like a coin has two sides, a head and a tail, in a similar manner, everything comes with its pros and cons attached with it. Having discussed the advantages of LAN Full Form: Local Area Network, how can we not see its disadvantages. Following are the disadvantages of LAN:

  • The initial setup of LAN is costly in comparison to other network types.
  • Some of the communication tools in LAN networks, like switches, hubs, routers, etc., are expensive.
  • LANs are limited in size.
  • Since data is stored in a server computer, so there is a threat to security

FAQs

  • LAN full form: Local Area network while MAN stands for Metropolitan Area Network. MAN is an extended form of LAN (LAN Full Form: Local Area Network). It covers a larger geographical region than LAN. The data transfer rate of MAN is, however, considerably less than that of LAN.

  • A LAN (LAN Full Form: Local Area Network) is suitable for small area networks. It has a small geographical region which includes a building or two on the same premises, a school, college, university, an office floor or room, etc.

  • A LAN (LAN Full Form: Local Area Network) supports a high speed of data transmission to its users. The range of LAN varies from 10 Mbps to 1000Mbps (Megabits per second). LANs can extend their area up to 1km at a high data transfer speed.

  • A WAN or Wide Area Network connects computers and other LANs(LAN Full Form: Local Area Network) and MANs (MAN Full Form: Metropolitan Area Network). A WAN network is bigger than a LAN or MAN network. A WAN can be formed by connecting two or more LANs using wired or wireless media.

  • A PAN or Personal Area Network is formed by connecting a few personal devices like computers, laptops, mobile computers, tablets, etc. A PAN network can be wired or wireless. For example, a mobile phone connected to a computer through a data cable is a wired connection, and Bluetooth is a wireless connection.
