Final answer:
Landlines are telephone lines that transmit signals directly along a wire without the use of radio waves. They use physical cables, such as fiber optic cables, coaxial cables, or Ethernet cables, to transmit signals.
Step-by-step explanation:
Telephone lines that transmit signals from one station to another directly along a wire without the use of radio waves are called landlines. Landlines use physical cables, such as fiber optic cables, coaxial cables, or Ethernet cables, to transmit signals. These cables allow for reliable and secure communication over long distances.
