What role does a network administrator serve in an organization?

A network administrator plays a critical role in ensuring that an organization's IT infrastructure runs smoothly and efficiently. This involves maintaining and managing both network hardware—such as routers, switches, and firewalls—and network software, including operating systems and applications that support connectivity and communication.

Their responsibilities often encompass monitoring network performance, troubleshooting issues, ensuring network security, and implementing upgrades or changes as necessary. By handling these tasks, the network administrator helps maintain optimal performance levels, facilitating seamless data exchange and connectivity within the organization. This support is vital for all business operations, as it ensures that resources are accessible and that users can effectively communicate and collaborate.

While the other roles mentioned are important in their respective fields, they do not align with the specific responsibilities and functions that a network administrator performs within an organization.
