What is the title of the person in an organization responsible for the setup and operation of networks?

The title of the person in an organization responsible for the setup and operation of networks is referred to as a network administrator. This role typically involves installing, configuring, monitoring, and maintaining an organization's networking hardware and software to ensure optimal performance.

Network administrators manage network operations such as troubleshooting issues, implementing security measures, and ensuring that the network infrastructure meets the needs of the organization. They often work closely with other IT staff, including network engineers and architects, to deploy and maintain the organization’s networks effectively. The responsibilities of a network administrator include regular network performance monitoring, responding to connectivity issues, and performing routine maintenance tasks.

While other titles like network architect and network engineer also pertain to networking, they focus on different aspects of network design and implementation rather than the ongoing management and operation, which is the primary responsibility of a network administrator.
