All parts of the computer are visible when first opening it.


2.8GHZ, 2058A453

The processor is on the motherboard.

Brand: Intel Model Number: Pentium 4

The central processing unit (CPU) is the portion of a computer system that carries out the instructions of a computer program, to perform the basic arithmetical, logical, and input/output operations of the system. The CPU plays a role somewhat analogous to the brain in the computer. http://en.wikipedia.org/wiki/Central_processing_unit



The RAM is sitting perpendicular on the motherboard.

Random access memory (RAM) is a form of computer data storage. Today, it takes the form of integrated circuits that allow stored data to be accessed in any order with a worst case performance of constant time. http://en.wikipedia.org/wiki/RAM

CD/DVD Drive

The CD/DVD Drive is on the opposite side as the motherboard in the corner.

In computing, an optical disc drive (ODD) is a disk drive that uses laser light or electromagnetic waves near the light spectrum as part of the process of reading or writing data to or from optical discs. Some drives can only read from discs, but recent drives are commonly both readers and recorders, also called burners or writers. http://en.wikipedia.org/wiki/CD/DVD_drive

Power Supply

210 Watts

The Power Supply sits in the corner next to the motherboard.

A power supply unit (PSU) converts mains AC to low-voltage regulated DC power for the internal components of the computer. Modern personal computers universally use a switched-mode power supply. Some power supplies have a manual selector for input voltage, while others automatically adapt to the supply voltage. http://en.wikipedia.org/wiki/Computer_power_supply

Hard Disk


The Hard disk is on the opposite side as the motherboard across from the Power Supply.

A hard disk drive (HDD; also hard drive, hard disk, or disk drive) is a device for storing and retrieving digital information, primarily computer data. It consists of one or more rigid (hence "hard") rapidly rotating discs (often referred to as platters), coated with magnetic material and with magnetic heads arranged to write data to the surfaces and read it from them. http://en.wikipedia.org/wiki/Hard_disk_drive


The Motherboard is next to the Power Supply.

In personal computers, a motherboard is the central printed circuit board (PCB) in many modern computers and holds many of the crucial components of the system, providing connectors for other peripherals. The motherboard is sometimes alternatively known as the mainboard, system board, or, on Apple computers, the logic board. http://en.wikipedia.org/wiki/Motherboard

  • Battery

The Battery is located on the Motherboard.

The memory and real-time clock are generally powered by a CR2032 lithium coin cell. These cells last two to ten years, depending on the type of motherboard, ambient temperature and the length of time that the system is powered off, while other common cell types can last significantly longer or shorter periods, such as the CR2016 which will generally last about 40% as long. http://en.wikipedia.org/wiki/Nonvolatile_BIOS_memory#CMOS_battery

  • Crystal

The Crystals are located on the Motherboard.

A crystal oscillator is an electronic oscillator circuit that uses the mechanical resonance of a vibrating crystal of piezoelectric material to create an electrical signal with a very precise frequency. This frequency is commonly used to keep track of time (as in quartz wristwatches), to provide a stable clock signal for digital integrated circuits, and to stabilize frequencies for radio transmitters and receivers. The most common type of piezoelectric resonator used is the quartz crystal, so oscillator circuits designed around them became known as "crystal oscillators." http://en.wikipedia.org/wiki/Crystal_oscillator#Electrical_oscillators
