• • • • • A hard disk drive is a data storage device used for storing and retrieving digital information using rapidly rotating discs coated with magnetic material. An HDD retains data and information even when powered off. They come in many shapes and sizes. A typical hard drive is about 6 inches long, 4 inches wide There will be two cables running out of the hard drive, one will probably have four colored wires this is power. The other will either be a ribbon-style cable, or sometimes in newer systems, there is a cable a little less than half an inch wide. Stores data. • The sound card is built inside the motherboard. • A sound card is an internal computer expansion card. • The sound card can input and output audio signals from and to the motherboard. • The colours on the a typical sound board are: • Blue (for line in) • Red (mic in) • Green (line out) • There are many colours… • • • • A video card has many different names. Most refer it to the Video card but others call it different names. Video cards come in 2 sizes. This allows laptops owners to add video cards if they want to. They are located around the back of you monitor. Also on the sides of laptops. They allow a picture to display on your television screen if you were to pug your laptop video card wire into the T.V. • • • • • It supply's power to a electrical device which requires a power supply. It controls the input voltage to a certain device. Say your device only needed 3V the power supply would regulate this at a constant. The location of the power supply differs in computers but they are mostly found at the back of the computer to allow the hot computer parts to cool down. The cooling fan cools the parts and lets the computer be used for longer times as the parts don’t over heat and melt. • • • • A CD-ROM is a pre-pressed compact disc. It can hold information like videos, images and games. The CD reader reads these disc and coverts the information onto your desktop screen. Certain CD ROM’s read certain, for example: The Xbox CD reader only reads Xbox games. Also a DVD CD reader can only read CD or DVD’s but cannot covert the game information from Xbox games or PS3 games. Location is at the front of computer • The CPU carries can input/output information given by the computer. • It is the brains of the computer as it sorts out information given by input signals. • Its also outputs information, like the images projected on the monitor. • It's located on the motherboard inside the computer tower (or inside the laptop). • The CPU is located under the heat sink that nearly always has a fan on top of it. • • • • • • The motherboard is the main circuit board of your computer. It holds many of the crucial components of the system. Attached to the motherboard, you'll find the CPU, ROM, memory RAM expansion slots, PCI slots, and USB ports. Basically, the motherboard is what makes everything in your computer work together. Each motherboard has a collection of chips and controllers. It contains most of the main components of the computer. • • • • • • Basic Input/Output System (BIOS) It contains instructions and setup for how your system should boot and how it operates. The BIOS contains all the code required to control the keyboard, display screen, disk drives and a number of miscellaneous functions. The BIOS is typically placed in a ROM chip that comes with the computer. Having a flash memory BIOS is good because this means it can be updated when needed. THE BIOS is located on the motherboard. • RAM stands for Random Access Memory. • It is temporary storage for data. • RAM is faster then ROM. • Disadvantage of RAM is that if the power supply is cut off then the data is then lost if it has not been saved beforehand. • RAM can be inputted into the laptop/computer or is built into the computer.
