Multiprocessing vs. Multithreading

The difference between multiprocessing and multithreading is that multiprocessing is the process that adds CPU’S to power whereas multithreading is the process that creates multiple threads of the single process that add more power to the computer.

Multiprocessing vs. Multithreading

Two most important concepts in computer science are multiprocessing and multithreading. Multiprocessing is the process that adds CPU’S to power whereas multithreading is the process that creates multiple threads of the single process that add more power to the computer. The work of multiprocessing and multithreading is to add more power to the computer. The consumption of memory by any processing effect the power of the computer, by using the techniques of multiprocessing and multithreading the efficient use of computer power is made. The system that has more than one processor is known as a multiprocessing system. More than two processors are added to increase the power of computer. CPU has set of registers the process is stored in these registers. For example, if the process of addition of two numbers is made the integers will be saved in registers and the addition of number is also stored in a register. If there will be more than one process, there will be more registers than if one processor will do work and other will be free in this way power of the computer is increased.

There are types of processors such as symmetric multiprocessing and asymmetric multiprocessing. If we talk about symmetric multiprocessing, in symmetric multiprocessing the processor is free to run and can run any process whereas in the case of multithreading there is a master-salve relationship. In multiprocessing, there is an integrated memory controller that job of the integrated memory controller is to add more memory. In multithreading, multiple threads are created.  A thread in multithreading is a process means a code segment of a process. A thread has its own thread ID, program counter, registers and stack. If we create separate processes for each service, then each processor share code, data and system resources. If we do not create threads, the system can get exhausted. Creating threads can make processor easy for working. The responsiveness is increased in multithreading, and this is the best advantage of using multithreading. The big advantage of multithreading is resource sharing and in resource sharing the several threads of a process share same code.

The system that have more than one processor is known as a multiprocessing system. More than two processors are added to increase the power of computer.

Key Differences

  1. Multiprocessing is the process that adds CPU’S to power whereas Multithreading is the process that creates multiple threads of single process that add more power to the computer.
  2. In multiprocessing processes are executed concurrently whereas in multithreading only one process is executed.
  3. Multiprocessing is not as economical as compared to multithreading whereas multithreading is economical as compared to multiprocessing.
  4. Classification of multiprocessing is systematic and a systematic processing whereas multithreading is not classified.
