Anonymous users2024-02-05Microcomputer Principles is only for non-computer science majors, and most of them explain the structure of 8086 and how it works, as well as how to write assembly language. Principles of Computer Composition How the various parts of a computer are implemented (circuits). Computer architecture talks about how to design computers according to different scenarios and use cases 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 is about how to make the cache (DRAM four transistors form a unit), while the computer architecture is about how to use the cache in the CPU (multi-level cache, different levels of cache use different addressing methods) to achieve 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, we talk about how to do the hard disk and the physical mechanism of the head reading and writing, while the computer architecture talks about how to design the disk arrangement to meet the requirements of the probability of unexpected data loss at the lowest cost.

Anonymous users2024-02-03Take a computer and conduct research as it says, and you will never be able to learn computer technology just by reading books without using your hands.
The fundamentals of software technology are of the nature of an introductory course, which does not have a deep theoretical status, but it can open a door to the computer world for you.
This course is mainly divided into three parts, the first part talks about operating systems, mainly to let you understand how the various software of a computer works on a hardware platform. Learning this part well can effectively help you learn the subsequent course - microcomputer principles and also help you become a good software engineer - after all, a good software engineer must have a clear understanding of the dependencies between hardware platforms and software systems.
The second part deals with data structure and algorithm analysis. Therefore, this part is best learned after learning a little bit of C language, mainly talking about some commonly used data structures, and how to propose solutions to practical problems (this is what the algorithm means). Since this is an introduction, it will not be very in-depth, and a special course on "Data Structure and Algorithm Analysis" will be offered in subsequent studies.
The third part talks about software engineering, which is not interesting, that is, we have to talk about the outline, when we design large-scale software, we should control the development and testing process in a way of engineering management. Since there is no opportunity for everyone to practice for the time being, it is just a matter of listening.
This course is generally an introduction, and if you learn it well, it will be more interesting and easier to take the subsequent courses. But, after all, it's just an introduction, and if you really want to become a master, you can't rely on it.

Anonymous users2024-02-01Computer systems are divided into software systems and hardware systems. The software system is composed of system software and application software, which can be described as the soul of the computer. The hardware system is an integral part of the entire bare metal, which can be described as the body of the computer.

The frequency range of the energy concentration of the signal. As for the percentage of the range of signal energy concentration that is considered bandwidth, it depends on different actual needs. The criterion for judging is that the signal spectrum in a certain frequency range has basically provided the information we need, then the signal spectrum outside this frequency range becomes dispensable. >>>More
