What are the threats for operating system security?
threat is a unit of code....and a process can have ine or more threats..process is an execution of a programe
What is Program execution in operating system?
Program Execution means that you open or run a program installed at the computer. my question how to do program execution
Which Software loads the operating system into memory before execution?
bootstrap
Is an operating system a system software?
Yes, an operating system is system software. It is software that controls the execution of computer programs and provides an interface between those programs and the hardware of the computer.Yes, an operating system is software.
What are four resources required for process execution?
various CPU registers where process need to be stored for execution for running state.process priority and other scheduling information which is required to schedule the information of page table.memory limitssegment table depending on the memory used by the operating system

Is system operation is the process of operating system?
Process is a programm under execution in main memory. Or in other world when a user wants to execute a programm which resides on secondary memory it must be placed in to the primary memory for the execution then it is called as process.
What is the significance of ''process''in an operating system environment?
Process is a programm under execution in main memory. Or in other world when a user wants to execute a programm which resides on secondary memory it must be placed in to the primary memory for the execution then it is called as process.
What is pseudo-parallelism in context process implementation?
At a particular time either a user program is running or operating system is running.
What is burst time?
In an operating system, burst time refers to the time that it takes to complete execution of a particular task or process. It is used in CPU scheduling.

What is the context switch in UNIX?
Context switching is, as far as I know, essentially the same process in all multi-tasking operating systems.Simplistically, in order for a multi-tasking operating system to switch tasks on and off a CPU, the operating system must be able to store and restore the state of the CPU for each process that shares that CPU. The act of storing and restoring the CPU state is referred to as context switching.In a nutshell (an oversimplified nutshell), the states/values of the Instruction Pointer, the registers, accumulator etc. must all be saved for a given process for the OS (Operating System) to move to the next process in the queue. Once they are saved, the states/values of the next process in the queue can be loaded into those same registers etc. and that process can continue execution for 'N' number of instructions. Then this whole procedure is repeated for the next process in the queue. And so on, and so forth, ad infinitum...Necessarily, MUCH is omitted in the above over simplification but it is hoped, none the less, that the above description provides some very general idea of what happens during a context switch.The term context switching is a sort of catch all which may refer to and cover a number of more specific processes such as thread context switches, register context switches, task context switches etc.This answer is necessarily over simplified as a full description of context switching is far beyond the scope deemed acceptable in this forum.
What is the difference between a computer and an operating system?
a computer is a machine for performing caculations automatically while an operating system is a software that contrls the execution of a computer
Concurrent process uses of operating system?
processes are concurrent if they exist at the same time.concurrent process can function completely indepently to one another. two process are concurrent if their execution can overlap in time; that is, the execution of the secon process starts before the first process completes. concurrent processes generally interact through the following mechanisms: Shared variables Message passing
