MCQ IN COMPUTER SCIENCE & ENGINEERING

Detailed explanation-1: -PCIe provides lower latency and higher data transfer rates than parallel busses such as PCI and PCI-X. Every device that’s connected to a motherboard with a PCIe link has its own dedicated point-to-point connection. This means that devices are not competing for bandwidth because they are not sharing the same bus.

Detailed explanation-2: -PCI-X buses, like standard PCI, are half-duplex bidirectional, whereas PCIe buses are full-duplex bidirectional. PCI-X buses run only as fast as the slowest device, whereas PCIe devices are able to independently negotiate the bus speed.

Detailed explanation-3: -PCIe. PCIe (PCI Express®) is the more recently introduced standard for connecting devices to computers. It’s software-compatible with PCI but has higher potential bandwidth and greater flexibility than PCI. The PCIe specification is also maintained by the PCI-SIG.

Detailed explanation-4: -Is the speed for PCI slower than PCI Express? Sure, the speed for PCIe is faster than PCI. Take the PCIe x1 as an example, it is at least 118% faster than PCI. It’s more obvious when you compare the PCIe-based video card with a PCI video card, the PCIe video card x16 type is almost 29 times faster than PCI video card.

Detailed explanation-5: -PCI-X increases the clock speed from 66 MHz to 133 MHz, essentially providing a larger, faster pipe for data to flow through. The advantages of PCI-X over conventional PCI are: Double the bandwidth of PCI. Backward compatibility.
