1. Explorer Inside the Computer
Ms. Dareen Rabah

2. Objective What does the inside of a computer look like?
How did the computer become known as the stored-program computer?
Have a look at computer part

3. Table of content Tower CPU Motherboard Memory Power supply
Expansion card
Fan
Reviewing question

4. Tower A computer tower, also known as a computer case.
Include the motherboard, hard drive, power supply, optical drives and as well as other parts.

5. CPU The brain of computer is CPU or central
process unit. Its control information and
tell other parts what to do, like:
Converts data into information
Control center
Set of electronic circuitry that executes stored program instructions CU
ALU

6. CU Control Unit (CU) It is Part of the hardware that is in-charge.
Directs the computer system to execute stored program instructions.
Communicates with other parts of the hardware.

7. ALU - + / * > = NOT OR >= < > AND
Performs arithmetic operation like:
Addition
Subtraction
Multiplication
Division
Performs logical operations
Evaluates conditions
Makes comparisons
Can compare
Numbers
Letters
Special characters - + / *
> =
NOT OR
>=
< >
AND

8. Motherboard
The motherboard is like a big city with many streets and highways that connect all of the buildings together. Instead of streets and highways, the motherboard uses tiny electrical paths to connect each component of the computer together. These paths are called "buses." The more buses that connect to a component, the faster it can operate. Larger buses are able to operate faster than smaller buses.

9. Memory
memory module has several memory chips. The computer uses this memory constantly to temporarily store information, (or data), while it is working with it. If a computer has a lot of memory, it can store more temporary information and operate faster.
Main type of memory

10. Main type of memory
ROM
RAM
Disk Drive

11. ROM Read Only Memory (ROM)
Data and instructions can be read, but not modified
Instructions are typically recorded at factory

12. RAM Data and instructions can be read and modified
Random Access Memory (read and write memory)
Data and instructions can be read and modified
RAM chips will remember what you tell them. But, when the computer is turned off, RAM forgets everything you told it. This is why we need to save our work on computer.

13. Disk Drive
Disk Drive read information off of storage disks. the most common disk drives are:
CD-ROM
Hard Drive

14. CD- Drive To install software onto the computer. Backing up data
copying/listening to music files and MP3s.

15. Hard Drive
This stores large amounts of data for a computer that stay while the computer is turned off.

16. What type of memory is volatile
1. Cache 2. Hard drive 3. RAM 4. ROM

19. Power supply
The power supply supplies the electrical power for a computer. It supplies power to the motherboard, drives, and certain expansion cards.

20. Expansion card
On the motherboard, you will find several expansion cards:
Sound card
Video card
Modem card

21. Sound Card
The sound card contains special circuits for operating the computers sound.
The sound card is what processes a computer's sound data.

22. Video Card
The video card handles graphics that are displayed on the monitor.

23. Modem Card
Modems change a computer's digital information into analog waves that can travel through the phone lines to another computer. The other computer's modem then changes the analog waves back into digital information, so that the
other computer can
understand it.

24. Which part of the computer does an EIDE cable connect to?
1. Floppy drive 2. Hard disk drive
3. Sound card 4. Video card
