A network administrator is responsible for keeping an organization’s computer network up-to-date and operating as intended. Any company or organization that uses multiple computers or software platforms needs a network admin to coordinate and connect the different systems. In smaller organizations, the terms “network administrator” and “systems administrator” are often interchangeable as they cover the same tasks. However, differences between network and systems administrators become much clearer in large organizations when tasks and duties are more clear-cut.

What are the job duties of network administrators?

Here are some general tasks that network admins undertake - we've bolded the action verbs to help you determine if these are tasks you'd enjoy doing (taken directly from Onetonline.org):

• Diagnose, troubleshoot, and resolve hardware, software, or other network and system problems, and replace defective components when necessary.
• Configure, monitor, and maintain email applications or virus protection software.
• Operate master consoles to monitor the performance of computer systems and networks, and to coordinate computer network access and use.
• Monitor network performance to determine whether adjustments need to be made, and to determine where changes will need to be made in the future.
• Plan, coordinate, and implement network security measures to protect data, software, and hardware.
• Analyze equipment performance records to determine the need for repair or replacement.
• Confer with network users about how to solve existing system problems.
• Recommend changes to improve systems and network configurations, and determine hardware or software requirements related to such changes.
• Design, configure, and test computer hardware, networking software and operating system software.
• Perform routine network startup and shutdown procedures, and maintain control records.
• Load computer tapes and disks, and install software and printer paper or forms.
• Train people in computer system use.
• Maintain logs related to network functions, as well as maintenance and repair records.
• Gather data pertaining to customer needs, and use the information to identify, predict, interpret, and evaluate system and network requirements.
• Coordinate with vendors and with company personnel to facilitate purchases.
• Implement and provide technical support for voice services and equipment, such as private branch exchange, voice mail system, and telecom system.
• Maintain an inventory of parts for emergency repairs.
• Research new technologies by attending seminars, reading trade articles, or taking classes, and implement or recommend the implementation of new technologies.

What is a typical day like for a network administrator?

Typical days don't really exist for network administrators! A “normal day” might include checking logs, auditing processes, putting out fires that arise from your end users and working on projects. Projects could include automating routine daily processes or researching technology and brainstorming creative solutions for the organization’s network needs.

Network administrator work hours are another factor to consider—it’s fairly common for network admins to regularly work in excess of 40 hours per week, and some may work “on call” where they can be asked to work outside of regular hours in case of emergency.
