There are many major components of the motherboard. The basic one to mention is the mounting holes. Without them, your motherboard would be exposed to elements that could ruin it. Two more basic components that are very necessary are the 4-pix ATX12 power connector, which connects the motherboard to the outside power source, and the CMOS battery, which is a battery powered semiconductor chip. The port cluster is where I/O devices will connect to the CPU. There are multiple PCI slots, which send information serially over signal paths that collectively transmit and receive data simultaneously.
For memory, there is the Dual-channel DDR2 memory slots. The North Bridge is connected directly to the CPU. The South Bridge chip is responsible for handling the I/O functions. The SATA host adapter will let you connect an external hard drive for backup. One component that you may not see any more is the floppy drive controller. It is used to reading and writing to a computer’s floppy disk drive.
By upgrading the motherboard alone will give some performance improvement to a computer system. Your I/O systems may not improve. It will depend on the adapters cards they are attached to. There is a need for multiple buses found on a motherboard due to each device being able to connect to its own bus. This will increase productivity. Data will not have to be transferred on a single bus and delay transmission. It is not applicable to replace multiple buses with a single bus due to creating a delay in data transmission. There is a need for a 32-bit bus even though there is a 64-bit bus. The reason for this is the extra
