There is no device today that does not have one or more connections via USB cables. Personal computers, smartphones and tablets are only the most common. Not everyone knows what they exist for different models and types of USB cables and that each has its own specific characteristics
What are USB cables
The USB cable, which stands for Universal Serial Bus, an interface dthe communication and represents an industry standard developed in 1996 to standardize the connection of computer peripherals.
The original purpose of USB cables was solely to exchange data and information, today, however, they are also used for Reload the single devices, thanks to the ability to transfer electricity.
Another of the characteristics of the USB system compared to the previous ones is the so-called functionality Hot Swap, which allows you to connect and disconnect peripherals without having to restart your computer.
The most common models of USB cables
There are different types of USB cables, which differ from each other in the type of connector, in the speed of data transfer and in the function they perform.
The USB type A cable the most common, characterized by the flat and rectangular opening. the cable used by PC peripherals (mouse, keyboard), modern TVs and chargers. It can be used both for data transfer and for charging.
The USB type B cable it has a square shape with rounded corners on one side and connects peripherals such as printers or scanners to the computer, which have autonomous power supply.
The Mini USB cable a little smaller than the previous one and is mainly used with devices such as old digital cameras, old smartphone models and some external hard drives.
The Micro USB cable the one present in most smartphones and tablets to charge the battery. All mobile phone manufacturers have chosen to equip their devices with the Micro USB socket, except for Apple, which uses its connector Lightning.
Other types of more modern USB cables
The most recent standard for USB cables is type C, characterized by transfer speed some data very pi high and more energy production than most common USB cable models.
It is possible to purchase these USB Type-C cables on RS components, an electronics store among the best supplied, which offers different models to choose from, depending on the customer's needs.
The cables Usb C they have more or less the same dimensions as the Micro Usb B, but one of their peculiarities is the possibility of being inserted in any direction, so it is impossible to mistake the direction of insertion.
The other advantage of this type of socket which also allows thebi-directional power supply, i.e. it is possible to recharge both the device and any device host, through a peripheral, reaching a speed of 40 Gbps on four rows with 10 Gbps per row.
Usb type sockets TO is B I'm backward compatible although sometimes this leads to a decrease in data transfer speed. Those of type Cinstead, they are not, but it is possible to overcome this problem by using specific adapters.
LUsb 3 another of the latest standards on USB cables and currently allows the highest transfer rate. You can copy, transfer and move files much faster and you can also watch a full HD video, without necessarily having to copy it to your PC.
It is about to be introduced on the market lUsb 4, also backwards compatible with previous standards and with a data transmission capacity of up to 40 Gbps.
