You’ve likely encountered numerous different types of cables while using consumer and industrial grade electronics, have you ever wondered what makes them all unique?
We’re here to help us be type A and type B or the oldest U.S. B form factors, and they’ve been in use since 1996. Despite that, U.S.B type A is still commonly used today. And you likely have several of these connectors on your computer. With a few modern exceptions, these implementations feature four pins that have had their potential speeds upgraded over time, beginning at Meagre kilobits per second, and now can reach as high as six hundred twenty five megabits per second.
Disadvantages of type A and B
Their main disadvantage is their relatively large size compared to future USB implementations. Next up was USB, Mini A and Mini B introduced in 2001. These connectors were smaller and were easier to insert correctly, thanks to a defined camphor shape at the Connector.
USB Micro A and B
USB Micro A and B ,micro A is a flat rectangular shape that was later replaced by Micro B, which again has a camphor to indicate which orientation it should be inserted in. As the name suggests, these connectors were even smaller than the prior mini connectors. If you were an Apple user, you’ve likely encountered the lightening cable Apple’s proprietary connector used in their modern iOS devices and accessories.
Lightening in apple
Since 2012, Lightning uses eight pins and is much smaller than Apple’s 30 pin connector that it replaced. Conveniently, lightning was designed to be inserted in either orientation, while earlier versions of USB connectors were notorious for only being insertable in one orientation. And let’s face it, we never got it right. Most recently, there is U.S. B Type C, which is the most recent entry into the universal serial bus family and was introduced in 2014.
USB Type C
USB C , like Lightening can be inserted in either orientation. It is designed to be much more durable than micro micro B and it can deliver much faster transfer speeds it up to 2.5 gigabits per second and much higher power output. Capable of quickly charging higher duty devices such as laptops. Type C can be used for more than just power and data transfer as well.
Type C advantages over other connector types
We may one day see it replace established audio video cables such as HDMI and Display Port, and it may also function as an eventual alternative to Ethernet cables. It sure has been a lot of fun taking a look at USB cables.
