Question: What is USB 3 and will it work with my older USB 2 devices?
Answer: USB 3 is the third major iteration of the USB (Universal Serial Bus) standard. When it was first introduced, USB provided a truly remarkable improvement in how peripherals connected to a computer. Previously, serial and parallel ports were the norm; each required a detailed understanding of both the device and the computer hosting the device in order to set up the connection properly.
