A degree in computer networking will give you the knowledge on how to maintain, build, manage and repair computer network systems. As a computer network specialist, it will be your responsibility to take care of large or small network systems. A computer network is the way in which groups of computers, either on a small scale, or on a large scale spanning numerous cities, communicate with one another. A degree will teach you the intricacies of how computer users are able to share resources and data. You will also learn how to keep those systems working smoothly and safe from external threats to the network.
