Storage devices are considered both input and output devices because they can receive data (input) from a computer system to store it for later use, and they can also provide data (output) back to the computer system when requested. For example, when you save a document to a hard drive, the hard drive acts as an input device by receiving the data. When you retrieve that document later, the hard drive acts as an output device by providing the data back to the computer system for display or processing.
An SD card is considered a storage device rather than an input or output device. It is used to store data such as photos, videos, and documents. When data is written to an SD card from a computer or camera, it is considered an output action, and when data is read from an SD card into a device, it is considered an input action.

Here are the input and output devices in a supermarket and their roles:Cameras - These are input devices for the store security system. Their security office has computers, I/O storage devices (often hard drives), and monitors for output devices so their loss management team can watch suspicious customers.Checkout lights - While not a computer component, these are output devices that let the customer know if the register is open or closed. If they are flashing, then that signals that a manager is needed, or that the cashier has left to get the manager or do a price check.Keypads - These are input devices used for the cashier and/or the customer to enter data. For the cashier or manager, it is to enter price overrides and to enter prices or SKU codes of unmarked merchandise. For the customer, it is for entering their pin number.Loss management sensors - These are primarily input devices in that they use RF signals to detect if there is unpaid merchandise. But they are also output devices when a detection is made, since they sound alarms and flash lights to alert the possibility of theft.Price scanner - This is an input device that reads the UPC codes so the prices can be determined.Receipt printer - This is an output device that prints the receipts for the customers. This could be a part of a cash register or a separate device that is attached to a point of sale system or computer.Scales - These are primarily input devices in that they input data from the weight of the products. They are also used as security devices in self-check registers.
