This article compares the IBM compatible Personal computer Motherboard form factors – that is the different sizes and specific or de-facto standards of major system In the area of IBM compatible Personal computers the AT form factor referred to the dimensions and layout ( form factor) of the Motherboard for In the area of IBM compatible Personal computers the AT form factor referred to the dimensions and layout ( form factor) of the Motherboard for Enhancements Low-profile - With the push for ever-smaller systems a redesigned backplane that shaves inches off height requirements is a benefit to The ATX (for Advanced Technology Extended) form factor was created by Intel in 1995. LPX (Low Profile eXtension originally developed by Western Digital was a loosely defined Motherboard format ( Form factor) widely used in the 1990s NLX (New Low Profile Extended was a form factor proposed by Intel and developed jointly with IBM, DEC, and other vendors for low profile low cost mass-marketed microATX, also known as µATX (sometimes Transliterated as mATX or uATX on Online forums is a Small form factor standard The DTX Form factor was announced to be in development by AMD on January 10, 2007. FlexATX is a PC motherboard Form factor derived from ATX. The specification was released in 1999 by Intel as an addendum to the MicroATX The DTX Form factor was announced to be in development by AMD on January 10, 2007.

Mobile-ITX is the smallest x86 compliant motherboard form factor. Mini-ITX is a 17 x 17 cm (or 693 x 693 Inches) low-power Motherboard Form factor developed by VIA Technologies. Embedded Platform for Industrial Computing (EPIC is a computer Form factor standard put forth by a combined effort from WinSystems VersaLogic Octagon Systems Micro/sys Nano-ITX is a computer Motherboard form factor first proposed by VIA Technologies at CeBIT in March 2003, and implemented in late 2005 COM Express, a Computer-on-module (COM form factor is a highly integrated and compact PC that can be used in a design application much like an integrated circuit ETX, standing for Embedded Technology eXtended, is a highly integrated and compact (3 ETX, standing for Embedded Technology eXtended, is a highly integrated and compact (3 Pico-ITX is a PC Motherboard form factor announced by VIA Technologies in January 2007 and demonstrated later the same year at CeBIT. PC/104 (or PC104) is an Embedded computer standard controlled by the PC/104 Consortium which defines both a Form factor A motherboard is the central or primary Printed circuit board (PCB making up a complex electronic system such as a modern Computer or Laptop It was announced by VIA Technologies at Computex in June, 2007. VIA Technologies ( is a Taiwanese manufacturer of Integrated circuits mainly Motherboard Chipsets CPUs, and memory, and COMPUTEX Taipei, or Taipei International Information Technology Show ( is a Computer expo held annually at the Taipei World Trade Center in Taipei The motherboard size is 75mm by 45mm, smaller than a business card. The Millimetre ( American spelling: millimeter, symbol mm) is a unit of Length in the Metric system, equal to Business cards are Cards bearing business Information about a Company or Individual. The design is intended for ultra-mobile computing such as a smartphone or UMPC. A smartphone is a Mobile phone offering advanced capabilities beyond a typical mobile phone often with PC -like functionality In Personal computers Ultra-Mobile PC (often abbreviated UMPC) is a small Form factor (a standard size and shape for Tablet PCs and subnotebook/
The prototype boards shown to date include a x86 compliant 1Ghz VIA C7-M processor, 256 or 512 megabytes of RAM, a modified version of the VIA CX700 chipset (called the CX700S)[1], an interface for a cellular radio module (demonstration boards contain a CDMA radio), a DC-DC electrical converter, and various connecting interfaces. See also X86 assembly language The generic term x86 refers to the most commercially successful Instruction set architecture in the history of Personal The VIA C7 is an X86 Central processing unit designed by Centaur Technology and sold by VIA Technologies. Code division multiple access ( CDMA) is a Channel access method utilized by various radio communication technologies
At the announcement, an Ultra-Mobile PC reference design was shown running Windows XP Embedded. In Personal computers Ultra-Mobile PC (often abbreviated UMPC) is a small Form factor (a standard size and shape for Tablet PCs and subnotebook/ [2]
