Types of Motherboard components and their functions

Motherboard Components-this time the admin wants to share info about the motherboard components, because the components found in the strongly motherboard vary between:
A. Motherboar Chipset.

The motherboard Chipset determines the compatibility (suitability) of the motherboard with some other system components that are very vital. It will also determine the performance and limitations of the mot

herboard. The Chipset will consist of a micro circuit group contained in several integrated chips or one or two integrated Very Large Scale Integration (VLSI) chips. VLSI is a chip that has more than 20.000 circuits. Th

e Chipset will determine the following things:

  • Amount of RAM that can be used by the motherboard
  • RAM Chip Type
  • Cache size and speed
  • Processor type and speed
  • Expansion slot type that the motherboard can accommodate.


The Read-only Memory (ROM) Chip is located inside the motherboa

rd. The ROM Chip contains instructions that can be accessed directly by the microprocessor. Unlike RAM, ROM chips take back what they contained in spite of the computer being turned off. R

OM contents cannot be deleted or changed in normal way. Data Transfer from ROMS is slower than RAM, but faster than any disk. Some examples

of ROM chips can be found in the motherboard including the BIOS ROM, electrically erasable programmable read-only memory (EEPROM), and Flash ROM.

The Basic Input/Output System (BIOS) has instructions and data in the ROM chip that controls the boot process and computer hardware. BIOS is sometimes also called firmware. ROM chips that contain firmware are called the BIOS ROM chip, ROM BIOS, or simplified to BIOS. Usu

ally the BIOS location in the motherboard is marked. This BIOS system is a very important part of the computer. If the CPU is said to be a computer brain, the system BIOS is the heart of the syste

m. The BIOS will determine what hard drive the user has installed, where there is or not the 3.5 inch floppy drive, what kind of memory is installed and many other important parts of the system hardware at startup time. Th

e BIOS is responsible for serving the relationship between computer operating software and various hardware components that support it. Some of the following responsibilities include:

  • Hosting Program setup for hardware
  • Test the system in a process called POST
  • Control all aspects of the boot process
  • Extracting audio and video error codes when there is a problem during POST
  • Provides basic instructions for computers to manage devices in the system
  • Find and execute any BIOS code in the expansion card
  • Find the boot volume or sector of any drive to start the operating system
  • Ensure compatibility between hardware and system.

BIOS is easily visible because it is bigger than most other chips. It often has a glossy plastic label that contains the name Manufakturer, serial number chip, and chip production date. This information is very important when it comes time to choose the chip for the upgrade process.

ROMS are the most commonly used way to store system-level programs that must be available in a PC at any time. The most common example is the system BIOS program. The BIOS Program is stored in a ROM named system BIO

S ROM. Having this program in a permanently saved ROM means providing data when power is turned on. Therefore, the PC will be able to use it to boot up the system.

EPROM and EEPROM are ROM chips that can be uninstalled and reprogrammed. Erasable Programmable read-only memory (EPROM) is a special type of programmable read-only memory (PROM) that can be removed using ultraviolet rays passed through the invisibility window above the chip. Becau

se the ROM chip has instructions that can make the device work properly, it should sometimes be reprogrammed or replaced when the instruction for the upgraded device is needed. Unlike EPROM, EEPROM chips can be removed using a normal power voltage higher than using an ultra violet beam. When the B

IOS system is loaded in EEPROM, it can be upgraded by running certain instructions.

Flash ROM is a special EEPROM chip that can be developed as a result of EEPROM development technolo

gy. Toshiba creates terms for the ability of the chip can be removed in seconds or very quickly. Flash ROM Set the BIOS on most new systems. This Flash ROM can be reprogrammed under the use of special software co

ntrols. Upgrade the BIOS by using a special software known as flashing. BIOS is implemented in flash memory known as plug-and-play BIOS, and it supports plug-and-play tools. The Chip retr

ieves data when the computer is turned off so that information is permanently stored. Flash memory is cheaper and more powerful than the EEPROM chip technology

D. Expansion slots

Expansion Slot is an outlet in the computer's motherboard that receives printed circuit boards. Expansion slots are also known as socket names. All computers have an expansion slot that creates additional devices to be connected to the co

mputer. The device includes a video card, an I/O card, and a sound card. Here is an example of expansion Slot image.

E.  Riser Cards

The riser Card (booster) is used when the computer is fully loaded. Physically will add a slot so that the chip or card can be plug. In a simple view, the case is more cost-efficient, the card is pinned into a riser card that is located parallel to the motherboard.

Audio/Riser Modem (AMR) is a plug-in card for Intel motherboards. AMR contains audio and or modem circuits. Intel Specification 46-pin connector edge to provide digital interface between card and motherboard.

 AMR has all the analog functions, or code, required for audio and or modem operation. AMR evolved into a kartuC

ommunications and Networking Riser (CNR), which adds functionality to LAN and home networking.

CNR Card, CNR is a 30-pin interface that accommodates two formats and makes audio/modem variation and audio/network possible. Mobile Daughter Card (MDC) equivalently with AMR for laptop computers.
