Write a short note about process.
Unceremoniously, a process is a program in implementation. A process is too much than the program code, which is occasionally known as the text section. It is as well includes the current activity, as signifies by the value of the program counter and the contents of the processor's registers. Additionally a process generally includes the process stack which contains temporary data as well as a data section which contains global variables.
A program by itself isn't a process a program is a passive entity, for example the contents of a file stored in a disk, while a process is an active entity, with a program counter identifying the next instruction to execute and a set of associated resource.

Additional Reference bits algorithm Here we keep an 8-bit byte for every page in memory. At standard intervals the reference bit is shifted by the OS. If a shift register conta
Priority Scheduling leads to the risk of starvation: a process is ready, but never is given the processor. Some preemptive priority schedulers therefore reserve a fraction of the p
