When the desktop computer is turned on, should the host computer or the monitor be turned on first?

When the desktop computer starts, turn on the monitor first, and then play the host computer.

1. Computers can be divided into external devices and internal devices. External devices refer to monitors, keyboards, mice, printers, speakers, etc. Internal devices are hosts and hardware in hosts.

2. Please turn on the external device before turning on the internal device. That is, turn on the display, printer, etc. First, then turn on the host.

3. Turn off the internal equipment first, and then turn off the external equipment, which is the reverse of the startup sequence.

4. The advantage of this is to avoid the influence of unstable voltage and current generated when external equipment is turned on and off on the electronic components and hard disk data of the host computer. Especially for early CRT monitors, the voltage and current will be relatively large when they are turned on and off.

With the progress of hardware technology, these problems have less and less influence on the host, but good habits still play an important role in computer maintenance.
