depends on system architecture.
buses
Expansion Buses are used to connect devices to the motherboard and therefore allow the flow of data between that device and other devices in the computer.
Not sayin :P haha
It can have several buses, including the system bus, the PCI Express bus, the PCI bus, the AGP bus, and the outdated ISA bus.
data bus, system bus and host bus.
Via data communication channels called data buses and the motherboard.
The Motherboard.
Buses are the set of wires that carry special information to or from the CPU. There are three types of buses they are: 1. Address buses: these buses carry address given by the CPU from one unit to another in the computer. 2. Data buses: These buses carry data from one unit to other, it is a bi-directional bus i.e the data can be carried in both directions. 3. Control signal: These buses carry control signal from ALU to memory and from memory to alu and then to the output unit.
The motherboard holds most of the essential circuitry needed for the computer. It contains the CPU, the chipset, the buses, the memory, voltage regulators, the BIOS, the CMOS battery, and various controllers. The motherboard may or may not have integrated graphics. If not, the machine will need a separate video card.
If you think of a motherboard as a suburb with houses and buildings (chips) connected by streets ( buses) then it makes a bit more sense
CPU GPU MOTHERBOARD VIDEO CARD SOUND CARD BUSES MEMORY NETWORK CARD CD DRIVE
Some buses have 4 some have 6.
