You probably never heard or read the words Universal Serial Bus, but it is the meaning of the acronym USB, which we simply know as the connection or port of the electronic devices that we have. And there are many that exist.
There has been many types of USB connections in the history of technology, all with different differences, advantages and speeds, which we will explain belowwith information from hard zone.
USB-A and USB-B
For versions 1.0 and 2.9 these had a white line, but starting with version 3.0 the blue color was adopted to differentiate them from previous generations. It has four lines, one of them is its power supply, then we have another for grounding and two data ports.
USB B, on the other hand, has a square shape and has been used for devices like printers and scanners. Outside of its different shape, the specifications are the same as Type A, so it also makes use of a four-pin connector with the exact same configuration.
Mini-USB and Micro-USB, for small devices
Cell phones, digital assistants, MP3 players, and early digital cameras called for smaller ports, so Mini-USB and Micro USB arrived.
The Mini brought an additional pin to the four already used in the rest of the types. The new pin has to do with the OTG or On the Go mode, which serves to mark that the device is subservient to another in terms of power supply.
Regarding the Micro, due to the need to have a power and data port for smartphones, the Micro-USB arrived, which is nothing more than an even smaller version of the USB port.
USB-C
It is the most current type of USB and the most accepted by the different technology organizations in the world. It is characterized by being reversible, that is, we can connect it both on one side and the other without any problem.
USB-C is one of the standards that allows greater power supply and data transmission speed (10 GB per second), in such a way that it is ideal for laptops. Curiously, it hit the market with the third generation of the standard and has no previous versions.
