Which profession is primarily concerned with creating and maintaining networks?

The profession that is primarily concerned with creating and maintaining networks is the Network Administrator. This role involves the responsibility for overseeing and managing computer networks, ensuring that network infrastructure operates efficiently, and providing troubleshooting support for network issues. Network Administrators are crucial in configuring, supporting, and optimizing network equipment like routers, switches, and firewalls, which are essential components of both local area networks (LANs) and wide area networks (WANs).

While other professions like Game Developers, Website Developers, and Software Developers may need to understand network principles to some degree, their main focus lies in creating software applications, games, or websites rather than directly managing network systems. Therefore, the specific responsibilities of a Network Administrator make this the correct answer for a role primarily dedicated to network creation and maintenance.
