All hardware systems that support a computer network are under the control of a computer operator. Prior to the introduction of personal computers and their subsequent popularity, a computer operator’s job entailed maintaining the mainframe to which the company’s computers were connected. Because personal computers are generally self-contained, a computer operator’s job now primarily entails database maintenance and network and user support. A computer operator can work in almost any industry that uses computers, but the retail, commercial, administrative, educational, and government sectors are the most common.
A computer operator checks all connections on a network of computers on a regular basis to keep it running smoothly. USB ports, modular phone connectors, and electrical outlets are all common connections. These can be found on modems, keyboards, monitors, printers, and other peripherals that offer improved performance. Lab equipment, medical diagnostic machines, digital copying devices, and photo imaging tools may be included in the peripherals, depending on the type of business where the operator works.
A computer operator typically performs cursory performance checks of monitors, keyboards, and printers in addition to securing all hardware connectors. With his experience, he can usually spot any flaws in these devices with a quick glance. An experienced operator can quickly resolve the majority of these minor issues. Computer malfunctions that are outside of his expertise are usually reported to a computer maintenance technician.
A computer operator usually focuses on computer hardware operations and maintenance, as software issues are usually handled by another specialist. The operator, on the other hand, usually performs routine maintenance procedures to keep the computer systems running smoothly. Although many of these system checks can be scheduled to run without prompting, it is usually a good idea to check the results of the scans on a regular basis.
Firewalls should be checked regularly because damage or malfunction can expose computers to worms and viruses. Anti-spam and anti-phishing programs must be updated on a regular basis to keep the systems secure. Disk cleanups and defragmentation tools keep systems running quickly and efficiently. Another maintenance task that helps software run more smoothly is removing programs that are no longer needed or wanted.
This position requires a high school diploma or equivalent. Although a bachelor’s degree in computer science is preferred, many employers will accept an associate’s degree or a certificate of completion in computer science or computer operations. Computer, peripheral, or data processing equipment maintenance experience is generally preferred.
