PCIe (Peripheral Component Interconnect Express) is an I/O bus used to connect devices to a computer's motherboard. It is a low-latency, high-bandwidth interface standard designed to transfer data between a central processing unit (CPU) and I/O devices such as graphics cards, storage, network adapters, and other devices.
PCIe is widely used in modern computers and servers. It provides high data transfer rates because it operates on a series of parallel channels called "lines". The PCIe bus has different versions with different line counts and transmission speeds, such as PCIe 3.0 and PCIe 4.0.
The PCIe bus also supports hot connection and disconnection of devices without rebooting the system. This means that the devices can be connected or disconnected during the operation of the computer, which facilitates the expansion and maintenance of the system.
PCIe is the main interface for connecting expansion cards and devices to modern computers and provides fast and efficient data transfer between system components.
