Introduction of LAN Network

LAN stands for “Local Area Network“. LAN meaning that it works as privately network because LAN is a bunch of computer machines and other connected nodes, and they can transfer data in between entire network. Local area network is developed to operate over small region like as shopping mall, office, campus etc. Main objective of using of LAN is to share resources (printer, FAX machine, plotter etc.) with multiple computers and swap data.


Advantages and Disadvantages of LAN

In this section, we will guide you properly about many advantages and disadvantages of LAN network | benefits and limitations of LAN (Local Area Network); below shown all, you can check them:

Advantages of LAN (Local Area Network)

There are various benefits of LAN network, below explain each one:–

Resource Sharing: LAN offers to great facility resource sharing such as printer, modem, plotter, scanner, and more.

Software Program Sharing: LAN allows to use single software program with multiple computer that are linked in computer network. So, no need to buy separate licensed application program for every client machine.

Simple and Fast Communication: In Local Area Network (LAN), huge data and other types of messages can simply be shared with another linked computer terminal over network.

Cost-Effective: Local Area Network (LAN) is cheapest to setup and maintain compare to other like WAN and MAN, because in LAN system no need to large cabling and other infrastructure. Due to local nature of LAN, it gets easy troubleshooting and maintenance.

Centralized Storage: All data and messages are stored in the storage medium on centralized server machine. It allows to all users for accessing of those data on the network.

Data Protection: All data are saved on the local server computer machine, and it is not easy task to leak those data. So LAN is more protected.

Internet Sharing: Local Area Network (LAN) offers to great functionality to share internet connection with multiple LAN connected users.

Computer Identification: Every computer system has own MAC address that is stored in the switch or router during communication between multiple computers. With the help of these MAC addresses, each client machine can identify that where to send and receive all data.

Disadvantages of LAN (Local Area Network)

There are some limitations of LAN networks such as –

Limitation of Geographical Region: Local area networks are mostly bound in small area such as in small building, school, college campus etc.

Security Issue: If the centralized sever computer is not get configured properly then its data security can be loss. So intruder can take benefits and grab your data. If anyone computer get virus then it can easily replicate entire network.

Server Dependency: If anytime centralized server computer get halt, then entire LAN system can work properly. So, entire LAN network is depending on the center server machine.

Initially LAN setup is Costly: In the starting, to establish LAN network must be special type’s software like as network operating system and other network hardware components such as hubs, repeaters, switches, cables etc. So these hardware and software components of networking are costly.

Privacy Broken: LAN administrator has authority to see every data of each connected user.

Characteristics of LAN Network

  • Entire LAN setup gets small region, so it is an easy task to handle this network.
  • LAN has high speed with supporting Ethernet cables. For example – in modern Ethernet version
  • It can support speed up to Gigabit per second.
  • Some protective protocols provide excellent security from intruders.
  • Due to excellent speed, it offers to great Productivity of small or large scale organizations.
  • It is great stable network compare to other like as WAN, MAN, PAN


Now, i hope that you are completed learnt about advantages and disadvantages of LAN (Local Area Network) | Limitations & Benefits of LAN network with ease. If this article is valuable for you, then please share it along with your friends, family members or relatives over social media platforms like as Facebook, Instagram, Linked In, Twitter, and more.
