Information is available in two modes: input and output data. While the users provide the input data, the computers give the output data. But the computer's CPU can't compute or produce the output data without the availability of input data. However, providing manual data is highly time-consuming and energy prohibitive. Data storage is the best solution that can help with input data. Users can save the data onto any device, and computers can read the input data from different sources to create and save the output. Storage devices are functional and can connect to the computers either directly or through the network, as preferred.
