This action is not available.
A computer operator is the person who keeps the large computers running. This person’s job is to oversee the mainframe computers and data centers in organizations. Some of their duties include keeping the operating systems up to date, ensuring available memory and disk storage, and overseeing the physical environment of the computer. Since mainframe computers increasingly have been replaced with servers, storage management systems, and other platforms, computer operators’ jobs have grown broader and include working with these specialized systems.
