3. Hardware

4. Every part sits on the mother board or connects to this
Memory slots
Main Power Connector
CPU Socket
IDE connector: for Hard drives, CD ROMs etc..
USB Port
Printer, mouse etc
PCI Slot
For video cards, modems etc..
Motherboard
Heart of computer
Every part sits on the mother board or connects to this

5. CPU CPU Central Processing Unit Brain of the computer
Runs the software and the data that you work on
Heat Sink
Cools CPU
CPU

6. Temporary Storage: RAM
Random Access Memory
Volatile or Temporary storage(Does not hold data when computer turned off)
Sits on motherboard
Holds the data and software that you are currently working with and running
When the computer is turned off the contents of RAM are lost
Often adding more RAM to your machine will speed up the computer

7. Graphics card
The CPU, working in conjunction with software applications, sends information about the image to the graphics card. The graphics card decides how to use the pixels on the screen to create the image. It then sends that information to the monitor through a cable.

8. *A graphics card's processor, called a graphics processing unit (GPU), is similar to a computer's CPU.
*Designed specifically for performing the complex mathematical and geometric calculations that are necessary for graphics rendering.
*produces a lot of heat, so it is usually located under a heat sink or a fan.
GPU uses special programming to help it analyze and use data.
*ATI and nVidia produce the vast majority of GPUs on the market,

9. NONVolatile or “more permanent” storage (holds data when computer turned off)
HDD and SSD
Magnetic HDD
Main storage for the computer
Cheaper than SDD
Made of thin platters
Retains data even when power is turned off
Solid State Drive (SSD)
Main storage for the computer
More expensive than HDD
*more durable than HDD
Retains data even when power is turned off

10. NONVolatile or “more permanent” storage (holds data when computer turned off)
External Hard Drive
Connects to Computer’s USB port
or can be wireless Does not sit inside the computer
Can be HDD technology or SSD
Used often to back up files

11. Inside the HDD Magnetic Hard Drive
Holds data even when power is turned off
sealed aluminum box, which has been opened in this photo.
When you turn the power of the computer on the information is loaded from the hard drive into RAM.
Usually known as your C : drive
This hard drive has three platters, also called hard disks, and six read/write heads.
