What is the advantage and disadvantages of computer network and communications?
The main advantage of a network is that computers can share information. A computer network can store more data than a stand-alone computer. This is great if you have a business because your employees can exchange vital information easier. The main disadvantage would be security concerns, i.e. someone hacking into your network. However, you can buy software and hardware to help prevent this. Just remember that any protection you get can be broken if the hacker has enough time and patience.
