4. XT

Answer 2

Answer:

These are some of the motherboards created by today:-

• AT motherboard- was produced in the mid eighties, Used till the time intel rolled out its Pentium 2 processor.
• ATX motherboard- stands for advanced technology extended, it was produced in the nineties as a replacement to the original AT motherboards.This type of motherboards differ from their AT counterparts in the way that these motherboards allow the interchangeability of the connected parts.These motherboards are also smaller compared to AT motherboards.
• LPX motherboard- stands for low profile extension.The major difference between these and previous boards is that the input and output ports in these boards are present at the back of the system. This concept proved to be beneficial and was also adopted by the AT boards in their newer versions. The use of a riser card was also made for the placement of some more slots. But these riser cards also posed a problem that the air flow was not proper.There were many unfavorable conditions which led to its extinction.
• BTX Motherboard:- BTX stands for Balanced Technology extended. BTX was developed to reduce or avoid some of the issues that came up while using latest technologies. Newer technologies often demand more power and they also release more heat when implemented on motherboards in accordance with the circa-1996 ATX specification. The ATX standard and the BTX standard, both were proposed by Intel. The further development of BTX retail products was canceled in September 2006 by Intel after the acceptance of Intel’s decision to focus again on low-power CPUs after suffering issues such as scaling and thermal with the Pentium 4.
• Pico BTX Motherboard:- Pico BTX is a motherboard form factor that is meant to manufacture even smaller size BTX standard. This is smaller than many current “micro” sized motherboards, hence the name “Pico” has been used. These motherboards share a common top half with the other sizes in the BTX line, but they support only one or two expansion slots, designed for half-height or riser-card applications.
• Mini ITX Motherboard:- Mini-ITX is a 17 × 17 cm (6.7 × 6.7 in) low-power motherboard form factor. It was designed by VIA Technologies in year 2001. These are largely used in small form factor (SFF) computer systems. Mini-ITX boards can also be cooled easily because of their low power consumption architecture. Such an architecture makes them widely useful for home theater PC systems or systems where fan noise can diminish the quality or worth of cinema experience. The four mounting holes in a Mini-ITX board line up with the four holes in ATX specification motherboards, and the locations of the back plate and expansion slot are the same. Although, one of the holes used was optional in earlier versions of the ATX. Hence, Mini-ITX boards can be used in places which are designed for ATX, micro-ATX and other ATX variants if required.
