PCIväylään

PCIväylän, also known as PCI Express or PCIe, is a high-speed computer expansion bus standard designed to replace the older PCI, PCI-X, and AGP bus standards. It was developed by the PCI Special Interest Group (PCI-SIG) and was first introduced in 2003. PCIe is used for connecting various peripherals, such as graphics cards, storage devices, and network cards, to the motherboard.

PCIe operates on a point-to-point serial architecture, which allows for higher data transfer rates and better performance compared to parallel buses like PCI. It uses lanes, which are pairs of differential signal lines, to transmit data. The number of lanes determines the bandwidth of the connection. For example, a PCIe x16 slot, which has 16 lanes, can transfer data at a much higher rate than a PCIe x1 slot.

PCIe is widely used in modern computers, servers, and other electronic devices. It is also used in various other applications, such as in data centers, where it is used to connect servers to storage devices and network switches. PCIe is known for its scalability, reliability, and high performance, making it a popular choice for a wide range of applications.
