7. Disadvantages of a network
Some key points
Networks can be expensive to set up. They often involve taking up floors and ceilings to lay hundreds of metres of cables
The File Server needs to be a powerful computer, which often means that it is expensive.
Networks are vulnerable to security problems. Hackers, disgruntled employees or even competitors might try to break into the system to read or damage crucial information. Much effort is spent preventing unauthorised access to data and software.
If the main File Server breaks down, then the whole system becomes useless and no-one can carry on working.
Because networks are often complicated, they need expensive expert staff to look after them.
As the number of users increase on the network, the performance of the system can be affected and things start to slow down.

On the whole, the advantages of networks outweigh the disadvantages. This is why they are so commonly found in schools, offices and factories. Even home users are starting to use networks to connect PCs around the house.
