INSTRUCTION EXECUTION Meaning and
Definition
-
Instruction execution is the core process in computer programming that involves the completion of individual instructions or commands by a computer's central processing unit (CPU). It refers to the series of steps taken by the CPU to read, interpret, and carry out the instructions written in a computer program.
During instruction execution, the CPU fetches the next instruction from memory, decodes it to understand its meaning, retrieves the necessary data from memory or registers, performs the required calculations or operations, and then stores the result back in memory or registers. This process is repeated for each instruction in the program until all instructions have been executed.
The execution of instructions is typically guided by the control unit of the CPU, which coordinates the flow of instructions and data within the computer. The control unit determines the sequence in which instructions are executed, ensuring that they are performed in the correct order and that any dependencies between instructions are properly managed.
The speed and efficiency of instruction execution can greatly impact the overall performance of a computer system. Therefore, modern CPUs often incorporate advanced techniques such as pipelining and caching to optimize the execution process and minimize the time required to complete instructions.
In summary, instruction execution refers to the process by which a computer's central processing unit reads, interprets, and carries out the individual instructions or commands specified in a computer program. It involves fetching, decoding, executing, and storing the results of each instruction in a systematic and controlled manner.

Etymology of INSTRUCTION EXECUTION
The word "instruction execution" does not have a specific etymology as it is a combination of two commonly used words in the field of computer science.
The term "instruction" comes from the Latin word "instructio", which means "teaching" or "instruction". It refers to a specific command or directive given to a computer to perform a certain operation.
The word "execution" comes from the Latin word "executio", which means "carrying out" or "performing". In the context of computer science, it refers to the process of carrying out the instructions given to a computer by actually performing the desired operations or tasks.
So, the term "instruction execution" simply combines these two words to describe the process of a computer carrying out or performing a specific command or directive.
