 LAN ( Local Area Network)

A Local Area Network (LAN) is a group of computer and peripheral devices which are connected in a limited area such as school, laboratory, home and office building. It is a widely useful network for sharing resources like files, printers, games, and other application. The simplest type of LAN network is to  connect computer and a printer in someone home or office. LAN will be used as one type of transmission medium.

It is a network which consist of less then 5000 interconnected device across several buildings.

CHARACTERSTIC OF LAN

Here are important characteristics of  LAN network:-

1. It is a private network, so an outside regulatory body never controls it.

2.LAN operates at a relatively higher speed compared to other WAN system. 

3. There are various kind of media access control method like token ring and ethernet.

ADVANTAGE OF LAN

Here are benefits of using of using LAN:-

1. Computer resource like hard-disk, DVD-ROM and  printers can share Local Area Network. This significantly reduces the cost of hardware purchases.

2. You can use the same software over the network instead of purchasing the licensed software for each client in the network. 

3. Data of all network users can be stored on a single network hard disk of the server computer.

4. You can easily transfer data and message over networked computers.

5. It will be easy to manage data at only one place, which makes data more secure. 

4. Local Area Network offers the facility to share a single internet connection among all the LAN users. 

DISADVANTAGES OF LAN 

Here are important cons/drawbacks of LAN:

1. LAN will indeed save cost because of shared computer resources. But the initial cost of installing Local Area Network is quite high. 

2. The LAN admin can check personal data files of every LAN users, so it does not offer good privacy.

3. Unauthorized users can access critical data of an organization in case LAN admin is not  able to secure centralized data repository.

4. Local Area Network requires a constant LAN administration as there are issues related to software setup and hardware failures.
