FUNDAMENTALS OF COMPUTER

Detailed explanation-1: -What is PCIe or PCI Express? PCIe is short for “peripheral component interconnect express” and it’s primarily used as a standardized interface for motherboard components including graphics, memory, and storage.

Detailed explanation-2: -PCI is a parallel interface whereas PCIe is a serial interface. PCI uses individual buses for each of the devices connected to it instead of a shared one like what PCIe uses. The difference in speed between standard PCI interface and 16 slot PCIe is large.

Detailed explanation-3: -Peripheral Component Interconnect (PCI) is a local computer bus for attaching hardware devices in a computer and is part of the PCI Local Bus standard. The PCI bus supports the functions found on a processor bus but in a standardized format that is independent of any given processor’s native bus.

Detailed explanation-4: -Peripheral Component Interconnect, or PCI, is the most common way to attach add-on controller cards and other devices to a computer motherboard. This type of connector originated in the early 1990s, and is still in use today. Presently, there are three main PCI motherboard connectors (usually referred to as “slots".)
