The A-type connector has a flattened rectangular interface. Now there are many more types of connectors, but the majority of devices and peripherals still do with A-connector and B-connector interfaces.
When the technology just came into existence, only two connector types were detailed in the original specification – standard A and standard B. The development of the technology means improvement of the speed and performance, there is special forum that supports USB technology’s advancement and adaption known as USB Implementers Forum (USB-iF). What we mostly use these days is USB 2.0 it transfers data at 480 Mbps and supports USB 1.0 and 1.1 devices and cables. The first USB – USB 1.0 – was capable of transferring data at the rate of 12 Mbps and supporting 127 devices. This standard of cable system was developed in mid-90s, when seven technology companies – Microsoft, Compaq, Intel, IBM, Nortel, DEC and NEC – joined their efforts to create a cable system that would make it easier to connect various devices and peripherals to computers.
Let’s get started! ContentsĪs we mentioned above, USB stands for Universal Serial Bus. In the article below I’ll tell you what USB is, describe different types of USB connectors, compare classic USB 2.0 with new USB 3.0 and show you the difference between popular Mini and Micro USB. All major operating systems support USB technology. Nowadays most of the peripherals and devices use USB cables to connect to computers – cameras, printers, scanners, external drives, etc. USB, short for Universal Serial Bus, is a widely used is a cable system that includes physical cables, connectors and communication protocols.
