definition :- operating system is a software program located between the computer user and acts as an interface between the application program and the computer hardware.

Generation of operating system

first generation(1940-1956) vacuum tubes
-used vacuum tubes for circuitry and magnetic drums for memory.
-taking up entire rooms.
-very expensive to operate.
-computer relied on machine language.
-in addition to using a great deal of  electricity , generated a lot of heat , which was often the cause of malfunctions.
-the lowest level programming language understood by computer to perform operation and they could only solve one problem at a time.
-inputs are based on punched cards and paper tape and output was displayed on printouts.
E.G.:- UNIVAC and  ENIAC computer.
