The conceptual differences between computers and computer

Computer "The concept of the largest, including large machines, medium-sized machines, minicomputer and other microcomputers. and "microcomputer" is the abbreviation of "microcomputer". "Computer" is a metaphor for microcomputers. So, conceptually speaking, "computer" and "microcomputer" should be equivalent. The most common is the microcomputers that people call "computers". Some medium-sized machines, small machines (such as ibmas400,ibmrs/6000) can only be seen in research institutes or large websites and commercial organizations.

Computer:

The computer is the tool that completes the information processing, the modern computer is a kind of digital electronic equipment that can complete the information processing quickly and efficiently.

Computer:

The computer has the super memory ability, the high speed processing ability, the very high computational accuracy and the reliable judgment ability. Any complex mental work that people do, if it can be broken down into the basic operations that a computer can perform, and expressed in a form that the computer can recognize, is stored in the computer. Computer can imitate a part of people's thinking activities, instead of part of human mental work, according to People's will automatically, so someone also called the computer "computer."

Computers have many similarities in function with the human brain. For example, the brain's memory function, computational function, judgment function. Computer is not the human brain, it can not completely replace the human brain, but it is not correct to say that the computer can not simulate the function of the human brain, although the computer in many ways than the human brain, but it also has a lot of performance beyond the human brain, the brain and computer in many ways complementary. Basic knowledge of the computer

PC Machine:

PC is the abbreviation of personal Computer. That's the usual personal computer. PCs are divided into ibm-pc and Apple machines. IBM-PC is an electronic computer developed by IBM that targets small and individual users. Apple's Apple PC is a ibm-pc competitor. Due to the widespread popularity of IBM-PC, IBM-PC has become a representative of the PC, also become the standard of the PC. The PC is now commonly referred to as the IBM-PC Standard PC. The Apple PC is referred to as an apple machine.

One interesting phenomenon in real life is that students in science and engineering often refer to microcomputers as "microcomputers" or "computers", while liberal arts students and home users are more likely to call microcomputers "Computers".

Server:

Server is a high-performance computer, as a network node, storage, processing network 80% of data, information, so also known as the soul of the network. To make an image of the analogy: the server is like a post office switch, and computers, notebooks, PDAs, mobile phones, such as fixed or mobile network terminals, such as scattered in the home, a variety of office space, public places, such as telephones. Our daily life with the outside world, the work of telephone exchanges, communication, must pass through the switch to reach the target phone; Similarly, network terminal equipment such as home, the computer in the enterprise Internet access, access to information, communication with the outside world, entertainment and so on, must also go through the server, so it can be said that the server in the "organization" and "leadership" These devices. Getting Started with computers

Single Board Machine:

Single Board machine is a PCB circuit board on the CPU, a certain capacity of the rom,ram and I/O interface circuits, such as integrated circuit films assembled together into the microcomputer, and equipped with simple peripherals such as keyboards and monitors, usually in the PCB curing with a ROM or eprom small size * program. Basic knowledge of computer questions and answers

Single-chip computer:

It's just a computer, it's just *, though small, spite: It also uses modules similar to computer functions, such as CPU, memory, parallel bus, and the same storage device as the hard disk, except that the performance of these components is much weaker than that of our home computer, but the price is low, Generally not more than 10 yuan can ... Using it to do some control of electrical appliances a class of not very complicated work is enough. We now use the automatic drum washer, fume hood VCD and so on inside the home appliances can see its figure!...... It is mainly used as the core component of the control part
