Introduction In traditional operating systems, processes have independent memory address space and a thread for control. However, in more cases, multiple threads Must be concurrently executed in the same address space. Therefore, threads are introduced into the operating system. Why thread? If it is necessary to say why a thread is needed, it is better to say wh

Operating System Concepts Learning note 15 memory management (i) backgroundMemory is the center of modern computer operation. Memory has a very big group of words or bytes, and each word or byte has its own address. The CPU extracts instructions from memory based on the value of the program counter (PC), which can cause further reads and writes to a specific memory address.A typical instruction execution cy

1. What is computer performanceThe so-called computer performance (performance) usually refers to the speed of the computer, which is the reciprocal of the program execution time. The program execution time refers to the waiting time after the user sends a task to the computer until he gets the result he needs. Including:1. time to access disk and access storage2.CPU operation Time3.I/O Action Time4. operating sys
