Q: Devices and methods for sending bits over computer networks make up the ____________.
- modulation
- physical layer
- network layer
- data link layer
Explanation: The “physical layer” of a computer network refers to the hardware and protocols used to move data packets throughout the network. The physical layer is the lowest layer in both the OSI model and the TCP/IP model. Its responsibility is to deal with the physical connection between devices, which includes the transmission and receipt of raw bit streams across a physical medium such as cables or wireless connections.
