Inside The Box


The motherboard is a printed circuit board that is the foundation of a computer, located at the bottom of the computer case. It allocates power to the CPU,RAM, and all other computer hardware components. Most importantly, the motherboard allows hardware components to communicate with one another..


The central processing unit (CPU), also called a processor, is located inside the computer case on the motherboard. It is sometimes called the brain of the computer, and its job is to carry out commands. Whenever you press a key, click the mouse, or start an application, you're sending instructions to the CPU.


The P4 connector is a 12V power supply cable like that shown in the picture used with motherboards that have an Intel Pentium 4 processor. The P4 cable has two black wires that serve as a ground and two yellow wires that are +12VDC.

Hard drive

The hard drive on your computer is where the software is installed, and it's also where your documents and other files are stored. The hard drive is long-term storage, which means the data is still saved even if you turn the computer off or unplug it.

When you run a program or open a file, the computer copies some of the data from the hard drive onto the RAM. When you save a file, the data is copied back to the hard drive. The faster the hard drive is, the faster your computer can start up and load programs.
