Which role typically involves maintaining and supporting IT systems?

The role that typically involves maintaining and supporting IT systems is that of a Network Administrator. Network Administrators are responsible for the set up, administration, and troubleshooting of network infrastructures. Their core duties include ensuring the reliability, security, and efficiency of network communications, managing user access, and maintaining network performance.

While Computer Programmers focus on writing and debugging code for applications and software, and System Analysts analyze and design information systems to meet business needs, their roles do not emphasize the ongoing maintenance and support of IT systems. Data Encoders, on the other hand, primarily handle the input and management of data over systems but do not typically engage in system maintenance or support tasks.
