University computer course review-computer composition principle

The score of the Master of Engineering at Jiaotong University is over. Let's celebrate it first. However, it is not a few days before the review. This is a professional course for the university. I will review a course every day.

Start with the computer composition principle.

Focus

1. The history of computer development focuses on the structure (operation, control, storage, input/output) of the Von norm machine ).
2. Hexadecimal conversion (generally using binary as the intermediary)
3. Various codes (the most important one is the complement code)
4. Various binary operations (mainly using the addition and subtraction of the complement code, pay attention to the overflow problem during the same number)
5. Parity (check the number of values in 1. For example, odd values in 1 are equal to 0)
6. CRC verification code
7. Memory (RAM, ROM)
8. Memory expansion (bit extension, word extension)
9. Commands (addressing)
10. Proteus
11. Microprogram composition command
12. Three-tier Storage System
13. Memory Replacement Algorithm (FIFO, LRU)
14. Segment-and-page storage (segments are prone to fragmentation and are not easy to manage)
15. Secondary storage (magnetic recording)
16. I/O system (mainly understanding interrupt and interrupt shielding)
