Multi User Operating Systems

An operating system is a set of software programs, which manage computer hardware in a controlled fashion. The operating system controls the file-system, process management, memory management and peripherals. Multi-user operating systems are used on large mainframe computers. A mainframe computer system has one very powerful processing unit, which may contain many microprocessors. Many users will all share this processing unit. They use terminals (a keyboard and a monitor) to access the mainframe computer. A multi-user operating system lets more…...

History and development of Operating Systems

At first, computers lacked any form of operating system. The computer user had sole use of the machine. The user would arrive at the machine armed with his or her program and data, often on punched paper tape. The program would be loaded into the machine, and then the machine set to work, until the program stopped. Later, computers came with libraries of support code which were linked to the user's program to assist in operations such as input and…...
