Essay on A Multiple User Operating System
The operating system provides the graphical user interface simplifies the use of computers for users. Operating systems can be divided into few major types that are Single User OS, Multiple User OS, Real Time OS and Embedded OS. A Single User operating system provides access to the computer system for a single user at an instant. Single user operating system provides access to one user but support multitasking. A Multiple User OS allows more than one user to access the computer system at an instant.

By 1965 the first operating system was invented, the Fortran Monitoring System that can load three types of programs, the Fortran Program, the Compiler, and the Machine language program. A tape containing the operating system is loaded first in order to start the operating system. Start-up of a computer was a long and involved process because the operating systems did not have the bootstrap mechanism. Computer companies have to support two completely different types of computers, 1401 like character based computers, and word-oriented 7094 like scientific computers. Maintenance and training on these completely different systems was problematic so IBM invented System/360 was created. The IBM 360 was the first computer line to use small scale integrated circuits and offered a major cut in price.
The multi-computing was popular, where instead of waiting for a single job, the computer could be running multiple jobs
