In this issue, Xiaobian will bring you the main performance indicators of computer hardware systems. The article is rich in content and analyzed and described from a professional perspective. After reading this article, I hope you can gain something.

The main performance indicators of computer hardware systems are: CPU, which determines the performance of notebook computers; word length, which is the number of binary data bits that the CPU can directly process; computing speed, which refers to the number of instructions that the computer can execute per second; capacity, which measures the performance of a memory; frequency, which refers to the clock frequency of the computer.

The main performance indicators are as follows:

1、CPU

CPU is the most important factor in determining the performance of notebook computers. Computer computing speed refers to the number of instructions that the computer can execute per second, that is, the average number of times the CPU "runs" per unit time.

2. Word length

Word length is the number of binary data bits that CPU can directly process, which is directly related to the calculation accuracy, function and speed of the computer. The longer the word length, the stronger the processing power. Common microcomputer word lengths are 8 bits, 16 bits and 32 bits.

3. Calculation speed

Computing speed refers to the number of instructions that a computer can execute per second, usually in MIPS.

4. Capacity

One of the factors that measures a memory's performance is its capacity, which is usually 2GB or 4GB as standard on laptops today.

5. Main frequency

Frequency refers to the clock frequency of the computer, expressed in MHz.

extended information

A computer system consists of hardware and software. Hardware composition: input device, output device, memory, arithmetic unit, controller; software composition: program and related documentation collectively.

The hardware system is mainly composed of CPU, memory, input and output control system and various external devices. Software is divided into system software, support software and application software.

Computer systems are characterized by accurate, fast calculations and judgments, and good versatility, easy to use, and can be connected to networks.

Calculation: Almost all complex calculations can be realized by computers through arithmetic operations and logical operations.

Judgment: The computer has the ability to distinguish different situations and select different treatments, so it can be used in management, control, confrontation, decision-making, reasoning and other fields.

Storage: Computers can store huge amounts of information.

Accuracy: As long as the word length is sufficient, the calculation accuracy is theoretically unlimited.

Fast: The time required for a computer operation is as small as nanoseconds.

General purpose: The computer is programmable, and different programs can achieve different applications.

7, easy to use: rich high-performance software and intelligent man-machine interface, greatly convenient to use.

Networking: Multiple computer systems can transcend geographical boundaries and share remote information and software resources through communication networks.

The above is what are the main performance indicators of the computer hardware system shared by Xiaobian. If there is a similar doubt, please refer to the above analysis for understanding. If you want to know more about it, please pay attention to the industry information channel.
