What does the connector colour on the USB ports mean?

USB means Universal Serial Bus. Put simply, it is a bus, which allows for free communication between various types of electronic devices. For this purpose, USB cables are usually used, which are connected to the appropriate USB ports. These ports make it possible, among others, to connect peripheral devices such as a mouse, keyboard or external drive to our computer.Get more news about Usb Connector,you can vist our website!

Types of USB Ports
It is worth to know, that with the development of technology and progress in the field of electronics, the USB port has undergone a kind of evolution. Thanks to this, today on the market we can distinguish several types of USB. The classic ones include:

USB type A, which was the most popular of the USB types until recently. It has a flat rectangular shape. This type of USB allows to connect a mouse or a portable memory to the PC,
USB type B, which in turn is one of the older types of USB port. It is still used to connect printers. It looks like a square with slightly truncated corners,
USB Type-C, which has been on the market since 2014. It is currently the most popular of the USB connectors. It is characterised by its typically elongated shape. Its undoubted advantage is the fact that the connector is symmetrical, which means that it does not matter which way you insert the plug into the port.
USB Connector – history in a nutshell
The first USB connector appeared on the market in 1998. Since then, a lot has changed. Types of USB plugs differ not only in shape, but also in bandwidth, standards of work, as well as constantly updated nomenclature. Among the most popular we distinguish:

USB 2.0 standard, which appeared on the market in 2000. Today it is already an obsolete technology. Standard 2.0 enables data transfer at the level of 480 Mb/s and works in half-duplex mode, which allows the transfer of information in one direction at the same time.
How do I identify USB port types?
Knowing how USB ports differ from each other, the history of their development and the multitude of applications, it is not difficult to make a mistake when choosing an adapter or cable. USB types can be identified by the shape of the plug, or by looking at the specifications of the port or cable provided by the manufacturer. However, to make it easier for users to distinguish between USB standards without specifications, each type has been colour coded. So, at a glance, you'll know what type of USB connector you're dealing with.
There is also a USB type on the market that is coloured red, yellow or orange. This is the so-called sleep and charge connector. This is not a typical and well-known USB standard. It is only found in USB ports. This colour indicates that the port supports high-current charging or allows you to power your electronic devices with your laptop in sleep mode without turning it on.
