Ever since the launch of USB Type-C, people have been quite vocal about the benefits of this new USB port. The reversible symmetrical design of USB Type-C sets it apart from its previous counterparts. The reversible design ensures that there is no wrong way of inserting Type-C USB into a port. Along with its innovative design, the technology used in this USB will help in quick charging of your smartphones as well as allow you to transfer data faster. With all the benefits of USB Type-C, people seem to have forgotten all about Type-B USB. So what exactly happened to USB Type-B?
You have been using Type-B USB for decades now without actually referring it to as such. USB Type-B is the connector that is found on the other end of a USB cable, which plugs into a peripheral device such as printers, external hard drives, and smartphones. There are several different sizes and designs of Type-B USB because the peripheral devices vary in shapes and sizes. As the Type-A USB stays the same in all the cables, the USB cables derive their name from the USB-B end of it. Till date, there are around 5 designs of Type-B USB that have been popular. These include:
The Standard-B USB - Initially designed for USB 1.1, the standard-B USB is also used in USB 2.0. This design of Type-B USB is typically used to connect large peripheral devices to the computer, including the scanners and the printers.
Mini-B USB - The mini-B type USB ports are considerably smaller in size when compared to the size of standard-B USB. You will find mini-B USB ports in several older portable devices such as older hard drives, digital cameras, and even smartphones. With the progress in technology and the launch of newer models, the mini-B USB is becoming outdated.
Micro-B USB - The most popular design of Type-B USB today is the micro-B USB. It is marginally smaller than the mini-USB and these micro-USB ports can be found in several latest tablets and smartphones.
Micro-USB 3.0 - If you have ever used USB 3.0 portable drives, the ones that have a blue Type-A USB end, then you know what the design of micro-USB 3.0 looks like.
Standard-B 3.0 - The design of this Type-B USB is very similar to the standard-B USB, the only difference is that the 3.0 Standard-B USB is designed for faster speeds. In most cases, both the ends of this USB are blue in color.
With so many different designs of Type-B USB, it is evident that this USB has seen much non-commercial use in the market for several decades. Another benefit of using type-B USB is that they have been designed with backwards compatibility, which means that even if you plug USB 1.1 in the USB 3.0 port, it will still work albeit slowly.
If Type-B USB has so many benefits, why are people so enthusiastic about using USB Type-C? Well, this is because the Type-C USB comes with all the Type-B benefits as well as a few of its own. The reversible design of this USB means that one cable can be used across all the devices, so no need to keep collecting different USB cables for different devices. What's more, the Type-C USB also allows for bidirectional power, which means that it is possible to charge the host device with the help of a peripheral device. It may take a few years for the Type-C USB to be as popular as the earlier versions, however, there is no doubt that Type-C USB is indeed the future.
