The answer is E. All of these.
All the devices mentioned in the options can be used to give input as well as display output. Let's go through each option:
A. Headsets: While headsets are primarily used for audio output, they can also include a microphone for audio input, allowing users to give voice commands or participate in audio communication.
B. Touchscreen: Touchscreens are input devices that allow users to interact with a display by touching the screen directly. They can be used to both provide input through touch and display output by showing visual information.
C. Facsimile (Fax): Fax machines, also known as facsimile machines, can both receive and send documents. They receive documents as input and display received documents as output, usually through a printed copy.
D. Audio cards: Audio cards, or sound cards, are primarily responsible for audio output, providing sound to speakers or headphones. However, they can also be used to take input from microphones for recording audio.
Therefore, all of these devices can be used to both give input and display output in various forms.
