USB Types- Everything you need to know.

The USB port, cables, and connectors. Now USB stands for universal serial bus. The USB is that the standard that’s used to connect peripherals to a computer and it’s by far the USB types most commonly used port. and therefore the reason why it is so commonly used is that a bit like its name says, it’s universal. The USB port is used to attach many various sorts of devices like keyboards, mice, cameras, printers, scanners, external hard drives, flash drives, and they can even do networking and so much more. And it is also used to charge devices like cell phones. And desktops and laptops will have several USB ports. Now the goal of the event of the USB was to form connecting devices to a computer much easier and this is often done by first making one standard connector, therefore eliminating all the other different sorts of connectors. And second, by making connected devices easier to configure. And third, to supply fast transfer rates. The USB port is additionally hot-swappable so devices are often connected or disconnected without turning off the pc or the device.

The USB also self-configures itself which eliminates the necessity for any extensive configuration or no configuration in the least and additionally to connecting to a computer certain smaller devices are often powered by the USB port without the necessity for extra power cables. the primary USB version was released in 1996 starting with USB 1.0 with later versions released throughout the years. Now USB 1.0 had a transfer speed of 1.5 megabits per second. Then two years later in 1998, USB 1.1 was released and this had a transfer speed of 12 megabits per second. Then within the year 2000 USB 2.0 which is additionally referred to as high-speed USB was released and this had a big speed upgrade from USB 1.1 with speeds of 480 megabits per second.

And then in 2008 USB 3.0 was released and this was referred to as super-speed USB. USB 3.0 boasts speeds of 5 gigabits per second. The high-speed increase was meant for transferring large amounts of data, like backing up to external hard drives. Now subsequent releases of USB 3.0 were later released like USB 3.1 which was released in 2013 and this is often also referred to as super-speed plus USB 3.1 had a transfer rate of 10 gigabits per second which is double of USB 3.0. Then soon after USB 3.2 was released which had a transfer rate of 20 gigabits per second. And in 2019 USB 4 was announced and this features a transfer rate of 40 gigabits per second. Now in addition to the various speeds of USB, there also are different types of USB cables, connectors, and ports that it uses. Now USB cables will typically have two different connectors on each end of a cable.

They will have either A B or type C, with the sort A connector on one end and B and C type connectors on the other end. Now the type A connector is the host connector. this is often a typical rectangular plug that you simply would plug into a computer and computers will have several type-A USB ports. And albeit this is often the oldest connector type, it’s still getting used today Now on the other end of the USB cable you would possibly find different types of connectors, like the type B connector. the type B connector may be a square design with beveled corners on top. Now, this is often also an older connector but it’s still getting used today. this sort of connector is what you’d plug into most printers today, but it is also used on other devices, like external hard drives, USB microphones, and so on. And another version of a type B connector is the mini-B. And a bit like its name says it’s smaller than a kind B connector. The mini-B is used on smaller devices, like older smartphones and digital cameras. But it’s being phased out in favor of even smaller connectors.

And that brings us to the micro–B USB connector. The micro-B is approximately an equivalent width because of the mini-B but it’s about half the thickness, which enables it to plug into even smaller and thinner devices. It’s made to attach to modern smartphones, modern digital cameras, MP3 players, and so on. The micro-B came to call in the year 2007 and its intent was to exchange the mini-B. there’s also the USB 3.0 type b connector. the type B 3.0 has nine pins, compared to four pins within the previous versions.

And this allows for higher transfer speeds and to provide power to a peripheral. Now to make room for the pins the sort B 3.0 is larger and features a different shape than the 1 and 2.0 versions. therefore the type b 3.0 connector won’t fit into devices that are made for USB 1 and 2.0 due to its larger size. there’s also the USB 3.0 micro-B, and this connector is just as thin as the 2.0 version but it’s wider. It’s basically a USB 2.0 micro-B connector but with five additional pins that are stacked on the side of the connector, which doubles the width of a 2.0 micro-B. This connector is used to carry data and supply power to devices like modern external hard drives. and in 2014 USB C was developed and was developed with the USB 3.1 standard. Now this is a thin connector with rounded edges and it’s 24 pins and it easily plugs into a port because it doesn’t have an up and down orientation. Today the USB C are often found on modern smartphones, external hard drives, tablets, and modern desktop and laptop computers. In fact, it’s even wont to charge larger devices like modern laptops. Now as I stated earlier, typically USB cables will have different connectors on each end, with A at one end and a special type on the opposite . However, a typical USB type C cable will have the same connector on each end because type C are often connected to a host, meaning a computer at one end and connected to a different device on the other end.

So, this makes a type C cable convenient because you don’t have to figure out which end goes here because it doesn’t matter, both ends are the same. But even though that’s the typical USB type C cable, you will still find USB cables with A at one end and type C on the other end Now USB ports are color-coded which determines what version they are. Now as I mentioned earlier a computer will have several USB ports and will typically have different versions and that is determined by the computer’s motherboard. So here is an example of the rear input-output panel of a desktop motherboard and as you’ll see it’s several USB ports with different colors. Now USB 1.0 and 1.1 ports will have a white color. Now, these ports are old, slow, and outdated and you will not find them on modern motherboards anymore. USB 2.0 ports will have a black color and albeit they came to call in the year 2000, you’ll still find them on motherboards today. USB 3.0 ports will have a blue color. USB 3.1 will have a teal color. And USB 3.2 ports are red.

Now there also are ports that are called sleep and charge ports and this means that they will still supply power albeit the pc goes into sleep mode, which means you’ll continually charge a device, like a telephone, albeit the pc goes to sleep, which is convenient. And these ports will either have a red, orange, or yellow color.
