Contents, sizes and terminology edit, further information: Comparison of computer form factors, cases can come in many different sizes (known as form factors ).
The 8-bit PC and XT bus was extended with the introduction of the IBM AT in 1984.
More modern computer cases include a much wider range of variation in shape, form factor and materials, such as brushed aluminium and/or tempered glass which are offered with more expensive cases.
As of 2010 Mini ITX has widely replaced FlexATX as the most common small form factor mainboard standard.On top of that, the fastest video cards are not available for AGP at all.It is technologically superior to the older slots in every way.1, contents, history edit, main article: Bus (computing) History, even vacuum-tube based computers had modular construction, but individual functions for peripheral devices filled a cabinet, not just a printed circuit board.Unfortunately, integrated graphics are very poor performers at 3D graphics.Such a case will also (normally) include the wires needed to connect these ports, switches and indicators to the motherboard.Intel launched their PCI bus chipsets along with the P5 -based Pentium CPUs in 1993.In these modes, both video cards work together on the same game to increase performance.You gain at most a few percent by going from AGP 4X to a faster slot.This class of machines is still known as white box computers.At the time, CD-ROM capacity was larger than the hard disks available, and many business-critical databases were distributed on this media."Data Transmission at High Rates via Kapton Flexprints for the Mu3e Experiment".New video cards may not be compatible with old motherboards and old video cards may not be compatible with new motherboards.External expansion buses edit Laptops generally are unable to accept most expansion cards.There have been many kinds of expansion slots over amsterdam casino 10 euro free the years so most motherboards contain more than one kind of slot.Some cases include built-in I/O ports (such as USB lotto alles fake and headphone ports) on the front of the case.An AGP universal motherboard connector has no keys and therefore can accept any kind of AGP card.You can see a "real" PCI connector in the motherboard picture above.The first company to establish a de facto standard was the Altair 8800, developed, which later became a multi-manufacturer standard, the S-100 bus.
You do have to be a little careful when getting AGP cards because not all AGP cards are compatible with all AGP motherboards.
