What are the Advantages and Disadvantages of LAN in Computer Network?

Following are the advantages and disadvantages of LAN −

There are various advantages of LAN, which are as follows −

Inexpensive transmission media.
It can simplify the physical association of a device to the media.
It is used to high data transmission rates.
Network data transmission is independent of the connected devices rates, making it accessible for the one-speed device to send data to another speed device.
A large rate of interconnection between devices.
Each connected device has the potential to interact with another device on the network.
It is flexible and growth-oriented.
It allows file locking.
It provides full proof of the security system against illegal access to data.
LANs are a productivity tool. In the case of business, a LAN should be an apparent contributor to raised profitability.

There are various disadvantages to LAN, which are as follows −

LAN software needed a memory area in each of the mainframe used on the network. This decreases the memory space available for the user’s program.
Local area networking adds another phase of difficulty to the computer operation. Users can have a problem in understanding the network commands. The installation and authority of a LAN require far more technical and regulatory skills than installing and handling multiple computers that are not networked.
Some security system should be executed if it is essential to protect private data.
Some control on the part of the customer is lost. We have to share a printer with different customers.
Some current application programs will not run in a network environment.
