MOTHERBOARD AND ITS FORMS
The largest and most important circuit board in the computer is the motherboard. This is also called as the main board or the system board. The motherboard contains a socket to hold the CPU; the cpu is the component which most processing takes place.
The motherboard is the most complicated piece of equipment inside the case because all devices must be communicates with the CPU installed on the motherboard. All devices in a computer are either installed directly on motherboard or indirectly linked it to by expansion cards. A device i.e. not installed in the motherboard is called a peripheral device.
Now we will discuss something about form factors of motherboard.
Form factor refers to the size and layout of motherboards. As we think not all motherboards are alike. In fact there is a significant difference in the capabilities and size of different motherboard form factors such as Mini –ITX and ATX. This topic covers motherboard size and format.
There are many different sizes of motherboard available, and the size of the motherboard has a direct relation to what type of motherboard will be best suited for particular task. Unfortunately the motherboard manufacturers don’t provide much information about what tasks different sizes of motherboard are best suited for.
The topic will provide you all the information you need to know when picking your next motherboard.
ATX is the most popular motherboard format of the last decade. Since then it has become the most popular standard for motherboards. ATX motherboard has the size of 305mm * 244mm (12in * 9.6in) and will of course fit into any ATX case, although the physical size of the board is too large for Mini ITX and Micro ATX cases.
Because the ATX format is so popular there is a limitless combination of features available for these motherboards. They are made for every chipset and range for barebones budget boards to enthusiast products with multiple PCI Express slots and a buffet of connections. ATX motherboards are suited for any build except for those which require a small size.
Micro ATX motherboard size one of the most popular motherboard formats, Micro ATX is a standard created by intel which has been used for a decade. Micro ATX motherboard can vary somewhat in size because the standard is dictated by maximum of 244mm * 244mm (9.6 inch *9.6 inch). Micro atx motherboards cant exceed the size mentioned above but can be smaller. They must use standard atx mounting locations and so will fit in any Micro ATX or ATX case.
Micro ATX motherboards can be found in virtually any format with support for any socket. They always use the same chipsets ATX boards but are typically lacking a few expansion slot due to their small size. Micro –ATX is suitable for any role but a limited number of expansion slot does not limit their versality. For example, it is often difficult to install a large video card
