PCs ENVIRONMENT and PERIPHERALS Lecture 2

System units: Mother board. Computer Fan Computer CasePower supply

Computer Case: - Cover the mother board content. - Give your pc a nice look. It is so important for safety:- - Protect your PC from any outside thing(Dust, liquid….) Case style: - Tower, Desktop case. - The common type of the case : AT, ATX. - Not cost money and stay long time even you upgrade your PC.(unless manufactory change the basic style.)

Power supply : - Power supply: Main article. - Supply power to computer. - Usually with a cooling fan to make PC cold. - There are many power cables from power supply to mother board and devices (Hard disk, Floppy, CD-Drive…)

Computer Fan: - Used to lower the temperature of the computer.

Motherboard: - The mother board is the key components of your computer. - It serve as the main computational and processing source of your PC. - It is the body or main frame of the computer which all other components interface. - Provides connections to all other components that must attach to it.

Motherboard(continue) - The motherboard contains sensitive components : electronic components. - Memory, chips, cards, CPU and any devices you see a circuit board in it’s body and you should use it careful. - Quality of PC depend on quality of electronic components.

Motherboard:

The Motherboard components: What are two main components on the motherboard?  Central Processing Unit (CPU) :Also called a processor Electronic device that interprets and carries out the basic instructions that operate the computer  Memory Temporary holding place for data and instructions

The Motherboard components: 1- IDE socket (Integrated Drive Electronics ).(for HD, CD) 2- FDD Socket (Floppy Disk Drive). 3- socket for power supply (to mother board). 4- port for Mouse, Keyboard. 5- port for Printer. 6- MEMORY. 7- CPU Processor socket. 8- Bios and cmos. 9- CHIPSE (for control). 9- EXPANSION SLOTS.(other cards) 10- Other CHIPSET for control. 11- Other Sockets

The Motherboard components: IDE socket FDD Socket MEMORY SLOT EXPANSION.(other cards) port for Mouse, Keyboard.Printer. power supply socket Processor socket Bios and cmos Other CHIPSET

The Motherboard components:

IDE socket ( Integrated Drive Electronics ). - For HD drive and CD drive. - IDE socket : 40 pins. - Nowadays IDE socket is founded in the old PC editions, SATA socket is more common. IDE socket Data cable

IDE socket ( Integrated Drive Electronics ).

(FDD Socket (Floppy Disk Drive - For Floppy Drive pins.

Storage Devices: - Hard Disk Drive. - Floppy Disk Drive. - CD Drive.

Hard Disk Drive: There is two types of hard drive connectors the computer could use to transfer data : PATA, SATA. PATA : parallel Advance Technology Attachment. SATA: Serial Advance Technology Attachment.

Hard Disk Drive:

Connect by : Data Cable(to IDE socket) – power cable(to power supply)

Hard Disk Drive:

Floppy Disk Drive. Connect by : Data Cable(to FDD socket) – power cable(to power supply).

Floppy Disk Drive:

CD Drive: Connect by : Data Cable(to IDE socket) – power cable(to power supply).

CD Drive:

IDE socket (HD – CD):

Processor (CPU): Type of CPU by the way that connect with motherboard: 1- socket CPU. 2- slot (old CPU).

Processor (CPU):

1. Unlock the socket by lifting the lever up to 90 degree angle 2. Position the CPU so that the CPU corner with the golden triangle matches the socket corner with the small triangle. 3. Carefully insert the CPU into the socket until it fits in place. Processor (CPU installation ):

4. When the CPU is in place, push down the socket lever (until it clicks on the side tab) in order to secure the CPU. Now the lever in locked state Processor (CPU installation ):

Mention the advantages of SATA over PATA and the disadvantage of SATA ? Which one is the best ?
