Types Of Motherboard

Types Of Motherboard

There are diffrent types of motherboard and thery are:-

1. XT-  E xtended Technology
2. ATX- Advanced Technology
3. Baby At- BabyAdvanced Technology
4. ATX- Advanced Technology Extended
5. BTX- BalanceTechnology Extended

 XT- X tended Technology

Xt stands for Extended technology. This is old types of motherboard means old model of motherboard which is not not used nowadays. In this mother we can found old types of processor socket LIF (Low Insertion Force) sockets, ram slots DIMMs( Dual inline Memory Module) and ISA (Industry Standards Architecture) slots, 12pin Power Connector and no any external  ports.
They have slot type processors, DIMMs memory modules, ISA slots for add-on card, and no ports. There are connectors and add-on cards for ports.
Eg: Pentium-I, Pentium -MMX, Pentium -II and Pentium-II Processors.

 AT Motherboards:

AT stands for Advanced Technology.
In Advanced Technology of Motherboards we can see PGA (Pin Grid Array) Socket, SD Ram slots, 20pin power connector from SMPS ( switch mode power supply) to motherboard, PCI slots and ISA slots.
we find the above components which is found in  AT motherboards.

Eg: Pentium-III Processors

 Baby AT Motherboards:

Baby AT Motherboards is the combination of both XT and AT.
This is little bit changes each other because it has got both slot type processor sockets and PGA processor sockets, while, AT motherboard  have PGA socket And XTotherboard have Slot types of processer socket, SD Ram slots and DDR Ram slots can be found in this motherboard, PCI slots and ISA slots, 12 Pin power connector and 20Pin power connector and Ports.

Eg: Pentium-III and Pentium-IV

ATX Motherboard

ATX motherboards stands for Advanced Technology eXtended which  have a central Northbridge chip encircled by the CPU, RAM, drive, and power connections; expansion slots; and connections for
external devices.ATX motherboards use mini-DIN (PS/2) connectors for the keyboard and mouse, and most have integrated USB ports. Many also feature onboard modem and NIC ports, FireWire ports, sound, and video. ATX motherboards dominate the PC market. Two popular variations of the ATX form factor are microATX and FlexATX. These use the same power connections and have the same basic layout as ATX but are scaled to fit in to much smaller ATX cases. Full-sized ATX motherboards will not fit into microATX or FlexATX cases, although most full sized cases support the smaller motherboards.

The power supply connector from the smps to motherboard is 20pin or 24 pin.

BTX Motherboard

BTX stands for Balance technology Extended. Fast CPUs and powerful graphics cards in today’s PCs create. phenomenal amounts of heat, which motivated the PC industry to create the “coolest” form factor used today -the Balanced Technology eXtended (BTX) form factor. BTX defines three subtypes: standard BTX, microBTX, and picoBTX, designed to replace ATX, microATX, and FlexATX,
respectively. At first glance, BTX looks like ATX, but notice that the I/O ports and the expansion slots have switched sides. Everything in the BTX standard is designed to improve cooling. BTX cases vent in cool air from the front and vent out warm air in the back. CPUs are moved to the front of the motherboard so they benefit from the cool air entering the front of the case. BTX defines a special heat sink and fan assembly called the thermal unit. The thermal unit’s fan blows the hot CPU air directly out the back of the case, as opposed to the ATX method of just blowing the air into the case and letting the power supply and case fans pull air out. The BTX standard offers better cooling than ATX, but the PC industry tends to take its time when making big changes like moving to a new form factor. As a result, BTX has not yet made much of an impact in the industry, and BTX motherboards, cases, and thermal units are still fairly rare.
