One: The composition of the computer
When it comes to computer hosts, we usually refer to the computer's central processing unit (CPU), memory, motherboard, power supply, hard disk, graphics card, sound card, network card and other core components as a whole. These components work together to enable the computer to perform a variety of tasks, including browsing the web, working on documents, playing games, editing videos, and more.
The following are the main functions of each component:
- CPU (Central Processing Unit): The core component in the computer, mainly composed of three parts: arithmetic unit, controller and register. It is responsible for issuing the information required by each instruction of the CPU, and saving some temporary files of operations or instructions, which can ensure a higher speed. Equivalent to the human brain.
- Motherboard: Installed in the case, it is one of the most basic and important components of an electronic computer. The motherboard is generally a rectangular circuit board, on which are installed the main circuit systems that make up the computer. Generally, there are BIOS chips, I/O control chips, keyboard and panel control switch interfaces, indicator light connectors, expansion slots, motherboards and cards. DC power supply connectors and other components. Another feature of the motherboard is the open structure. Most of the motherboards have 6-8 expansion slots for plugging in the control card (adapter) of the peripheral equipment of the PC.
- Memory: The memory is the bridge between the CPU and the hard disk, and its size also directly affects the data exchange speed between the CPU and the memory. It is an important part of the computer. By using memory, the computer has a memory function. It stores the programs and data currently in use. Once the power is turned off, all the information it stores will be lost.
- Hard disk: It is a device for storing data such as data and software. It has the characteristics of large capacity and no loss of data when power is off. Also known as "data warehouse".
- Graphics card: As one of the processing centers for the output signal of the monitor, the graphics card can convert the output signal of the monitor into a digital signal that the computer can recognize and process.
- Sound card: As one of the interfaces for communication between the external equipment of the computer and the internal hardware of the computer, the sound card can convert analog audio signals into digital signals and process audio through digital signals.

Two: maintenance measures
Here are some computer maintenance measures:
1. Regularly clean the dust and dirt inside and outside the computer to ensure good heat dissipation.
2. Regularly back up important data to prevent data loss.
3. Install antivirus software and a firewall to protect your computer from viruses and malware.
4. Regularly update operating systems and applications to ensure they have the latest security patches and features.
5. Avoid installing unauthorized software on your computer or opening email attachments from untrustworthy sources.
6. Avoid using unsecured network connections on your computer, such as public Wi-Fi.
Three: help memory
Computer maintenance measures, small things that cannot be ignored.
Clean the inside and outside regularly for smoother heat dissipation and higher efficiency.
Back up important data to avoid data loss and make work easier.
Install anti-virus software and a firewall to protect the computer from virus attacks and make the system more secure and stable.
Update your operating system and applications to stay up-to-date and increase productivity.
Avoid installing unauthorized software and opening suspicious email attachments to ensure computer security.
Use a secure network connection, such as public Wi-Fi, to avoid information leakage and make your computer more reliable
