The architecture of a PCIe differs from past serial buses due to its topology. PCIe was designed to replace older bus standards (PCI, PCI-X, etc.). You may recognize PCIe slots very easily by the lines on a motherboard that typically resemble Lego blocks. This interface allows for the host (motherboard ) to communicate with whichever peripheral that is slotted into them (endpoint). PCIe, or Peripheral Component Interconnect Express, is a standard interface that connects components to a computer. This blog will explore the PCIe interface, what they do, and how they have evolved throughout the years. But how do these components have the capability to read, write, and communicate with the motherboard and CPU/Socket? The answer is simple, through the PCIe interface.
The same goes for any storage, wi-fi cards, and RAID cards. Need to fit a GPU? Slot it right into the dedicated PCIe slot that is designed on the motherboard.
Adding peripherals to a computer is a simple task.
