Several common types can be
The principle of microcomputer is only taught to non-computer majors. Most of the 8086 structure and how it works, as well as how to write assembly language.
The principle of computer organization discusses how the various parts of the computer are implemented (circuits).
Computer architecture talks about how to design computers according to different scenarios and usage situations on the basis of computer composition principles, as well as the advantages and disadvantages of various designs.
Take the cache as an example. The principle of computer composition talks about how to make a cache (four transistors of DRAM form a unit), while the computer architecture talks about how to use the cache in the CPU (multi-level cache, different levels of cache use different The addressing mode) can achieve the maximum performance, the advantages and disadvantages of different usage methods and how to compromise according to different situations in practice.
In the principle of computer composition, how to make a hard disk, the physical mechanism of magnetic head reading and writing, and how to design the disk arrangement in computer architecture can make the probability of accidental data loss meet the requirements at the lowest cost.
