Dell Precision T3600 System Motherboard, used in professional CAD Workstations. Manufactured in 2012. A motherboard (also called mainboard, main circuit board, MB, mobo, base board, system board, or, in Apple computers, logic board) is the main printed circuit board (PCB) in general-purpose computers and other expandable systems.
The IBM Personal Computer XT was the successor to the original IBM PC, its first home computer. As the specifications were open, many clone motherboards were produced and it became a de facto standard. AT (Advanced Technology) IBM: 1984 305 × 279–330 mm (12 × 11–13 in) Obsolete, see Industry Standard Architecture.
The DTX form factor is a variation of ATX specification [1] designed especially for small form factor PCs (especially for HTPCs) with dimensions of 8 × 9.6 inches (203 × 244 mm). [2] An industry standard intended to enable interchangeability for systems similar to Shuttle 's original "SFF" designs, [ 3 ] AMD announced its development on ...
It was the first major change in desktop computer enclosure, motherboard and power supply design in many years, improving standardization and interchangeability of parts. The specification defines the dimensions; the mounting points; the I/O panel; and the power and connector interfaces among a computer case, a motherboard, and a power supply.
The motherboard is the main component of a computer. It is a board with integrated circuitry that connects the other parts of the computer including the CPU , the RAM , the disk drives ( CD , DVD , hard disk , or any others) as well as any peripherals connected via the ports or the expansion slots .
The rear panel aperture is identical to the EEB and ATX specification and expansion cards mounted on an SSI CEB motherboard appear much the same as they would on an ATX motherboard. To standardize thermal behavior, processor position is defined, including primary and secondary processor identification.
Baby AT motherboard An ATX Form Card, used by later Baby-AT motherboards to allow for USB, PS/2 mouse, and IR connectivity through headers. In 1987, the Baby AT form factor was introduced, based on the motherboard found in the IBM PC/XT 286 (5162) [2] and soon after all computer makers abandoned AT for the cheaper and smaller Baby AT form factor, using it for computers that spanned several ...
The mounting points of microATX motherboards are a subset of those used on full-size ATX boards, and the I/O panel is identical. Thus, microATX motherboards can be used in full-size ATX cases. Furthermore, most microATX motherboards generally use the same power connectors as ATX motherboards, [ a ] thus permitting the use of full-size ATX power ...
