{{Program execution}}
'''Execution''' in [[computer engineering|computer]] and software engineering is the process by which a [[computer]] or [[virtual machine]] reads and acts on the instructions of a [[computer program]]. Each instruction of a program is a description of a particular action which must be carried out, in order for a specific problem to be solved. Execution involves repeatedly following a '[[Instruction cycle|fetch–decode–execute]]' cycle for each instruction done by [[control unit]]. As the executing machine follows the instructions, specific effects are produced in accordance with the [[Formal semantics of programming languages|semantics]] of those instructions.
