Computer Operators are also known as Computer Programmers, Computer Support Specialists, or System Administrators.

Computer operators are no wonder, the functional life buoys of the whole computer-processing unit. Akin to the role of a life buoy, these genius elves save any PC from crashing. With the help of their expert operative skills, they are literally the life-saviours of the varied computer programmes – resolving the breakdown of any computer part, removing faulty running or error messages, ensuring non-attack by viruses and if so, then devising ways of eradicating them. Thus, possessing an extensive knowledge about the assorted activities of the computer, these professionals are truly the software guardians.

Computer operators oversee the operation of computer hardware systems, ensuring that these machines are used as efficiently as possible. They may work with mainframes, minicomputers, or networks of personal computers. Computer operators must anticipate problems and take preventive action, as well as solve problems that occur during operations. The duties of computer operators vary with the size of the installation, the type of equipment used, and the policies of the employer. Generally, operators control the console of either a mainframe digital computer or a group of minicomputers. Working from operating instructions prepared by programmers, users, or operations managers, computer operators set controls on the computer and on peripheral devices required to run a particular job.

Computer operators load equipment with tapes, disks, and paper, as needed. While the computer is running—which may be 24 hours a day for large computers—computer operators monitor the control console and respond to operating and computer messages. Messages indicate the individual specifications of each job being run. If an error message occurs, operators must locate and solve the problem or terminate the program. Operators also maintain logbooks or operating records, listing each job that is run and events, such as machine malfunctions, that occur during their shift. In addition, computer operators may help programmers and systems analysts test and debug new programs. A computer programmer prepares a computer program for obtaining the required data output.

Computer Operators also process the operations of computer hardware systems, including minicomputers, networks of personal computers (PCs) and mainframes, ensuring efficient use. Others may be retrained to perform different job duties, such as supervising an operations center, maintaining automation packages, or analyzing computer operations to recommend ways to increase productivity. Checking system performances and recording of problems are also inclusive within their varied fundamental duties.

The tasks usually include -

a) Scheduling
b) Loading and downloading programs
c) Mounting tapes
d) Rerouting messages
e) Running periodic reports
f) Monitoring batch processes

In the future, operators who wish to work in the computer field will need to speciallise in:

 Programming
 Automation software
 Graphics interface
 Client/server environments
 Open system
