Final answer:
The speed of a single-lane (x1) PCIe v. 1.x link is 250 MB/s, which is related to the PCIe interface used to connect components in computers.
Step-by-step explanation:
The speed of a single-lane (x1) PCIe version 1.x link is 250 MB/s. PCIe, which stands for Peripheral Component Interconnect Express, is a high-speed interface standard for connecting components like graphics cards and SSDs to a motherboard. The PCIe 1.x version, being the first generation, has a transfer rate of 2.5 GT/s (gigatransfers per second), which, due to the 8b/10b encoding, results in an effective data transfer rate of about 250 megabytes per second for each lane.
