Is a USB cable considered as an input or output device? Then Explain ?

A USB cable is not considered as an input or output device. It is simply a medium through which data can be transferred between devices. The USB cable itself does not process or manipulate data, it simply serves as a physical connection between devices to facilitate data transfer. Input and output devices are typically hardware components that interact with a computer system to either input data (such as a keyboard or mouse) or output data (such as a monitor or printer).
