Question
Obtain a motherboard .
Using a drawing application of your choice, sheets of paper, or a digital camera, compose an image of the motherboard. You may not use an image made by another individual such as one on the Internet.
Identify the motherboard manufacturer and model number. You may use this information to find online documentation to assist you in the following steps. Indicate the full links to the online resources you used.
Resource(s): _____________________________________________________________
Indicate whether this motherboard is an ATX, BTX, ITX, or something else. Also explain how you were able to determine this.
On your motherboard image, label each of the following components. These are the minimum components that you need to identify. Include your labeled drawing immediately following this step (if you did a hand-drawing, you must scan it in and include it herein.)
CPU socket – also indicate socket type and number (examples: LGA 1155, PGA AM3+
Expansion slots – identify each type (PCI, PCIe, X1, PCIe X16, or other)
Memory slots – identify by type (DDR, DDR2, DDR3, DDR4, or other) and indicate how you were able to tell. Try to be as specific as possible
Chipset (in many cases there will be two chips, identify them as Northbridge (Memory Controller Hub) and Southbridge (IO Controller Hub or Fusion Controller Hub). In other cases there may only be one (such as with Platform Control Hub)
BIOS chip (on many newer boards this may be difficult to locate. Consult with your instructor and don’t stress too much over this one.
CMOS battery or battery holder. Note that this is not the CMOS itself!
I/O Ports (such as USB, video (if integrated), sound, Ethernet, etc.). Be specific on the I/O port names rather than collectively referring to them as the I/O ports.
Configuration jumpers (if any). Especially look for a CMOS reset jumper (or switch).
Storage device headers or slots (SATA, IDE, M.2, etc.)
Clock(s) – crystal oscillators (metal cans).
Power supply connector(s). On most motherboards you will find either a 20 or 24 pin main power connector and also a 4 pin (2x2) or 8 pin (4X2) ATX-12V connector . Refer to http://www.smpspowersupply.com/connectors-pinouts.html
USB Headers (for attachment of front panel USB ports)
Front Panel Header (for attachment of power switch and indicator lights).
Example front panel header:

Explanation / Answer
* Describe the differences between a PGA and an LGA CPU socket and the CPUs that would be used in each of these.
The PGA which is also called as Pin Grid. The Pin Grid array are having the pins on the CPU.
The LGA which is also called as Land Grid. The Land Grid array are having the pins on the motherboard.
we can also differentiate them by chip company like PGA is AMD and LGA is Intel.
The PGA has pins and the socket supports the insertion of the pins.
* Using a CPU socket chart (obtainable on the Internet), identify at least two CPUs that could be installed on this board. Be specific as to the manufacturer and model numbers of the CPUs.
The Intel Pentium and The pentium M are the two CPUS that could be intalled on the board.
The MMX and AMD also are the components could be intalled on the board.
* Explain how to easily differentiate between different RAM modules and their sockets (such as how to differentiate DDR2 and DDR3) when no labels are present.
There are two types in RAM that is DDR2 and DDR3.
So the DDR2 and DDR3 has the differences between the physically and performance wise.
The DDR2 and DDR3 are both 240 pin.
We can also identify the differenc by looking at the notch position of the slot.
The DDR2 and DDR3 have different notch positions.
* Consider the memory slots on your motherboard. Are the slots (or the retaining tabs) all the same color? What would be the significance of two (or more) different colored slots be?
The slots are different colors because one of the slots is for RAM and the other for the PCI expansion slots
* Explain why older motherboards had two chips (Northbridge & Southbridge) in the chipset while newer ones typically have only a single chip chipset.
In latest PCs and computers there will be an utilization of the chipset which will performs the duties of both the northbridge and southbridge.
* What changes in technology occurred that drove motherboard manufacturers to stop using socketed BIOS chips?
- The changes like testing the Controller chips on the Motherboard
- The changes like testing and Initialize I/O Interfaces.
- The changes like identify any media drives connected
- The changes like Initialize the BIOS Data Area in Memory
- The changes like Testing for indications of an OS Loader on any media
* Explain why removing the CMOS battery may not clear the CMOS contents on newer motherboards.
why because the CMOS battery does not store any data.
