- The Motherboard is visible when you first open the computer. The motherboard has everything on it, the processor, the crystal, the RAM memory, the power supply and most of the cables.
- Intel Pentium 4
- The processor contains many gates that are working very fast and it is the hottest part of the computer. According to Wikipedia a processor is, "is the hardware within a computer system which carries out the instructions of a computer program by performing the basic arithmetical, logical, and input/output operations of the system. The term has been in use in the computer industry at least since the early 1960s. The form, design, and implementation of CPUs have changed over the course of their history, but their fundamental operation remains much the same."

- Nanya and MT
- 572 MB
- RAM stands for Random Access Memory. The RAM memory is the programs of the computer while the computer is running. According to Wikipedia, the RAM is a random-access device allows stored data to be accessed in very nearly the same amount of time for any storage location, so data can be accessed quickly in any random order.

The CD/DVD Drive
- This computer has a CD drive. This drive takes compact disks and copies and plays the music from or onto your computer. You can save the files to your computer as well, so the songs are always on your computer.
- 210 Watts
- The power Supply powers the computer. According to Wikipedia "The desktop computer power supply changes alternating current from a wall socket to low-voltage direct current to operate the processor and peripheral devices. Several direct-current voltages are required, and they must be regulated with some accuracy to provide stable operation of the computer. A power supply rail or voltage rail refers to a single voltage provided by a power supply unit (PSU). Although the term is generally used in electronic engineering, many people, especially computer enthusiasts, encounter it in the context of personal computer power supplies."

- 80 Gigabytes
- According to Wikipedia "A typical hard disk drive has two electric motors; a disk motor that spins the disks and an actuator (motor) that positions the read/write head assembly across the spinning disks. The disk motor has an external rotor attached to the disks; the stator windings are fixed in place. Opposite the actuator at the end of the head support arm is the read-write head; thin printed-circuit cables connect the read-write heads to amplifier electronics mounted at the pivot of the actuator. The head support arm is very light, but also stiff; in modern drives, acceleration at the head reaches 550 g."

- The crystal makes the processor work very fast and helps regulate the processor. It works up to three billion actions per second. If a human made one action every second, for them to make three billion actions, it would take 95 years, as compared to the crystal making three billion actions every second. That's crazy!
- There is a small battery on the motherboard. This battery works when the computer is turned off. This battery keeps track of the time and day of the year even when the computer is off.
