  1. 1. Motherboard SORAN UNIVERSITY School of Engineering Department of Petroleum Engineering Prepared by: Rebaz Abdulqadr Hamad Aras Bahri Salim Dlvin Taher Abdullah Shno Husen Ali Zana Qadir Mahmud Dr. Muhammad Amin Aras Masud
  2. 2. purpose of a motherboard in a computer: The motherboard is the main printed circuit board and contains the buses, or electrical pathways, found in a computer.
  3. 3. Introduction to motherboard The motherboard (also known, system board, planar board) is the main circuit board inside the PC. It holds the processor, memory and expansion slots and connects directly or indirectly to every part of the PC.
  4. 4. What are the part in the motherboard: the parts of the motherboard includes : CPU Socket Heat sink Cooling fan CMOS Battery and many other more.........Some of the most important parts are the CPU, which you may have to buy separately
  5. 5. Motherboard components:- o ROM o CPU cooler o Heat Sink o Memory Socket o Cache and/or cache Sockets o CMOS battery o BIOS
  6. 6. Motherboard components:-  ROM(Read Only Memory):- Pronounced for read only memory, computer memory on which data has been prerecorded. Once data has been written onto a ROM chip, it cannot be removed and can only be read.
  7. 7. Motherboard components:-  CPU cooler The simplest type of cooler is a heat sink, which is a metal cover glued to the chip that provides a larger surface area for heat dissipation.
  8. 8. Motherboard components:- Heat Sink The simplest cooler is an aluminum heat sink, which uses fins to provide the maximum cooling surface for making contact with the air.
  9. 9. Motherboard components:-  Memory Socket:- A memory slot, memory socket, or RAM slot is what allows computer memory (RAM) to be inserted into the computer. Depending on the motherboard, there will usually be 2 to 4 memory slots
  10. 10. Motherboard components:- Cache and/or cache Sockets:-  Cache is a high-speed access area that can be either a reserved section of main memory or a storage device.
  11. 11. Motherboard components:-  CMOS battery: A battery that maintains the time, date, hard disk and other configuration settings in the CMOS memory. CMOS batteries are small and are attached directly to the motherboard.
  12. 12. Motherboard components:-  BIOS:- BIOS (Basic Input/ Output System), is also known as ROM BIOS, or System BIOS. It is a chip located on all motherboards that contain instructions and setup for how your system should boot and how it operates.
  13. 13. Motherboard components:- Four main functions of BIOS:-  POST  Bootstrap Loader  BIOS drivers  BIOS or CMOS Setup
  14. 14. How to replace the CMOS battery:  In many cases, the battery is soldered directly onto the motherboard, but the battery is usually in some sort of holder so it is easy to replace.  first try leaving the computer on for 24-hours. In some cases this can charge the battery and resolve your issue.  Most computers have a small battery. just after open the cover we see the battery in some sort of holder then put it out and put another on in it.
  15. 15. The Mother of All Motherboards old new
  16. 16. Motherboard form factors: As computers advanced, so have motherboards. Below is a listing of the various motherboard form factors and additional information about each of these form factors including ATX the most commonly used motherboard form factor today.  AT  ATX  Baby AT  micro ATX  Full AT  Full ATX  BTX  LPX  NLX  And More …….
  17. 17. Difference and Companies:  Differences between ATX motherboard and BTX motherboard:  The difference between an ATX motherboard and AT motherboard:  Motherboards companies: intel , asus , msi , , and more.
