Which layer includes the physical transmission medium (cables or wireless media) that any network must use to send and receive the signals that constitute the physical expression of networked communications?

Answer 1

The correct answer to the following question will be "Physical Layer".

Step-by-step explanation:

• The lowest layer of the OSI reference model is the physical layer. It's in charge of having to send bits from one desktop to the next.
• This layer isn't acquainted with the interpretation of the parts and is concerned with setting up a physical wireless connection and sending and receiving signals.
• This layer relies on aspects of the hardware, such as wires, transmitters, and network interface tokens.

Therefore, it will be the right answer.
