What does the red light of the computer host mean?
1. The red light on the computer host is generally a signal indicator light for the hard disk to read data;
2. The computer hard disk reads data and the indicator light flashes at the same time. , the more frequently it flashes, the more frequently the hard disk reads data;
3. The host flashes red light, usually due to the frequent exchange of data between the CPU, memory and hard disk. If the memory is too small or the CPU's ability to process data is weak, or the amount of data to be read from the hard disk is large, the red light will flash wildly.
Extended information:
The flashing red light indicates that the hard disk data is being read. This is normal during the boot process and will also occur when running a certain If a program is flashing, if it is a large program such as a running game, it will also flash for a long time or stay on. Don’t worry. As long as the power is not accidentally cut off while the red light is flashing, it will not cause any damage to the hard disk. This is normal. Scope of use.
The memory on the motherboard is usually called a memory stick (long green bar), which is a component for data storage and exchange in the computer. Because the CPU needs to exchange data with external memory (such as hard disk, floppy disk, optical disk) when working, but the speed of external memory is far lower than the speed of CPU.
So we need a device that works faster, in which the temporary storage and exchange of data can be completed. This is the main function of memory. The most common role of memory is to transfer data between the hard disk and the CPU.
