How Operating System Program Run
. An operating system program is loaded in the computer memory which starts to run when the computer is switched on. Operating system is a medium to use the resources of computer system such as store a data, run a program, input-output system.
To run this operating system when the computer starts, a bootstrap program is stored in ROM.
This bootstrap program extracts the program in operating system and runs on the memory which keeps on running until the power is on.
Time-sharing /Multi-programming system
a) In an operating system, one and more than one program can run. However, only one program can use the resources of CPU at a particular time, whereas other program are in stand-to access the CPU.
b) This condition applies for the single user in an operating system. Some systems are developed in such a way that allows more than one user to access the resources of CPU simultaneously.
