D. Neither A nor B

Answer 1

c. Both A and B

Step-by-step explanation:

The keyboard is indeed the most common input device used to enter data and commands into a computer. However, there are other input devices as well. Here are some examples:

1. Mouse: The mouse is a popular input device used to control the cursor on the screen and interact with graphical user interfaces (GUIs). It allows users to point, click, drag, and scroll, making it easier to navigate and interact with various software applications and operating systems.

2. Scanner: A scanner is an input device used to convert physical documents, images, or objects into digital form. It captures the content of the physical item and creates a digital representation, which can then be saved or edited on a computer. Scanners are commonly used for tasks such as digitizing documents, creating digital copies of photos, or scanning barcodes.

Both the mouse and the scanner serve as input devices, allowing users to input information or commands into a computer system. While the keyboard is the most common input device, the mouse and scanner are also widely used and considered essential input devices in many computing environments. Therefore, the correct answer is option C, "Both A and B."

Answer 2

A mouse and a scanner are both input devices, along with the keyboard. Therefore, the correct answer is C. Both A and B, as they are commonly used to input data into a computer.

Step-by-step explanation:

The student is asking about different types of input devices. An input device is any hardware that allows users to communicate with a computer. The keyboard is indeed one of the most common input devices. However, there are also other devices that serve as inputs to a computer. Options A and B, the mouse and scanner, are both correct examples of input devices. Therefore, the correct answer to this question is C. Both A and B. A mouse allows a user to point and click to interact with the software on the screen, and a scanner converts physical documents into digital format for the computer to process.
