Its data transfer ranged from 1.5 Megabit per second at Low Speed to 12 Megabit per second at Full Speed.

USB 1.1 was launched in August 1998 and led to broader commercial adoption and public acceptance.

Although it marked USB’s commercial debut, only a few products carried the technology.

USB 1.0 debuted in January 1996 and featured a Full Speed data transfer of 12 Megabits per second.

USB 1.0-RC was a release candidate, as indicated by the initials.

USB 0.99 was another prerelease version that was made known in 1995 but was not set for commercial availability.

Like its predecessors, the release was not made available for commercial markets however, it had a data-transfer rate of 12 Mbps.

USB 0.9 was a prerelease version that debuted in April 1995.

USB 0.8 was another prerelease version, made known although not commercially available within the same year as USB 0.7 was.

Other than this information, not much is known about USB 0.7.

USB 0.7 was a prerelease version of USB, although some considered it the first USB version with a release date of November 1994.

The first version, USB 1.0, was released in 1996, but it was USB 1.1, which debuted in 1998, that gained extensive usage. What’s more, USB-C can now charge laptops (your laptop’s USB-C port must support charging) and, if coupled with Power Delivery (PD), can offer faster charging times.Ī summary: Ajay Bhatt and his team invented USB, whose development began in 1994.

USB data-transfer rates are Low Speed, Full Speed, High Speed, SuperSpeed, and SuperSpeed+. The speed of transferring data between devices is the strongest suit of USB, whose theoretical transmission rate can reach up to 40 Gigabits per second. This ease of use is evident in hot swapping such that you can insert a peripheral into a USB port or remove it, for that matter, without turning off the computer or tweaking some settings.

USB’s primary purpose is to connect devices to computers.

Point of communication, plug and play.
