Answer:
A computer network is two or more computers which are able to communicate with each other, trade data and files, and/or share resources. The advantages to using a computer network are easy to understand when you picture a business office with multiple departments. An accountant on the 2nd floor can simply e-mail or fax a report to his/her manager on the 4th floor. Without a computer network in place, the accountant would have to print a copy of the report and deliver it by hand to his/her boss.
The internet itself is - at its simplest level - a massive collection of computer networks. Basically everything we know about the internet and how we use it today is based on computer networking.
There aren’t many disadvantages to computer networks, but there are a few. Privacy is one concern - network equipment needs to be configured properly in order to be safe from outside probes. Planning and building networks also requires time and money. The amount of time and money you’ll spend developing a network is directly correlated to how large and how sophisticated your network is. Routers, switches, cabling, workstations, servers, etc. all need to be bought and implemented correctly for the network to function…which usually requires hiring an IT professional, which then adds to your expense.
