Multiprocessing and multithreading are techniques used to enhance application performance through parallel execution. They help systems handle multiple tasks efficiently by utilizing CPU resources effectively.
- Enable faster execution of tasks.
- Improve overall system performance.
- Support parallel processing of tasks.
Multiprocessing
Multiprocessing is a system that has more than one or two processors. In Multiprocessing, CPUs are added to increase the computing speed of the system. Because of Multiprocessing, There are many processes are executed simultaneously. Explore more about similar topics.
Multiprocessing is classified into two categories:
- Symmetric Multiprocessing
- Asymmetric Multiprocessing
Advantages
- Increases computing power by utilizing multiple processors.
- Suitable for tasks that require heavy computational power.
Disadvantages
- Process creation is time-consuming.
- Each process has its own address space, which can lead to higher memory usage.
Multithreading
Multithreading is a system in which multiple threads are created of a process for increasing the computing speed of the system. In multithreading, many threads of a process are executed simultaneously and process creation in multithreading is done according to economical.
- Multiple threads run within the same process
- Shares memory, so communication is faster
Advantages
- More efficient than multiprocessing for tasks within a single process.
- Threads share a common address space, which is memory-efficient.
Disadvantages
- Not classified into categories like multiprocessing.
- Thread creation is economical but can lead to synchronization issues.
