Soft exam Review

I have been reading some basic knowledge over the past few days.,For the Operating System,Process,Storage,Job Management,File Management.

For software engineering,This part is relatively simple,Because there is a basis for learning in the past, it is a review.

The same is true for databases. Most of the major content is a review. It is unfamiliar with relational algebra and tuples, and does not understand what they actually use.

Multimedia technology is just a general review. I know the principle of audio, video, and image is still unclear.

Now I see the principle and system of composition, pipeline, and high-speed cache. I know what they do, but I'm curious about how they actually implement it in real hardware.

I have been reviewing the soft exam for a while, and I feel that it is all theoretical support. I am not sure about the relationship with the actual application. I feel that there is still a great distance between the two. I don't know how to make up for this gap. Try to watch the video before the end of the Tomb-sweeping Day. Come on.
