USB 1.x

USB 1.0 and 1.1

Hello fellow of Cyberspace, today I want to talk about USB 1.x let is start

Well for this we going to make a trip in time, to the last millennium and century to be precise the decade of 90. It is invented a new term USB, abbreviation of Universal Serial Bus, is one of the many initiatives of the time to standardize the ports that interact between computers and a whole range of peripherals and electronic devices. For example keyboards, digital cameras, printers, and a large etc. USB has supplanted a wide range of previous interfaces, such as serial ports and parallel ports, as well as separate power chargers for portable devices.

After this introduction we will see the specifications

Previous versions have been on the market sins 1990, but the change was not introduce until 1996 and was a USB 1.0 had a data rate of 1.5 Mbit / s and had two types of terminal that was A that is the famous rectangle and the B some kind of square. Due to its low speed it did not allow extensions or other modifications very few

However, in 1998 came the USB 1.1 that introduced the speed of 12 Mbit / s now this one was very well received, we can see the change in the printers or also the appearance of Legacy-free PC of Microsoft

Even though this may seem strange to us, but not many attempts were made to make smaller connectors there were a couple of attempts with type B but it was not specific and gave connection problems.
