What is the process of the computers?

Answer 1

In computing, a process is a running instance of a program, including all variables and other state. A multitasking operating system switches between processes to give the appearance of simultaneous execution, though in fact only one process can be executing at once per CPU core. A process is the active element in a computer. Terminals, files, and other I/O devices communicate with each other through processes. Thus, network communications is interprocess communications (that is, communication between processes).

Answer 2

A process is an instance of running a program. If, for example, three people are running the same program simultaneously, there are three processes there, not just one. In fact, we might have more than one process running even with only person executing the program, because (you will see later) the program can "split into two," making two processes out of one. Keep in mind that all UNIX commands, e.g. cc and mail, are programs, and thus contribute processes to the system when they are running. If 10 users are running mail right now, that will be 10 processes. At any given time, a typical UNIX system will have many active processes, some of which were set up when the machine was first powered up. Every time you issue a command, UNIX starts a new process, and suspends the current process (the C-shell) until the new process completes (except in the case of background processes, to be discussed later). UNIX identifies every process by a Process Identification Number (pid) which is assigned when the process is initiated. When we want to perform an operation on a process, we usually refer to it by its pid. Unix is a timesharing system, which means that the processes take turns running. Each turn is a called a timeslice; on most systems this is set at much less than one second. The reason this turns-taking approach

is used is fairness: We don't want a 2-second job to have to wait for a 5-hour job to finish, which is what would happen if a job had the CPU to itself until it completed.

Answer 3

in computing, a process is an instance of a computer program that is being executed. It contains the program code and its current activity. Depending on the operating system(OS), a process may be made up of multiple threads of execution that execute instructions concurrently.

A computer program is a passive collection of instructions; a process is the actual execution of those instructions. Several processes may be associated with the same program; for example, opening up several instances of the same program often means more than one process is being executed.

Multitasking is a method to allow multiple processes to share processors (CPUs) and other system resources. Each CPU executes a single task at a time. However, multitasking allows each processor to switch between tasks that are being executed without having to wait for each task to finish. Depending on the operating system implementation, switches could be performed when tasks perform input/output operations, when a task indicates that it can be switched, or on hardware interrupts.

A common form of multitasking is time-sharing. Time-sharing is a method to allow fast response for interactive user applications. In time-sharing systems, context switches are performed rapidly. This makes it seem like multiple processes are being executed simultaneously on the same processor. The execution of multiple processes seemingly simultaneously is called concurrency.

Answer 4

Pretty easy, it is a program that runs on background and could be an application that you are running right now. It is just a program or a exe file.

Answer 5

Computers are capable of doing many different tasks. For instance they can store information, make advanced calculations, and connect to the internet.
