Communication between a computer and a keyboard typically involves ____________ transmission.

Correct option is D

The communication between a computer and a keyboard typically uses Simplex transmission, which means that the data flows in only one direction—from the keyboard to the computer. The keyboard sends keystrokes to the computer, but there is no data transmitted back to the keyboard.
Important Key Points:
1. Simplex Transmission - A one-way communication channel where data is sent in only one direction. The keyboard sends signals to the computer, but no response or feedback is sent back.
2. Examples of Simplex - In addition to keyboards, other examples include television broadcasting, where signals are sent from the broadcaster to viewers without receiving anything back.
Knowledge Booster:
• Automatic: This term does not describe a type of transmission mode; it does not apply to keyboard communication.
• Half Duplex: In half duplex communication, data can be transmitted in both directions, but not simultaneously. An example of this is walkie-talkies.
• Full Duplex: In full duplex communication, data can be transmitted in both directions simultaneously. An example of this is telephone communication. Keyboard communication does not require simultaneous bidirectional data flow.
