2The motherboard is the most important component of the computer system.• It is a Printed Circuit Board(PCB) where all components of the system are connected• Components are connected by means of slots, connectors and sockets• In the motherboard there is a series of chipsets that are all part of the motherboard
3Types of MotherboardsIntegrated Motherboards• This arrangement saves a lot of space inside the system• Have all the ports for connecting various devices mounted on the board; peripheral device slots, input output ports, serial and parallel ports• Integrated motherboards are cheaper in cost compared to other but if an individual component of the motherboard fails the entire board may need to be replaced which is costly
4Non-Integrated Motherboard• This motherboard does not support connecting devices• All the input output ports for devices and other controllers are attached to the system using expansion boards ,which uses more space in the casing.• This type is more costly compared to an integrated board
5There are three form factors that tell the differences between motherboards. These factors refer to its physical shape, layout and positioning of the components on it.1. Obsolete Form Factor2. Modern Form Factor3. Proprietary Form Factor
61. Obsolete Form FactorThis factor consists of Advanced Technology(AT), Baby ATand Low Profile Extended (LPX)Advanced Technology (AT)• Very large and no longer used by present-day motherboard manufacturers• Does not fit into most of the popular system cases• Its size makes installation and troubleshooting difficult• It supports a maximum of 7 slots
7Baby AT• Fits into most of the system cases• The motherboard is 8.5 inches wide and approx. 13 inches long• It supports a maximum of 8 slotsLow Profile Extended• This is used for slim line or low profile cases. It has a small size and low cost• It supports a maximum of 8 slots• Difficult to expand or upgrade• They have cooling problems and the machine experiences automatic shut downs
82. Modern Form FactorConsists of ATX ,NLX ,FLEX ATX form factors Advanced Technology Extended (ATX)• The most common and most popular form factor meaning most modern cases are made to match.• Makes use of the best features of both AT and LPX form factors.New Low Profile Extended(NLX)• Designed keeping in mind easier assembly, reduced cost, space efficiency and flexibility.• Usually used in low end PC’s because of limited expandability but is still quite popular because of its size and affordability.
9FLEX ATX• Derived from the ATX form factor ,uses many of the same benefits.• Reduces the size of the motherboard ,resulting in smaller system designs.• Backwards compatible with ATX motherboards.3. Proprietary Form FactorBalance Technology Extended(BTX)• Intended to replace ATX.• Designed to further reduce problems caused by power consumption and heat production.
