CPU Reset, The BIOS there is a program called Power-On-Self-Test

CPU reset is performed the first PC. This is because the CPU is the most important component.

Then the first CPU reset to start all activities. CPU reset button is usually triggered by power, but can also be done from the network or other system.

Once the CPU is active then the Basic Input Output System (BIOS) will be active as well. BIOS works to serve the movement of data around each computer because this is where the system input and output information is determined. BIOS can be protected using a password to be able to start working.

So without the correct password the computer BIOS will not work. In the BIOS there is a program called Power-On-Self-Test (POST).
POST, BIOS, CPU Reset
Will conduct testing of the basic components of a computer. When the CPU reset to enable BIOS, POST program on the run. Was first examined by POST is the POST program integrity and the CPU reset  itself.

Moreover, the POST program checks the disk drives, monitors, RAM, and a keyboard. At the POST BIOS is active and has not been completed, you can interrupt the boot process and CMOS configuration.

CMOS is a small memory to store the BIOS configuration and its importance as a boot media, setting the processor, memory, and more.

Here also saved time and calendar accurate to a computer. CMOS battery is equipped with a special order in which data is not lost.

Disk boot

while the boot disk is needed after the POST is complete because the computer is ready to run the operating system is very useful to connect people with computers.

Run the operating system required an initial initialization system that will combine all functions into one computer and ready for use. Initial system is then stored in a computer readable media.

This media is called the boot disk. To continue the use of computers, disk boot media must absolutely nothing. Media regulation which would be the boot disk you can do in the BIOS. Once CPU reset or everything is complete, you are ready to use the computer.
