When people have computers they think its cool, and amazing to have one. So over time they get used to using the computer and think they know everything to do with the computer, because there so used to it, but they do not know the works of the inside of a working computer. When your PC is turned on, most of the electricity starts to warm up the components that will be used on in a few seconds to send, receive, slice, hash, squeeze, and memorize bits and bytes of data flowing through the system like a busy station. The path takes the current to the CPU or microprocessor, main and head of the whole system. In this case, it’s the first instruction, and the address is located on a flash memory chip on the computer’s motherboard. All together, they’re called the BIOS because they work as the computer’s basic input and output system. The first trickle of electricity has done its job. Now the BIOS takes over the task of awakening the computer’s components, giving them a pop quiz called the power-on self-test to make sure the needed parts of the computer are there and functioning properly. The BIOS starts off by checking a small, 64-byte chunk of RAM located on a complementary metal oxide semiconductor chip that is kept alive by a battery even when the computer is off. The BIOS has the CPU send signals over the system bus to be sure all the basic components are functioning. The BIOs checks to see if its used in a cold boat, which is when the computer had been turned off, or it is a warm boat or a reboot. The POST sends signals over specific paths on the bus to the internal floppy, optical, and hard disk drives, and listens for a response to determine which drives are available.

This picture is a motherboard with all parts that helps bring all our computers that we use daily in the world today together. The Mother board is the uniting element among all the chips and circuitry that make up a computer. Devices connect with each other through the motherboards circuits which give them their power. In the following paragraphs i am going to name common parts of the motherboard:
Memory slots are current slots support DDR and DDR2 RAM, which is now the more popular type of memory.
Power Supply Connections are older boards have only one 20-pin connector.
IDE Connector are connects to two EIDE/ATA hard drives and optical drives using the older parallel connection.
CPU Socket determines what kind of raicroprocessor, or CPU the motherboard uses.
The North Bridge and South Bridge together form the computer’s chip set, secondary only to the processor in determining the performance and capabilities of a PC.
South Bridge is two-digit display that provides codes used in troublshooting a disable PC.
Battery keeps the BIOS chip drive.
Floppy Disk Connections only communicated with a floppy drive, that works your floppy disk.
Ports is an input or output panel that holds the miscellaneous ports on the back and front of the PC that are used for communicating with external devices.
Expansion Slots are additional capabilities that can be added to the computer by plugging a circuit board called an expansion card in one of the slots.
USB is the slots in which you can connect keyboards, mouses, and your USB drive ( holds files and documents)
