Booting (power-on startup)
12/28/2014 3
Loading the system files of the operation system from the diskinto the computer memory.
Types of Booting:
1. Cold Booting: turn ‘’ ON’’ the computer by pressing onthe power switch ’ ’ON’’ in front of the Case.
2. Warm Booting: if the computer is already ‘ON’ and werestart it.
BIOS
12/28/2014 4
BIOS ( Basic Input Output System): It is type of Firmware thatstored in a ROM Chip (or BIOS Chip) on the motherboard containsinstructions and setup for how your system should boot (power-onstartup) and how it operates like; POST (Power-On Self Test ) andloading operating system etc.
Firmware: It is a permanentsoftware programmed intothe ROM.
Computer Casing
12/28/2014 5
It is a box (or enclosure) that contains the most of the computercomponents and connecting them with the peripherals devices.
What does it contain?
1. Power Supply2. Hard Disk Drive3. Diskette Drive4. CD/ DVD– ROM Drive5. Motherboard
12/28/2014 6
Switch Mode Power Supply: Supplying and regulating the powerthat needed to all computer components to perform the requiredprocess for the system to operate properly.
The Models of Power Supply (according to theMotherboard Form Factor):
1. AT (Advanced Technology).2. ATX (Advanced Technology eXtended).
1. Power Supply (or SMPS)
Uninterruptible Power Supply (UPS): It is a device that stores theelectricity and automatically supports the computer component bypower when the electricity failures in order to not damage thecomputer component and loss the data
UPS

1. Power Supply (or SMPS)
A Power Supply has three types of connectors used to power thevarious devices inside the Computer Casing:
1. Molex Connector: for (HDD and CD/ DVD- ROM).2. Berg Connector: for FDD (Floppy Disk Drive).3. System Connector: for the motherboard power supply.
The back of Power Supply contains of:1. Exhaust Fan Port.2. Monitor Power Connector.3. Computer Power Connector.

4. CD/DVD- ROM
CD/DVD- ROM: It is a device that is used to read CDs/ DVDs, Ifcapable of writing to the DVD, then it is often referred to as aCD/DVD- Burner or CD/DVD- RW.
Connected directly to the motherboard across data cable and to thepower supply a cross the power supply cable (Molex).
DVD- RW
5. Motherboard
12/28/2014 11
Motherboard: It is a printed circuit board (PCB) in form of physicalarrangement that holds the computer `s basic circuitry andcomponents. It is placed inside the computer Casing .
