Computer Architecture Questions
Multiprogramming and multitasking are both techniques used in computer systems to improve efficiency and utilization of resources.
Multiprogramming refers to the ability of a computer system to execute multiple programs concurrently. In multiprogramming, multiple programs are loaded into the main memory simultaneously, and the CPU switches between them to execute instructions. This allows for better utilization of the CPU and reduces idle time.
On the other hand, multitasking refers to the ability of an operating system to execute multiple tasks or processes concurrently. In multitasking, a single program is divided into smaller tasks or processes, and the CPU switches between them rapidly, giving an illusion of parallel execution. This allows for better responsiveness and user interaction, as multiple tasks can be performed simultaneously.
In summary, the main difference between multiprogramming and multitasking is that multiprogramming involves executing multiple independent programs concurrently, while multitasking involves executing multiple tasks or processes of a single program concurrently.
