Where a program is stored and executed?

Programs are stored on secondary storage devices such as hard disks. When you install a program on your computer, the program is actually copied to your hard disk. But when you execute a program, the program is copied (loaded) from your hard disk to the main memory, and that copy of the program is executed.

Where a program is stored and executed in computer?

The CPU. The CPU is the heart of the computer. A program is a sequence of instructions stored in main memory. When a program is run, the CPU fetches the instructions and executes or follows the instructions.

Where is a program stored?

The programs are stored on the disk (or other permanent storage. It does not need to be a disk, it can be on a network or any other place such as a ROM). When you start a program the parts of it which are needed are loaded into the main memory (the RAM).

Where the programs and data are stored?

At the core of the computer is the central processing unit or CPU, the source of control that runs all programs and instructions. In order to function, computers use two types of memory: primary and secondary. The main storage is the primary memory, and data and programs are stored in secondary memory.

How are programs stored on a computer?

A stored-program computer is a computer that stores program instructions in electronically or optically accessible memory. This contrasts with systems that stored the program instructions with plugboards or similar mechanisms.

How does an operating system execute a program?

The operating system’s most important job is managing the CPU: If there are multiple programs that must execute, then it is a disaster if one program uses the processor and «loops. » The OS must ensure that all programs have fair use of the processor’s time so that all programs make progress at execution.

How a process is executed?

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

What part of a computer runs programs?

The CPU (Central Processing Unit) is that part of the computer that actually runs the programs. The CPU actually performs the execution of the instructions that are listed in the program.

Is software stored on the hard drive?

What is stored on a hard drive? A hard drive can store any data, including pictures, music, videos, text documents, and any files created or downloaded. Also, hard drives store files for the operating system and software programs that run on the computer.

Which memory is needed to execute the program?

When the CPU executes a program, that program is stored in the computer’s main memory (also called the RAM or random access memory). In addition to the program, memory can also hold data that is being used or processed by the program. Main memory consists of a sequence of locations.

Where is data stored on a hard drive?

The data is stored in a very orderly pattern on each platter. Bits of data are arranged in concentric, circular paths called tracks. Each track is broken up into smaller areas called sectors. Part of the hard drive stores a map of sectors that have already been used up and others that are still free.
