They are first employed to estimate the networking needs of a particular organization depending upon the type of work they do, the number of employees they have and the level of networking technology which would be needed by them. Once the need of the computer networks has been estimated and its type decided, network engineers then do the actual work of deploying and configuration of the computer networks. They have to design the computer network in such a fashion that it becomes convenient to use and increases the productivity and also the security of the networks have to be taken into consideration. They debug and troubleshoot the various problems affecting the network and ensure that the downtime of networks is reduced to bare minimum so that the operations of an organization are not affected.
