What Is a Bus Expander

Bus expanders are computer boards or cable systems that connect to other interface boards, using only one I/O slot while remaining compliant with the bus standard. Bus expanders allow increased bus loads across all buses while maintaining the integrity of legacy firmware and software.

What is the difference between PCIe bus and expansion bus?

Peripheral Component Interconnect Express (PCIe or PCI-E) is a serial expansion bus standard for connecting a computer to one or more peripheral devices. PCIe provides lower latency and higher data transfer rates than parallel busses such as PCI and PCI-X.

What are the various types of expansion bus architecture used in the PCS?

• ISA – Industry Standard Architecture.
• EISA – Extended Industry Standard Architecture.
• MCA – Micro Channel Architecture.
• VESA – Video Electronics Standards Association.
• PCI – Peripheral Component Interconnect.
• PCI Express (PCI-X)
