FUNDAMENTALS OF COMPUTER

Detailed explanation-1: -A PCIe is a high-speed serial computer expansion bus standard that connects devices such as graphics cards, solid-state drives, and network adapters to a computer’s motherboard. PCIe is a newer standard than its predecessor, which was, funnily enough, called PCI. PCEis are everywhere in your computer.

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: -The PCIe bus provides speeds up to 62.5 MB/sec per slot. This speed is sufficient for many PCI cards, but may impact the performance of higher-speed cards (for example, USB 3.0 PCI cards).

Detailed explanation-4: -PCI is a parallel interface whereas PCIe is a serial interface.

Detailed explanation-5: -PCI Express maintains software compatibility with traditional PCI but replaces the physical bus with a high-speed (2.5 Gb/s) serial bus.
