The booting software, known as BIOS (Basic Input Output System) give instructions to the POST (Power On Self-Test) which then runs tests to on the computer to make sure that all the devices are well connected to the computer. Sometimes this process is so fast that when observed, it appears as if there is are no tests being run by the POST process.
POST stands for power on self test it does basic hardware checks on the computer
POST means "Power On Self Test", and is a series of tests the computer will conduct before loading your operating system (i.e. Windows). Most desktop computers that pass POST will sound a single short beep.

Do you remember times when the computer performs the POST process you can see the process rate running on the computer's monitor? If you remember that make a note that today many hardware manufacturers bring in their logo when the computer is running the POST process. But you got many third party utilities to work with that.
