CPU-based computer system architecture
Processor-based computer systems can include Single Processors or Multi Processors. In a single processor, the processor allows the processor to be shared across multiple processes by switching the processor between processes. The processor switch speed is so high that the user is not aware of it. This is what they call congruence.
Concurrency means that one processor can perform multiple processes. The kernel uses an algorithmic operating system for this purpose. There are various algorithms for running processes and switching them between CPUs, each of which has its own algorithm.
Multiple processors can run multiple processes in parallel. Parallel processing speeds up execution. For high computational areas such as matrices or data processing, a multiprocessor system will work. All the work is done on different processors and then the final answer is obtained by gathering all the answers.

In single-processor all memory is the same as single-processor but in multi-processor the memory is shared either by all processors or in a private way for each processor. The multiprocessor system, which is shared among all processors, is called Symmetric Multi Processing (SMP), and the multiprocessor system, each of which has its own private memory, asymmetric multiprocessor systems. (Asymmetric Multi Processing or AMP).
