Final answer:
BCD input devices are devices that convert decimal numbers into binary format. Some typical BCD input devices include keyboards, barcode scanners, and joysticks.
Step-by-step explanation:
Typical BCD Input Devices
BCD stands for Binary Coded Decimal, which is a way of representing decimal numbers in binary form. BCD input devices are devices that can convert decimal numbers into binary format for processing by a computer. Some typical BCD input devices include:
Keyboards: Keyboards are a common BCD input device that allows users to enter decimal numbers into a computer. Each key on a keyboard represents a character or number that is encoded using BCD.
Barcode Scanners: Barcode scanners are another BCD input device commonly used in retail and inventory management. They can read barcodes, which are encoded using BCD, and convert them into decimal numbers.
Joysticks: Joysticks are input devices used primarily for gaming. They can be used to control the movement of characters or objects in a game, and their inputs can be encoded using BCD.
These are just a few examples of BCD input devices. There are other devices that can be used to input decimal numbers into a computer, depending on the specific application.
