Breakdown of the Problem

1. Identify the category of devices listed (Keyboard, Microphone, Sensors, Touch Screens).
2. Determine the function of each device to classify them correctly.

Relevant Concepts

1. Input and Output Devices:
   • Input devices are used to send data to a computer system.
   • Output devices receive data from a computer system and present it to the user.

Analysis and Detail

1. Keyboard: This device allows users to input text and commands into a computer, thus it is an input device.
2. Microphone: This captures audio and converts it into a digital signal for processing, making it also an input device.
3. Sensors: These devices detect changes in the environment and send this information into a system, classifying them as input devices.
4. Touch Screens: They register touch and gesture inputs directly, making them input devices as well.

Verify and Summarize

All four devices listed are used to collect data or information that is sent to a computer system. Hence, they all fit into the category of input devices.

Final Answer

d. Input devices
