High scores: Explanation of computer terminology terms

Computer, commonly known as computer, is a modern electronic computer machine used for high-speed calculation, which can perform numerical calculations, logical calculations, and also has the function of storage and memory. It is a modern intelligent electronic device that can operate according to the program and process massive amounts of data automatically and at high speed.

A computer that consists of a hardware system and a software system without any software installed is called bare metal. It can be divided into five categories: supercomputers, industrial control computers, network computers, personal computers, and embedded computers, and the more advanced computers include biological computers, photonic computers, quantum computers, etc.

Development history: The evolution of computing tools has gone through different stages from simple to complex, from low to high, such as from knots in "knotted rope notes" to abacus, abacus slide rule, mechanical computer, etc. They have played their respective historical roles in different historical periods, and at the same time, they have also inspired the development of modern electronic computers.

In 1889, the American scientist Herman Holley developed an electric tabulator based on electricity to store calculations.

In 1930, American scientist Van Neva Bush built the world's first analog electronic computer.

**: A virtual site of a unit or individual on the Internet, which generally consists of a homepage and many web pages.

1. CISC: Complex instruction system computer, complex instructions, poor execution efficiency, slow data processing speed.

2. Memory bandwidth: the amount of information accessed by the memory per unit time is an important technical indicator to measure the data transmission rate. It is usually measured in bit-seconds or byte-seconds.

3. Data paths: the channels for transmitting information between many registers, oaks and memories.

4. Instruction resource correlation refers to the conflict between multiple instructions entering the pipeline and competing for the same functional component in the same machine clock cycle.

5. Destination state: the state of the CPU when executing the destination program.

6. Serial computers: refers to a series of computers with the same basic instruction system and the same basic architecture.

7. Random memory: refers to the content of the storage unit in the sock memory can be accessed randomly, and the time and the physical bit of the storage unit.

Irrelevant. 9. Instruction resource related: refers to the competition for the same functional component in the same machine clock cycle after multiple instructions enter the pipeline.

Conflicts that arise.

Interrupt the service entry point of the source device, which is called a vector interrupt.

11. Instruction system: The collection of all machine instructions in a computer is an important factor in characterizing the performance of the computer.

is a command for a computer to perform a certain action.

12. Random memory: the contents of the memory unit in the memory can be accessed randomly, and the time type and the physical location of the memory unit.

Independent. 13. The PPU (peripheral processing machine) PPU works independently of the host and has its own instruction system, completes arithmetic logic operations, reads and writes the main memory, and exchanges information with peripherals.

14. The state of the management program of the operating system running on the management of the CPU.

15. The channel channel is a special function processor, which can realize the unified management of peripheral devices and the memory of peripheral devices.

Data Transfers.

16. CISC: Complex instruction system computer, complex instructions, poor execution efficiency, and slow data processing speed.

17. Memory bandwidth: the amount of information accessed by the memory per unit time is an important technical indicator to measure the data transmission rate.

It is usually measured in bit-seconds or byte-seconds.

18. Data path: the path through which information is transmitted between many registers and memories.

19. Instruction resource related: refers to the competition for the same functional component in the same machine clock cycle after multiple instructions enter the pipeline.

Conflicts that arise.

20. Destination state: the state of the CPU when executing the destination program.
