These two books are enough
If you want to know more about it
I want to learn the basic knowledge of computers
I went to the bookstore to buy a book, and there was a CD attached. After reading the book, I quickly got started with the CD tutorial. I want to learn the basic knowledge of computers.
1. Understand the basic composition of computers
Generally, the computers we see are composed of three parts: the host (main part), the output device (monitor) and the input device (keyboard and mouse). The host is the main body of the computer. In the main chassis, there are: motherboard, CPU, memory, power supply, graphics card, sound card, network card, hard disk, floppy disk drive, CD-ROM drive and other hardware.
basically speaking, computers can be divided into five parts: arithmetic unit, memory, controller, input device and output device.
2. Understand the computer system
A computer system is divided into two parts: hardware and software. Hardware is equivalent to a person's body, while software is equivalent to a person's soul.
and hardware is generally divided into host and external devices. The host is the core component of a computer, which is usually placed in a chassis. External devices include input devices (such as keyboard and mouse) and output devices (such as monitors and printers).
software is generally divided into system software and application software.
3. What basic parts do you need to buy to assemble a computer?
(1) Chassis, where the main parts of a computer are usually placed.
(2) The monitor is used to see the working process of the computer, otherwise, you don't even know what the computer is doing.
(3), keyboard and mouse, input useful commands to the computer and let it work for us.
(4), the motherboard, this is a very important thing, although it looks a bit ugly, here is one of the important parts that determine the performance of your computer.
(5), memory, when the computer works, the computer will store the stored data here, which is equivalent to human memory.
(6) CPU, also known as central processing unit, is the core of computer operation and control.
(7) Graphics card, through which the computer transmits to the monitor.
(8), sound card, the computer sends sound to the speaker through this thing.
(9), hard disk, people often say that my hard disk is as large as G, which means the capacity of this hard disk, and the more G, the more things I can hold.
(1) Floppy drives, that is, things for inserting floppy disks, are generally 3.5-inch ones now, and 5.25-inch ones in ancient times. Now we go to buy them and people don't sell them.
(11), optical drive, of course, listening to CDs is indispensable. Sometimes some software you want to install is on CDs, so this is too useful.
(12) power supply, which is mainly used to convert 22V external power supply into various DC power supplies for various parts of the computer
4. How to evaluate the quality of a computer
Of course, the quality of a computer should be measured from many aspects, not just one or several performance indicators. Generally, there are several performance indicators to evaluate the quality of a computer.
(1) CPU type and clock frequency. This is the most important performance indicator of a computer, which determines the most basic performance of a computer. In the past, we often called 286, 386, 486, 586, 686, etc. according to the model of CPU.
The clock frequency is a measure of a computer working at a fixed beat, also known as the main frequency. The higher the clock frequency, the shorter the clock cycle, the shorter the time it takes to execute instructions and the faster the operation speed.
(2), the capacity of memory
The unit of memory is MB. Usually, people always refer to how much MB my memory has, such as 32MB, 64MB, 128MB, 256MB, etc. The larger the memory capacity of a computer, the more complicated the tasks that the computer can handle and the faster it will be.
(3) Configuration of external devices
High-end computers generally have soft and good monitors, keyboards, mice, speakers and so on.
(4) Running speed
The running speed of a computer is mainly determined by the speed of CPU and memory.
(5) Bus type
The more bus bits, the higher the machine performance.
(6) Compatibility
Whether there is a wide range of compatibility, including whether it can run all kinds of application software developed on computers and accept all kinds of expansion cards of computers. Who can provide me with some basic knowledge of programming
Look at the basics of computer culture
Then look at Tan Haoqiang's C Programming Language
After that, I want to learn c++ and c++ primer. I want to learn some basic knowledge of computers
If you want to learn these things, you don't have to spend that money at all. There are a lot of materials on the Internet. < p
the key depends on whether you are willing to study hard. I'll give you a website here. It's up to you whether you learn or not.

who can teach me some basic computer knowledge? I want to learn programming
# include <; stdio.h>

} I want to learn some basic computer knowledge.
After surfing the Internet for five or six years, I have mastered the basics. As for programming, it is not a basic thing. If I want to engage in computer software, programming is the foundation. If I want to solve computer problems, I can master the hardware almost. I don't attend computer training classes. You can buy your own books and read them. If you feel good, you'd better go to training.
