Why do you need a USB cable and how to choose it
You have to charge gadgets, connect them to each other, to stationary computers, photo and video cameras and peripherals every day. Wireless and wired ports are provided for data transfer. The latter is equipped with connectors of a certain format. To connect mobile devices, a USB cable is used, in other words – an adapter.
It saves you when you need to connect a flash drive to a stationary computer. Without a cable, you'll have to crawl under the table and move the system, as the port is often placed at the back. An adapter is also useful when you need to move your modem to a place where the signal is stronger, rather than tethering it to a computer. In addition, the adapter is used instead of a charger - when synchronized with a computer, smartphones, tablets or other gadgets are charged.
The stability and strength of the signal depends on the quality and parameters of this accessory. It happens that the gadget "does not see" the connected wire or the connection suddenly disappears. This is caused by poor quality or incorrectly selected adapter. Therefore, before purchasing a product, it is important to understand the characteristics of USB cables.
Types and parameters of USB cables
The USB interface is classified by:
Standard form or connector: Type A, Type B and Type C.
Port A is used to connect mice and flash drives. The profile of connector B depends on the device it is intended for. A standard wire has the A connector on one end and the B connector on the other end. Thanks to this, it is placed on the sides of the body of very thin devices.
Size: Standard, Small, Micro USB cable. These types are implemented in Type A and Type B connectors. The size of the C port is similar to the small B port.
Length: The longer it is, the weaker the signal and the slower its speed. It is better to purchase adapters up to 3 meters long.
Typically, cords in the mini and micro USB categories differ in the following characteristics, on which the price depends:
Length;
The presence of a ferrite ring - a filter to protect against high-frequency interference;
Shielding – protecting electromagnetic waves from external fields.
