“What is motherboard?” in general it is a very simple question but understanding a motherboard is very important to all guys who is working on a computer system. So here in this article you will get the answer of “What is motherboard? its Definition, major Component of motherboard & Types of a motherboard…
“What is motherboard?” Motherboard definition:
Motherboard, in simple words, is a PCB (printed circuit board) which is capable for expansion. We can fix other Modules and component over it. It is called motherboard because it acts as a source at which different devices can be connected. It is not only acts as a connecting source but also holds and allows communication between components like CPU and memory. There are a number of devices or peripherals which can be connected to the motherboard (devices like mouse, keyboard, scanner etc and other interface cards like sound card, video card, network card, TV tuner card and many more. Motherboard is also called main board, system board, base board, planar board, or logic board.
Whenever we hear about motherboard we think it is used in computer but sometimes this term is also used for single board devices which don’t have capability of expansion such as in printers, TV, washing machines etc.
Main Component of a motherboard:
Motherboard has a lot of components. These components are used to install other devices. Major components are described below:
Since mother boards differ from normal board due to expansion capability so these slots are most important. They are also of many types:
ISA or Industry Standard Architecture slot is very old slot. Initially it was used in AT boards and cards which were mandatory like we have sound and display card were put in this slot. It supports a 16 bit bus. Nowadays it is used very less.
PCI or Peripheral Component Interconnect slot is frequently used nowadays. Add on cards which we use to increase the functionality of our system are put in this slots . It supports 64 bit bus .
PCI express slots
They are the latest slots and they support full duplex serial bus. They are used for putting add on cards.
AGP or Accelerated Graphics Port slot is used only for graphics card. It supports 32 bit bus.
Since motherboard also facilitate communication between CPU and memory . so memory slots are important component of motherboard . They are mainly of two types:
SIMM stands for Single Inline Memory Module . it supports 32 bit bus. It was used in olden times. Nowadays you will not find this slot in motherboards.
DIMM stands for Double Inline Memory Module . It is used nowadays and supports 64 bit bus
Processors are installed using CPU socket . some of them are listed below.
- Socket 7- a 321 pin socket.
- Socket370- a 370 pin socket.
- Socket775-a 775 pin socket.
- Socket1156- a 1156 pin socket.
- Socket1366- a 1356 pin socket.
Socket7 and 370 were used in older motherboards. Socket775, 1156 and 1356 are the latest ones they also supports a number of new processors.
It stands for Basic Input Output System. It is used in motherboard in form of chip and used to perform hardware initialization during booting process.
It stands for Complementary Metal Oxide Semi conductor . It is a lithium cell which provide power supply to motherboard.
They are used to distribute power among all the devices connected to mother board. They are mainly of two types :
- AT connector- used in older motherboards.
- ATX connector- used in latest motherboards.
It stands for Integrated Drive Electronics . these connectors are used to connect hard disk and floppy disk
It stands for Serial Advance Technology Attachment. They are latest ones found in new motherboards and are faster than IDE connectors.
It is responsible for all calculations done.
Types of motherboard
There are a number of motherboards available. Some of them are listed below.
Stands for Advanced Technology . It was used in mid 80s . It is not very small and due to its size it can’t fit in mini desktops and laptops. It uses six pin plugs and now it is not used.
Stands for Advanced Technology Extended. It is the updated version of AT motherboard . The best thing about this motherboard is you can interchange its ports. They are also smaller in size then compared to AT motherboards.
Stands for Low Profile Extension motherboard . they were the first motherboards in which input and output ports were at back of the system because of this feature they became quite popular . but apart from that there were a number of reasons like absence of real AGP slot which led to its extinction.
Stands for Balanced Technology Extended. As the technology updated there was a need of such motherboards which could handle more power and release less heat , for that BTX was made. It was known for thermal and structural design.
Pico BTX motherboards
It is the smaller version of BTX motherboard . But it support only one or two expansion slots .
Mini ITX motherboards
Iit was made in 2001 . the best thing about this is it can be cooled very easily as it has excellent thermal design . It is generally used in PC systems.
Motherboard is a very big topic. It can’t be completely covered in one article . there are many things which we couldn’t cover like there classification , making etc . so we are hoping to cover them in our upcoming articles.
