  • Hard Disk

The hard disk was found directly underneath the cd/dvd drive. It can hold up to 250.0 Gigabytes of data.

Inside the hard drive is the disk where memory is stored in and a spindle motor that reads and writes the information onto the disk.

  • Motherboard

The motherboard is the green board underneath and connected to all of the other components. The lines on the motherboard are electrical paths where data, instructions and power are moved between components.

  • Crystal

On the motherboard is a quartz crystal hidden underneath a metal cover. The crystal oscillates to produce ticks that indicate one cycle and executes one instruction.

  • Small Battery

There is a small battery on the motherboard that is responsible for keeping track of the date and time, so it is still running while the computer is turned off.
