Computer operators oversee mainframe computer systems, monitor their operations, and coordinate their use. They generally work in large public and private-sector organizations that use mainframe computers.
As a computer operator, you are responsible for the smooth functioning of the system in your charge, ensuring that it remains available to its users. You load tapes and disks onto the drives and make sure that the paper is fed into the system. In addition, you must constantly monitor the system database, clearing it of unneeded data. To do so effectively, you must know what information is required, what can be erased, and what should be put into backup files.
Your other duties may include introducing new users to the system, troubleshooting, and programming the system to help it function more efficiently. Though you do much of the work independently, you must be able to communicate quickly and clearly with technical support people when problems arise.
Demand for traditional mainframe computer operators is decreasing since personal computers are taking over many of the functions that used to be performed on mainframes. Also, mainframes are being linked together in networks that require a set of skills that are different from those of a traditional computer operator. However, as the impact of computers on our society grows, employment opportunities in this field will continue to expand.
The computer field as a whole offers tremendous prospects for those with the right skills and training. If you succeed as a computer operator, you may have the opportunity to advance to systems manager.
In performing this job you may either be paid a salary or receive an hourly wage.
Your biggest challenge will be to keep up-to-date with developing technology. At present, many large computers are being combined into networks. Computer operators are being replaced by network administrators who are able to link users into a network and make its resources available to them.
Network administration calls for more active involvement with a system. It also demands a wider range of computer skills. Knowledge of software packages, maintenance, programming, and the ability to teach new users how to operate a network are all required.
Working with a mainframe system can be noisy and the duties tend to be repetitive. You must be flexible about your working hours as most systems require round-the-clock monitoring. As a computer operator, you can count on doing shift work.
Monitoring a system is largely an independent occupation, but introducing new users or working with technical support demands good communication skills. You must be well organized and attentive when monitoring the functions and updating the information on a system.
If you have your sights set on becoming a network administrator, you must be resourceful and adapt easily to the evolving technology. The influence of computer networks is increasing, so it is up to administrators to recognize new opportunities and take the initiative to develop them.
Training for this position tends to be on-the-job since most computer operations are specific to a company or department. In some cases, brief introductory courses may be provided. Generally, your employer will give you time to become familiar with the system.
Network administrators should have a college diploma or university degree in computer science.
In some cases, colleges may be eliminating courses that deal specifically with computer operation and replacing them with programs that reflect the needs of today's job market.
