What Are the Disadvantages of LAN?

Businesses, as well as other organizations, often link their computers together to make communication more efficient, for which they utilize LAN (Local Area Network). Each computer would be linked to a central server which acts as a go-between within this LAN as well as beyond. Before we go through the Disadvantages of LAN, it is required to discuss some of their advantages also. So, before we learn more about the disadvantages of LAN, if you are desiring to obtain any Cisco Certification, SPOTO would be the best institution for you.

Advantages of LANs:

Here are certain Advantages of LANs:

•    A central backing store could be provided in one place so all your work would be saved together. An individual user could load his or her work on any computer on the network.

•    The software could be shared, as well as upgraded is quite easier too. This would give you continuity in the workplace. However, sharing software is considered to be often not much cheaper than providing a copy for each machine because a license has to be bought for each copy of the software needed.

•    Central back-up could take place automatically at regular intervals. A user would usually be able to retrieve work that has been deleted by mistake.

•    Data could be shared across the network, through LAN. For example, this would allow several people so as to work on the same project. The setting up of hierarchical system passwords in order to allow different users different access is considered to be the key to controlling access to most company databases.

•    Local email messages could be sent to people who are working at other terminals on the network. This could save time as well as ensures that messages would be received to the right place.

•    There might be a local Intranet. But it works as the World Wide Web, with pages of information. The difference is that the pages which could be accessed only over the LAN. As it doesn’t involve phone links, an Intranet is free.

Disadvantages of LANs:

•    The use of email within the network could lead to problems of time-wasting as people would send messages that don’t relate to work. Some companies discourage the use of in-house email because they believe that it is considered to be better for employees to communicate face to face.

•    Where a lot of terminals would be served by only one or two printers, long print queues might develop, causing people to have to wait for printed output. Rings would be provided as the fastest form of local area networking.

•    Network security could be a problem. If a virus gets into one computer, it would likely to spread quickly over across the network because it would get into the central backing store.

•    Users of the network have to have user names as well as passwords. Some users are not quite good at keeping passwords secret, or they might use passwords that could be easily guessed. Other people could then log onto the network.

•    If the dedicated file server fails, work stored on shared hard disk drives wouldn’t be accessible and it won’t be possible to use network printers either.

•    Cabling could be quite expensive to buy and to install. In a busy office situation, cabling must often be placed under the floor so that people won’t trip over it. If connecting cables would be damaged, some sections of the network could become isolated. They won’t be able to communicate with the rest of the network. 

So, if you wish to acquire more information to learn more about the LAN, you should check out the courses which are being offered at the SPOTO. As when it comes to Cisco Certification, SPOTO is the best.
