stored program

Thân thiện

A computer runs a stored program to calculate a simple equation.

Definition

Noun: A stored program is a set of instructions for a computer that is held within the computer's own memory. This allows the computer to read and execute the instructions directly from its memory, enabling it to perform tasks and run software.

Usage

The term "stored program" is used to describe the fundamental architecture of modern computers, where both the data and the instructions (the program) are kept in the same memory system. This concept is central to how computers operate.

Examples

• The invention of the stored program concept was a major breakthrough in computing history.
• In a stored program computer, the central processing unit (CPU) fetches instructions from memory one by one to execute them.
• Early computers required physical rewiring to run different tasks, but the stored program model made software possible.

Advanced Usage

• Stored-program concept/architecture: This refers to the overall design principle where instructions are stored in memory. It is often credited to John von Neumann.
  • The von Neumann architecture is based on the stored-program concept.

Variants and Related Words

• Stored-program computer (n): A computer designed around the stored program concept.
  • Modern personal computers are examples of stored-program computers.

Synonyms

• Internal program
• Memory-resident program

Notes

The "stored program" is a foundational concept in computer science. It distinguishes modern, general-purpose computers from earlier fixed-function calculators or machines that were programmed via physical switches or punched paper tapes.
