Control bus – carries control signals from the processor to other components.Data bus – carries the data between the processor and other components.Address bus – carries memory addresses from the processor to other components such as primary storage and input/output devices.PCI Express: The best type of expansion slot to have in your PC is the PCI Express, also written as PCIe. In this picture, there are three different types of expansion slots: PCI Express, PCI, and AGP. While an expansion bus allows the processor to communicate with peripherals.

Summary: Difference Between System Bus and Expansion Bus is that system bus, also called the front side bus (FSB), is part of the motherboard and connects the processor to main memory. Address bus allows the CPU to talk to a device. It is called that because it’s external to the CPU. Is USB an expansion bus?Įxternal bus or Expansion bus allows the CPU to talk to the other devices in the computer and vice versa. Early computers moved data between devices and the processor at about the same rate as the processor. They allow the flow of data between that device and other devices in and connected to the computer. What is the function of expansion bus?Įxpansion buses are used to connect devices to the motherboard using the motherboard’s data bus. PCI and PCI Express are common expansion buses in computers. An expansion bus typically comprises a series of slots on the motherboard into which cards are inserted.
