Universal Serial Bus (USB) cables transfer data between a computer and a USB device. They are made up of insulated twisted-pair cables, any USB connector on one end, and a rectangular connector on the other that plugs into the computer's USB port. USB cables may be used interchangeably between devices, although some may need device drivers to work properly with the computer.
Types of USB Cables
Kinds of USB Cables include the following:
Low-speed USB cables
Low-speed USB cables transmit data at about 1.5 megabits per second (Mbps).
They have no required impedance, and their wires usually have no shielding.
They are commonly used for input devices such as mice, keyboards, and joysticks.
High-speed USB cables
High-speed USB cables have a data rate of 12 Mbps.
They have better shielding than low-speed cables to withstand the increased voltage.
They can transmit over longer cables and are usually backward-compatible with older USB configurations.
Choosing USB Cables (Buying tips)
Length: Choose a USB cable that allows enough room to operate your device while connected to the computer. Most available cables are five to six feet long, which should do for most applications. If you need a longer cable, consider getting an extension cable for cascading different cables. Insulation: Choose a USB cable with a thick PVC insulating cover. Make sure it does not tear or fray easily.
