Question

Which of the following is the speed of a single-lane (x1) PCIe v. 3.x link?

1) 2.5 Gbps
2) 5 Gbps
3) 8 Gbps
4) 16 Gbps

Answer 1

The speed of a single-lane (x1) PCIe v. 3.x link is 8 Gbps, which applies to data transfer in both directions as PCIe is full duplex.

Step-by-step explanation:

The speed of a single-lane (x1) PCIe v. 3.x link is 8 Gbps. PCIe, or Peripheral Component Interconnect Express, is a standard type of connection that allows various devices to communicate with a computer's processor. Each version of PCIe has different data rates, and with version 3.x, each lane can transfer data at a rate of 8 gigabits per second. This speed is applicable to each direction, meaning PCIe 3.x is full duplex, allowing for simultaneous data transfer in both directions.
