Chapter 1: Problem 17

When a CPU executes the instructions in a program, it is engaged in what process?

Short Answer

Expert verified

Answer: The CPU engages in the Instruction Cycle process when it executes the instructions in a program.

Step by step solution

Understand CPU and Program Execution

To answer this question, we first have to understand what a CPU (Central Processing Unit) is and its role in the execution of instructions in a program. A CPU is the primary component of a computer that performs most of the processing inside the computer. It interprets computer program instructions and performs tasks such as arithmetic, logical, and input/output operations.

Identify the Process when CPU Executes Instructions

When a CPU executes the instructions in a program, it follows a specific sequence of steps: fetching, decoding, executing, and storing (also known as writing back). These steps are repeated until the entire program has been executed. The process of fetching, decoding, executing, and writing back instructions is called the

Instruction Cycle

or the Fetch-Decode-Execute Cycle. So, when a CPU executes the instructions in a program, it is engaged in the Instruction Cycle process.
