Question

What is the speed of a single-lane (x1) PCIe v. 1.x link?

1) 2.5 Gbps
2) 5 Gbps
3) 8 Gbps
4) 10 Gbps

Answer 1

The speed of a single-lane (x1) PCIe v. 1.x link is 2.5 Gbps, with PCIe being a high-speed serial computer expansion bus standard, and version 1.x specifically providing a transfer rate equating to this speed.

Step-by-step explanation:

The speed of a single-lane (x1) PCIe v. 1.x link is 2.5 Gbps. PCIe, which stands for Peripheral Component Interconnect Express, is a high-speed serial computer expansion bus standard used to connect hardware devices in a computer. The version 1.x of PCIe provides a transfer rate of 2.5 gigatransfers per second (GT/s), which translates to approximately 2.5 Gbps when taking into account the 8b/10b encoding used, where for every 10 bits transmitted, 2 are used for encoding purposes.
