1.1 What is multithreading

The core hardware of a computer is disk, memory, CPU, disk is used to persist data, CPU is used for calculation, and memory is a buffer between disk and CPU.

Disk read and write too slow, CPU operation is too fast, if the CPU every time to disk read and write data efficiency is very low, so read and write faster memory, the CPU frequently used data read to the memory for CPU use, and so on once the CPU is used to write to the disk
