Accuracy refers to how close the observed value is to the true value. When each physical quantity is to be represented by a numerical value, a standard must be formulated and a unit must be selected.
In structural design, different accuracy should be set for different links, and higher accuracy should be set for sensitive links, so as to obtain higher overall working accuracy through more economical methods.

Matters needing attention
Power supply is a device that provides power for electronic equipment, also known as power supply, which provides all the components in the computer with the required electric energy. Whether the power, current and voltage of the power supply are stable will directly affect the working performance and service life of the computer.
The computer power supply is a closed independent component installed in the main chassis. Its function is to change the AC power supply into stable DC power supplies such as 5V, -5V,+12V,-12V, +3.3V through a switching power supply transformer, and supply power for system versions, floppy disks, hard disk drives, various adapters, expansion cards and other system components in the mainframe box.
Uninterruptible power supply (UPS) supported by HP, such as HP PowerTrust, can prevent instantaneous power failure, and the connection mode of disk and power supply circuit should be that mirror copies are connected to different power supplies respectively. The root disk and its corresponding nodes should be powered by the same power supply circuit.
