Detailed explanation-1: -In terms of bus protocol, PCIe communication utilizes point-to-point switched serial links.
Detailed explanation-2: -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.
Detailed explanation-3: -PCI Express is a serial connection that operates more like a network than a bus. Instead of one bus that handles data from multiple sources, PCIe has a switch that controls several point-to-point serial connections.
Detailed explanation-4: -PCI(Peripheral Component Interconnect) bus is based on ISA (Industry Standard Architecture) Bus and VL (VESA Local) Bus. PCI provides direct access to system memory for the devices that are connected to the bus which is then connected through a bridge that connects to the front side bus.
Detailed explanation-5: -PCIe lanes are used to communicate between PCIe Devices or between PCIe and CPU. A lane is composed of 2 wires: one for inbound communications and one, which has double the traffic bandwidth, for outbound.
