The basic hardware configuration of the computer is as follows:
1. Motherboard: Installed with the main circuit system that makes up the computer, generally including BIOS chip, I/O control chip, keys and panel control switches Components such as interfaces, indicator light connectors, expansion slots, DC power supply connectors for motherboards and plug-in cards. The type and grade of the motherboard determine the type and grade of the entire computer system, and its performance affects the performance of the entire computer system.
2. CPU: Also known as central processing unit, it is an integrated circuit module that mainly interprets computer instructions and processes data in computer software. The function of an instruction is often implemented by components in the computer performing a series of operations. The CPU must generate corresponding operation control signals based on the function of the instruction and send them to the corresponding components, thereby controlling these components to act according to the requirements of the instruction. .
3. Memory stick: The memory stick is used to temporarily store data. It is also installed on the motherboard and is a computer component that the CPU can address through the bus and perform read and write operations. Any kind of input and any kind of output on the computer can only be performed through memory. The performance indicators of the memory stick depend on the storage capacity, access speed (storage cycle), and memory reliability.
4. Hard disk: It stores all the user’s data information, which affects the running speed of the computer and the user’s operating experience. As the data storage of the computer system, the capacity is the main parameter of the hard disk. The speed of rotation determines the internal transmission rate of the hard disk. The rotation speed is expressed in revolutions per minute (RPM). The larger the RPM value, the faster the internal transmission rate, the shorter the access time, and the better the overall performance of the hard disk.
5. Monitor: It is an I/O device of the computer, that is, input and output devices. Usually, an alignment film is installed on two glass substrates, and the liquid crystal will be aligned along the grooves. Under the action of different currents and electric fields, the liquid crystal molecules will be regularly rotated 90 degrees and arranged, resulting in a difference in light transmittance. In this way, when the power is turned on and off The difference between light and dark is produced under the action, and by controlling each pixel according to this principle, the desired image can be formed.
