Anatomy of a computer

2. Motherboards often have these integrated. If a motherboard does not have this or if you want better sound quality, you can buy it. Most of them attach to one of the mother board’s PCI slots.
4. Many peripherals, such as MP3 players, modern printers, and PDAs require this. some devices are able to draw power from the computer in addition to data through it.
7. you can use these to connect to different types of peripherals, including digital cameras and digital video cameras, they are also hot swappable.
8. Though some newer mice and keyboards include USB cables, most require this. Manufacturers mostly color these purple and green.
10. these slots let peripherals communicate quickly with the processor.
11. older printers and scanners connect the device to it. USB and FireWire connections are quickly replacing these on most peripherals, including scanners and printers.

1. large pcb that that houses most of a computer's components and also directs data traffic to and from the appropriate devices.
3. It acts as the brain of a computer. It is not visible when you open the case because it is covered by a heatsink which cool the processor.
5. is also known as a com, and is much slower than new USB and FireWire ports.
6. the motherboard manufacturer installs a basic OS in it. It activates when you turn on the computer and per-forms system check before starting the main OS, and also lets the processor communicate with the PC’s peripherals.
9. It houses the graphic card which supplies the image to the monitor. These generally produce better quality images compared to generic integrated chips.
11. it funnels power through each multicolored cable to each device.
12. Is where the CPU stores temporary data relating open programs. When it reaches its capacity, it redirects the excess data to the hard drive. Usually, you can improve the performance of a computer by adding another
