Why is a computer a representative of electronics?

Well, in addition to computers, there are many electronic products, such as flashlights, watches, mobile phones, and televisions, all of which belong to electronic products, but he is the best and most direct two, but it is also a machine.

Because many industries are based on computers, imagine that without computers, how can there be any industrialization now? Therefore, the computer represents a sign of electronic products.

The development of electronic products is largely due to the emergence of computers, and the computer itself is an electronic product, so it can be said that the computer is a representative of electronic products.

A computer is a general term, which is a device that stores all intelligent data operations. So he is one of the most representative products in electronic products.

Because the computer can drive the development of the industry, it is a symbol of electronic products, which is understandable.

Because computers are powerful, they can do many things well, and they are the first electronic products to be developed.

Now the highest technology of electronic products is embodied in the computer, so the computer is a representative of it.

Because electronic products are inseparable from computers, we say that computers are a representative of electronic products.

People commonly refer to computers as PCs, abbreviated for personalcomputer, abbreviation, personal computer. In 1986, IBM developed the first PC, which is called like an electronic brain, so it is also called a computer. People refer to the computers that are compatible with IBM-PCs as IBM-compatible computers.

According to the performance index, PC is a kind of microcomputer, and microcomputer is referred to as microcomputer. Computers are divided into giant machines, such as Deep Blue, which won chess with Garry Karparovska, Galaxy II, etc. There are also mainframes, mediums, minicomputers, and microcomputers.

When we usually say computer, we mean electronic digital computer.

The work of an electronic computer is based on the principle of an electronic pulse circuit, which consists of electronic circuits that constitute its various functional components, in which the propagation of electric fields plays a major role. We know that electromagnetic fields travel very fast, and today's high-performance computers can perform tens of billions of additions per second.

If a person can do an operation in one second, then the average computer has to do more than 100 years of work in one hour. In many cases, the speed of the operation plays a decisive role. For example, computer-controlled navigation requires "computing speed faster than an airplane can fly."

Meteorological forecasting requires the analysis of a large amount of data, such as 10 days and a half months for manual calculation, which loses the significance of forecasting. With a computer, you can calculate a weather forecast for several days in an area in a few minutes.

Electron tubes, transistors, large-scale integrated circuits, large-scale integrated circuits, ultra-large-scale integrated circuits, due to the development of integration technology, the integration of semiconductor chips is higher, each chip can accommodate tens of thousands or even millions of transistors, and combinators and controllers can be concentrated on a chip, so that microprocessors appear, and can be assembled into microcomputers with microprocessors and large-scale, ultra-large-scale integrated circuits, which is what we often call microcomputers or PCs.

The microcomputer is small, cheap, and easy to use, but its power and computing speed have reached or even surpassed the mainframe computers of the past. On the other hand, various logic chips made by large-scale, ultra-large-scale integrated circuits have been made into supercomputers that are not very large in size, but can be operated at a speed of 100 million or even billions of times.

In 1993, China succeeded in developing a galaxy-type general-purpose parallel supercomputer that operates 1 billion times per second, following the successful development of the galaxy-type supercomputer that operates 100 million times per second in 1983. This period also saw the emergence of a new generation of programming languages, as well as database management systems and lead-nano network software.

With the change of physical components and devices, not only the computer host has undergone upgrading, but also its external equipment is constantly changing. For example, the external memory has developed from the original cathode ray display tube to the magnetic core and magnetic drum, and then developed into a general-purpose disk, and now there is a smaller, larger, and faster read-only optical disc (CD-ROM).

Computers are electronic products.

Electronic products are related products based on electrical energy, mainly including: watches, smart phones, televisions, DVD players (VCD, SVCD, ***), video recorders, camcorders, radios, cassette recorders, combination speakers, laser record players (CDs), computers, game consoles, mobile communication products, etc. Because the early products were mainly based on electron tubes, they were called electronic products.

Electrical appliances refer to devices that complete specific functions through power transmission, such as televisions, washing machines, refrigerators and other household power callers. Electronic products, on the other hand, refer to products that use electronic components to complete specific functions, such as mobile phones, tablets, digital cameras, etc.

As a comprehensive product, the computer not only includes the electrical part of electrical engineering (such as power supply, circuit board, electrical components, etc.), but also includes the sub-part of power distribution in electronic engineering (such as CPU, memory, hard disk, etc.). Therefore, computers belong to both electrical appliances and electronic products.

Computers are both electrical appliances and electronic products. Technically, a computer is an electronic device composed of many electronic components that can process and store information. As a result, computers are classified as electronics.

But from the point of view of use, the computer is also a clean household appliance like Yiqinghu, which can provide office, entertainment and other functions to meet people's living needs.

The household appliances are divided into two major categories: mechanical and electronic products, such as refrigerators, washing machines, etc., which should be mechanical, while TV consoles, computers, etc. are all electronic products, and electronic cracking products belong to household appliances.

Semiconductor electrical components. Limited to the size of the computer and **, the capacity of the memory receptacle is generally not very large, but required.

Access time. Short. It is impossible to store the contents of the memory memory for a long time, and it is only necessary to provide temporary programs and data for calculation. There is also an auxiliary storage in addition to the computer, also called.

External memory. Abbreviated as external memory. External memory is used to replenish memory and store programs, data and calculation results for a long time. The contents stored in the external memory cannot be used directly by the computer, but must be fed into memory and then provided to the computer from the memory.

External memory is characterized by large capacity, the ability to store stored content for a long time, and the speed of access.

Slower than memory. External memory is usually used with disks and.

Tape. The disk is made up of.

Why is an electronic computer called a computer? Why is the standard name for a computer an electronic computer?

The four stages of development of computers:

The first stage of development: 1946-1956 in the era of tube computers. In 1946, the first electronic computer was introduced at the University of Pennsylvania in the United States, and it was designed by von Neumann.

It covers an area of 170 square meters, 150kw. The computing speed is slow, and no one is fast yet. It is a milestone in the history of computer development.

ENIAC (Electronic Numerical Integator and Calculator) stands for "Electronic Numerical Integator and Calculator".

The second stage of development: the computer age of transistors in 1956-1964: the operating system.

The third stage of development: the computer age of integrated circuits and large-scale integrated circuits from 1964 to 1970.

1964-1965) (1965-1970) Fourth stage of development: 1970-present: the computer age of VLSI circuits.
