How computers complete information processing tasks

Computers complete information processing tasks through a single instruction; computer instructions are instructions and commands that direct the work of the machine. A program is a series of instructions arranged in a certain order. The process of executing the program is the working process of the computer; information processing is It refers to the process of obtaining information and using certain methods and equipment to process the original information according to certain purposes and steps to transform it into usable and effective information.

What does the computer use to complete the information processing task

The computer completes the information processing task through a single instruction

Computer instructions are instructions and commands that direct the work of the machine. A program is a series of instructions arranged in a certain order, and the process of executing the program is the working process of the computer.

What is the process of processing information in a computer?

Extraction stage: The input device inputs the original data or information into the computer memory for storage.

Decoding stage: Interpret values ​​into instructions according to the instruction set architecture (ISA) definition of the CPU.

Execution stage: The controller then transfers the data that needs to be processed or calculated into the arithmetic unit.

Final stage: The output device outputs the final calculation result.

Expand knowledge

Information processing (Inforantion Processing) refers to obtaining original information, using certain methods and equipment, and according to certain purposes and The general term for the process of processing raw information and transforming it into usable and effective information. It can be seen that information processing includes the collection (acquisition), storage, processing, transmission and presentation of information.

• Acquisition of information

The Internet, which connects computers distributed around the world, has become the basis for the normal operation of modern society. If you want to obtain more information at a faster speed, browsing the Internet is an ideal method.

• Storage of information

The use of large-capacity computer storage devices to store data has a reliability and permanence that exceeds anything in history Information storage carrier.

• Information processing

Computers that can perform hundreds of billions or even trillions of operations per second provide people with fast Ability to process information accurately. It can analyze useful information at the fastest speed from the ever-changing and overwhelming information for people to make decisions.

• Transmission of information

Information transmission is the transmission of commands or status information from one end to the other end through the channel, and is received by the other end. Includes transmission and reception. There are two types of transmission media: wired and wireless. Wired is a telephone line or a special cable; wireless uses radio, microwave and satellite technologies. Information cannot be changed during information transmission, and the information itself cannot be transmitted or received. There must be a carrier, such as data, language, signal, etc., and there must be a common interpretation of the carrier on the transmitting and receiving sides.

• Representation of information

Multimedia computers organically combine various traditional information display means (such as text, images, sounds, etc.) Together, information can be presented to people in a more colorful form.

It is precisely because of the above reasons that the information industry has become the first industry in the world.
