Network administrators can be employed in any size of business that uses a computer network. Smaller companies, however, may rely on a local networking company rather than having their own full-time staff. In many larger companies, there may be network professionals whose time is dedicated solely to the functioning of the network. In small to mid-sized companies, network administrators often manage not only the network but may also find themselves doing PC repair, upgrading, and training. Unfortunately, network administration is not without its stresses.
Most companies rely on networks for everything from printing to Internet access.
If a network goes down, often times so does the business. To some businesses, such network disruption is an inconvenience, but to other companies, a non-functioning network can be a devastating financial blow. In either case, network administrators will be getting a call, and will be expected to be a swift and effective resource in what can be a troubling time. It is not just about fixing problems, however. Long hours on weekends and evenings are sometimes required to upgrade networks or to maintain them in an effort to keep them up and running.
