USB (Universal Serial Bus) cables are used to connect devices to a computer. The cables are typically used to transfer data between devices, but can also be used for charging and for providing power. USB Type C is the newest type of USB cable, which is smaller and faster than previous versions, making it ideal for connecting devices such as smartphones or tablets to a computer.
IEEE 1394 (also known as FireWire) is an alternative to USB that is used to connect devices to a computer. The cables are typically used to transfer data between devices, but they can also be used to provide power and to charge devices. Compared to USB, FireWire can transfer data at higher speeds, but due to its size it is not as commonly used in consumer electronics.
