Computer networks are critical parts of almost every organization. Network and computer systems administrators are responsible for the day-to-day operation of these networks. They organize, install, and support an organization’s computer systems, including local area networks (LANs); wide area networks (WANs), network segments, intranets, and other data communication systems.
If you choose an educational/career pathway as a systems administrator you will work with the physical computer networks of a variety of organizations and therefore are employed in many industries, including educational institutions, hospitals, banks, large corporations, and government agencies. You might also work for information technology (IT) firms.
