What Does a Computer Networker Do?
A computer network is essential to every office, business, or institution in the modern, technology-driven world. A computer networker uses his or her knowledge and understanding of these systems to fill an important role in the function of any institution. Schools offering Cisco Network Systems degrees can also be found in these popular choices.
A computer network exists whenever two or more computers are linked together to share data. The actual sharing of this information can require the management of a wide variety of both computer hardware and software. Local area networks (LANs) may be wireless or wired; likewise, wide area networks (WANs). The wireless application is becoming increasingly popular; however, a computer networker should be knowledgeable about all types of systems. The networks themselves can be extremely complex, but a rough classification might be as follows:
- Local Area Network (LAN) - operates within restricted area.
- Wide Area Network (WAN) - operates across cities, countries, or the world.
- Wired - uses cables for communication between computers.
- Wireless - uses radio waves or microwaves to communicate.

Training and Education
Training in computer networking can begin in high school. Students at that level can start to learn the basics of configuring routers, installing wires and working with a variety of operating systems and protocols. Following that, there are focused two-year programs that offer not only basic networking skills but on-the-job experience. Then there are four-year degree programs that require a greater investment of time and money, but also offer greater long-term prospects.
