Motherboard Components Used for Communication Among Devices The data bus System of pathways used for communication and the protocol and methods used for transmission

The Bus and Bus Lines

Bus Data path side Can have multiply buses on a system 64 bits Width of bus Can have multiply buses on a system The bus that communicated with the CPU is the System, Host, Memory, front side, external bus. 64 bits

Data Bus Motherboards have more than one type of bus: -System bus (cpu, memory, chip set) -AGP bus (video) -PCI bus (expansion cards)

System Clock

Clock Speed Of Motherboard Of CPU Measured in megahertz (MHz) Ranges from 400MHz to over 1000MHz Of CPU Measured in gigahertz (GHz) Ranges from 166MHz to over 4GHz
