FUNDAMENTALS OF COMPUTER

Detailed explanation-1: -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-2: -PCIe, or peripheral component interconnect express, is an interface standard for connecting high-speed input output (HSIO) components. Every high-performance computer motherboard has a number of PCIe slots you can use to add GPUs, RAID cards, WiFi cards, or SSD (solid-state drive) add-on cards.

Detailed explanation-3: -The PCI local bus is a high-performance bus designed for high-speed data transfer. The PCI bus resides on the system board and is normally used as an interconnect mechanism between highly integrated peripheral components, peripheral add-on boards, and host processor or memory systems.

Detailed explanation-4: -PCI Express maintains software compatibility with traditional PCI but replaces the physical bus with a high-speed (2.5 Gb/s) serial bus.
