What is Post in computer term?
When a computer is booted, the basic input/output system (BIOS) performs a hardware check on the main components of the computer. This check is called a power-on self-test (POST).
For instance, Figure displays a screen capture of a sample POST being performed. Notice how the computer checks whether the computer hardware is operating correctly.
If a device is malfunctioning, an error or a beep code alerts the technician of the problem. If there is a hardware problem, a blank screen might appear at bootup, and the computer will emit a series of beeps.
BIOS manufacturers use different codes to indicate hardware problems. Figure shows a chart of common beep codes. However, motherboard manufacturers may use different beep codes. Always consult the motherboard documentation to get the beep codes for your computer.