What I want to say is that without the foundation of higher education, it is very difficult to learn programming. You should have a basic knowledge of English and logical thinking. If you want to learn, you should first learn C language, the basic language of its computer. Once this is understood, others can continue. I want to learn computer hacking. Who can tell me the simple basic knowledge? <
you have to hack some basic knowledge of the computer first, please
1kb = 124b, 1mb = 124kb, 1tb = 124gb, 1gb = 124m
B (byte) is the most basic unit of measurement in the computer, and b(bit, bit, pay attention to the difference between this B and uppercase B. 1B=8b. An English letter or number takes up one byte of space in a computer, and a Chinese character takes up two bytes (called a word), that is, 1 word =2 bytes.
The basic architecture of a computer mainly includes:
1. Motherboard-like ASUS, MSI, Gigabyte, etc., and the CPU architecture is different. Motherboards are divided into INTEL series and AMD series. He can integrate
2, CPU-- this is just like our brain, which is used for processing. The greater the frequency, the faster the cache processing will be. The Core Dual-core, E55,Q88 and I-series, which we often visit now, are produced by INTEL, and another CPU manufacturer is AMD. ADM58+, which we often visit, is this part
3. Memory is set up to speed up the access of hard disk and CPU. The more space it has, the faster the bus frequency will be. We learn KINGTONG, VATA, and so on. Generally, Kingston has better compatibility. Who can tell me some basic knowledge about universities?
This is good. Although you are only a freshman, it is necessary to know the university you have been striving for for for many years, so you should not study for the university entrance exam. You should have a long-term goal. What needs to be told in advance here is that going to college does not mean the end, but just a new beginning in life.
In fact, nowadays, the concept of university is no longer out of reach, and even many people look down on it. But I need to say that people who have attended university may regret it for four years, but those who have not attended university will regret it for life, so it is still necessary.
Today's university is no longer a symbol of ivory tower. University is a measure of the overall education level of a country's citizens, which is helpful to the nation and their future life, and can improve their personal cultivation and professional quality in an all-round way.
As for what they do when they go to university, in fact, there is a lot of space left for individuals in the university, and sometimes there is no course arrangement for one day. The purpose is not to let you play. Hehe, this arrangement is to let you live independently, arrange your own time reasonably, learn to be independent, and lay the foundation for leaving the campus. Outside of classes on campus, there will be more opportunities to participate in various social activities. Schools' associations, sports and people from different ethnic groups and countries have the same nature as undergraduate courses, and they all belong to the unified enrollment recognized by the state (different from the adult education self-taught examination of social youth). The main difference lies in the fact that the training goal of specialized courses is quality and skilled talents, and more of them tend to be professional and skilled talents, which is also strongly advocated by the state at present. The undergraduate course lasts for 4 years, which mainly trains high-quality talents who can continue their studies, and tends to theoretical and academic research. Because the society generally has a good impression on undergraduates, most people still hope to take an undergraduate course. But both junior college and undergraduate course belong to higher education. At the end of the undergraduate course, English will be specially tested, and a bachelor's degree can be awarded after passing the exam. There is no junior college. You can continue your studies, and you need to take another exam before you can further your studies.
At present, the major settings in each university are basically the same, such as Chengdu University of Traditional Chinese Medicine, whose specialty is in the direction of traditional Chinese medicine. University of Electronic Science and Technology of China, then his specialty is in computer-related fields, so when choosing a major, you need to fully think about your hobbies and your specialties, and then apply for the corresponding university. Therefore, major selection is also very important.
The difference between compulsory and elective is equivalent to that the courses in your chosen major direction must be tested every year. Elective means that you like other professional hobbies in your spare time, but it is not a compulsory subject. The public course in the university is an open-book exam, that is, you can look through books to find the answer.
There are many associations, including official ones such as the Student Union. Flying official organizations, such as basketball association, calligraphy association, badminton association, etc., is characterized by concentrating everyone's interests and hobbies, so you can join if you are interested, and generally there will be no membership fee.
The bachelor's degree is the lowest, followed by the master's degree, the doctor's degree and the postdoctoral degree. However, you don't have to learn that if you don't do scientific research or become a scientist.
Come on, young people should work harder, struggle harder, and go to dinner. Haha, I hope I can help you. It took me nearly 3 minutes to type it word by word for you. If you understand it in detail, please adopt it. If you have any questions, please ask or write privately. If you encounter a typo, it may be a mistake, which is purely accidental, hehe.
