Disadvantages of LAN : Cons Limitations Drawbacks of LAN

Distributed Data: Data sharing in LAN is stored locally on each computer in the networks if a machine is not turned on, the other machines cannot navigate to the shared files on that machine is.

The safety and security is not high: The security and safety can peer through specifying the password for a certain resource, such as a shared folder on the network. Since all users in the peer network set up your own personal password system, and the sharing of resources can occur at any machine not happen in your focus, it is difficult to control focus. Moreover, the appearance of the virus spreads through the dangerous, if a machine can spread infection throughout the network, which will greatly impact to system maintenance.

No corporate governance and control users as well as manage the computers in the network.

Power - a good LAN is required to be on all the times.

Security - each computer and device become another point of entry for undesirables.

Upkeep - when things go wrong or the software gets updated.

Frustration if having a problem setting up.

A lot of times a network shares one Internet connection - if all computers running at once, can reduce speed for each.

Area covered is limited.

Special security measures are needed to stop users from using programs and data that they should not have access to.

Networks are difficult to set up and need to be maintained by skilled technicians.

If the file server develops a serious fault, all the users are affected, rather than just one user in the case of a stand-alone machine.

Wired and therefore more difficult to setup. Drilling holes in wall, running cables in lofts etc, fitting sockets and redecorating. More expensive to set up. More time consuming to set up. Not as flexible, can only use where there is a socket - cannot use outside for example.

Wired systems cannot be used in listed buildings.

Investment in Higher Costs due to server systems.

More complex governance: need for administrators to Maintain and manage networks.

Poor scalability: the number of accounts and a large number of computers will cause Difficulties in management.

The ability to Prevent attacks from the internet no less by the firewall system specific.

Investment in Higher Costs due to server systems.

More complex governance: need for administrators to Maintain and manage networks.

LAN Disadvantages: 

• Special security measures are needed to stop users from using programs and data that they should not have access to; 
• Networks are difficult to set up and need to be maintained by skilled technicians. 
• If the file server develops a serious fault, all the users are affected, rather than just one user in the case of a stand-alone machine.

There is increased of data corruption 
there is greater risk for virus
