Who knows what abbreviations are for English terms in computers? It is better to have Chinese notes

Computer Technology English Abbreviation SSL. Chinese name: computer technology.

Computer technology is introduced as follows:

Computer technology includes: basic principles of computing methods and combinator design, instruction system, CPU design, pipeline principle and its application in CPU design, storage system, bus and input and output. Computer technology has obvious comprehensive characteristics, and it is closely integrated with electronic source engineering, applied physics, mechanical engineering, modern communication technology and mathematics, and has developed rapidly.

The first general-purpose electronic computer, ENIAC, was based on radar pulse impulse technology, nuclear physics electronic counting technology, and communication technology at that time. The development of electronic technology, especially microelectronic technology, has had a major impact on computer technology, and the two have penetrated each other and are closely integrated. Achievements in applied physics have provided the conditions for the development of computer technology:

Superconducting technology, optical fiber technology, thermal and photosensitive technology, etc., are widely used in computers.

Mechanical engineering technology, especially precision machinery and its process and metrology technology, is the technical backbone of computer peripherals. With the progress of computer technology and communication technology, as well as the growing demand of society for the network of computers to achieve resource sharing, computer technology and communication technology have also been closely integrated, which will become a strong material and technological foundation of society.

1. Computer network: It is a system that uses communication equipment and lines to interconnect multiple computer systems with different geographical locations and independent functions, and realizes resource sharing and information transmission in the network with perfect network software.

2. Online system: It is a computer system composed of a computer connected to a large number of geographically dispersed terminals.

3. PDN: It is a public data network. The network transmits digitized data and belongs to a kind of communication subnet.

5. Data communication: It is a communication technology that completes the transmission, transfer, storage and processing of data encoded signals through computers or other data devices and communication lines.

6. Data transmission rate: the number of bits of binary information that can be transmitted per second, in b s

7. Channel capacity: It is the limit of the ability of information to transmit data, and the maximum data transmission rate of information.

8. Self-synchronization method: refers to the method by which the receiver can extract the synchronization signal from the data signal waveform.

9. PCM: Pulse code modulation is the most common method to convert analog data into digital signal coding.

10. FDM: also known as time-division multiplexing technology, is to divide the total bandwidth of physical shutdown into several sub-shutdowns with the same bandwidth as the transmission of a single signal under the condition that the channel bandwidth exceeds the bandwidth required by the original signal, and each sub-information transmits a signal.

11. Synchronous transmission: It is to use a batch of characters as the transmission unit, only add synchronization marks at the beginning and end, and synchronization between characters and bits is required.

12. Error control: refers to the technology and method that can find or correct errors in the process of data communication and limit the errors to the smallest allowable range.

13. Signal: It is the electronic or electromagnetic code of data.

14. modem: also known as modem. Its function is to complete the conversion between digital data and analog signals, so that the transmission of analog signals can transmit digital data.

The transmitter modem converts the digital data into an analog signal, and the receiver modem demodulates the analog signal to the original digital data.

15. Signal transmission rate: also known as the code element rate, modulation rate or baud rate, which indicates the number of code elements transmitted through the channel per unit time, and the unit is recorded as band.

17. Serial communication: The data is transmitted bit by bit on a communication line, which is slower than parallel communication and has a long transmission distance.

18. Hostage: A device or computer that receives and processes information in the process of communication.

19. Source: A device or computer that generates and transmits information in the process of communication.

20. Full duplex: allow data to be transmitted in two directions at the same time, there must be two data channels, and the sender and receiver must have independent receiving and sending capabilities.
