S1: The coming of the computer sparked the need for remotely operated controls. P: It is silicon chip that is at the heart of the remote control. Q: This produces an infra-red beam, which is made up of electromagnetic waves. R: When you press the button on the remote control, the chip sets off an electronic vibration. S: The beam carries a coded signal such as switch on, raise volume, etc. S6: The code is based on binary digits. The Proper sequence should be: A. PQRS B. PQSR C. PRQS D. RPQS

[amp_mcq option1=”PQRS” option2=”PQSR” option3=”PRQS” option4=”RPQS” correct=”option1″]

The correct answer is: PQRS

The silicon chip is at the heart of the remote control. When you press the button on the remote control, the chip sets off an electronic vibration. This produces an infra-red beam, which is made up of electromagnetic waves. The beam carries a coded signal such as switch on, raise volume, etc. The code is based on binary digits.

Option A: PQRS is the correct sequence.

Option B: PQSR is not the correct sequence. The silicon chip is at the heart of the remote control, not the infra-red beam.

Option C: PRQS is not the correct sequence. The silicon chip is at the heart of the remote control, not the button.

Option D: RPQS is not the correct sequence. The silicon chip is at the heart of the remote control, not the code.
