Computer network installation has become an essential prerequisite for any efficient modern-day business as it allows employees to truly work as a team by sharing information, accessing the same database and staying in touch constantly
Corporations and businesses use computer networks in daily functions, making the jobs of computer network engineers important for keeping these networks in good operating condition. Computer network engineers are prepared for a variety of duties involved in designing new computers, testing computers, and maintaining existing computer network systems
A network is simply a means for computers to speak to each other, or communicate with each other. With a network, computers can receive emails from each other, send files to each other, instant message each other and a variety of other things. This is something that we take for granted today but there was a time when networks were not so sophisticated and not all that efficient either
The more common type of LAN connection is client server. This is where all the computers in the network are connected to each other via a central computer. This kind of connection does require more work in set up but is more efficient, carries data better and if one computer goes down the others aren't affected. However, should the server go down then all the computers on the network would be affected as far as their ability to get information from the other computers and the server itself. They, however, would still be able to do work locally on their own such as with a word processing program, unless the word processing program was located on the server. Then it would not be available. Usually, however, most applications are installed on each computer. What is most commonly lost when a server goes down is the ability to retrieve data that is common to everyone in the network, say an in house database of all employees
