7- Proprietary Case

Question number 8

What is Power Supply?

A power supply convert 110, 220 or 240 Volt AC into DC Voltages, That's a computer needs to operate.

These Voltages are

+5VDC, -5VDC, +12VDC, -12VDC, +3.3VDC, +5VDC Stand by power.

Question number 9

How many power connector use by power supply?

There are 4 types of power connectors use by the power supply.

1- Floppy Drive Power Connector (Berg)

2- AT System Connector

3- ATX Power Connector

4- Standard Peripheral Power Connector (Molex)

Question number 10

What is Floppy Drive Power Connector?

There are four pin power connector or four wire going to this connector +5VDC Carried on the Red Wire and +12VDC Carried on the Yellow Wire and two black ground wires.

It is also know as Berg Connector.

Question number 11

What is ATX power connector?

ATX stands for (Advanced Technology Extended) it is type of motherboard power connector it is provide the power of ATX newly and latest type of motherboard.

It has 20 pins and carry.

+5VDC, -5VDC, +12VDC, -12VDC, +3.3VDC, & +5VDV Stand by Power.

Question number 12

What is AT power connector?

AT stand for (Advanced Technology) it was oldest motherboard Technology. Now a days it is not in use so basically it had 2 Six pin separate power connector. And it was carry 4 voltages these voltages are.

+5VDC, -5VDC, +12VDC, -12VD

QUESTION NUMBER 13

What is standard peripheral power connector?

There are four pin connector basically used to provide the power of internal disk storage devices such as hard disk drive, compact disc and DVD.

It has 4 pin and carry same two voltages as floppy drive power connector they both are same according to power but according to size or shape they are not same sometime standard peripheral power connector larger and flatter than floppy drive power conductor.

Question number 14

What is Motherboard?

Respire of the computer system is the motherboard. it is made up of green and brown fiberglass and it is placed in bottom or side of the case it is very important component of the computer system because it connect all the components to each other sometime it is also known as planner Board of system board.

Question number 15

How many types of motherboard

According to main classification there are two types of motherboard

1. Integrated motherboard

2. Non integrated motherboard

Question number 16

What is integrated motherboard?

In this type of motherboard the all components basically audio video and network devices such as audio port video port and network port is already  attach with the motherboard as a form of integrated circuit.

Question number 17

What is non integrated motherboard?

In the non integrated motherboard all these components means audio video and network devices is not integrated with the motherboard circuit non integrated motherboard required audio video and network devices to be added to the system with the expansion slot.

Question Number 18

What is ATX Motherboard?

ATX stand for Advanced Technology Extended it is very simple to identify because it has 20 pin single power connector found on the motherboard circuit to receive the power of the motherboard and also previously I have discussed ATX Motherboard always provide six voltages.
