Programexekvering
Programexekvering, also known as program execution, is the process by which a computer or other programmable device carries out the instructions contained within a program. This process begins when a program is loaded into the computer's memory. The central processing unit (CPU) then fetches instructions one by one from memory and decodes them to understand what action needs to be performed. Once decoded, the CPU executes the instruction, which might involve mathematical calculations, data manipulation, or input/output operations. This cycle of fetching, decoding, and executing repeats until the program is completed or an error occurs.
During execution, various components of the computer system interact. The CPU performs the core computations, while
