Explanation:
Transmission is the process by which a pathogen spreads from one host to another. Diseases or infections are transmitted in many ways. It may be directly transmitted from one person to another, or by certain bacteria, viruses, protozoa, or fungi. There are two different modes of transmission of diseases:
Direct Transmission– This occurs when the pathogen is transmitted directly from an infected person. For eg., if an open wound comes in contact with the blood of a Hepatitis B infected patient, the wounded person might contract the disease.
Indirect Transmission- When the pathogens are not transmitted directly from the infected person but through vectors such as flies, mosquitoes, ticks, dogs, etc., it is known as indirect transmission.

Answer:
transmission line is a specialized cable or other structure designed to conduct alternating current of radio frequency, that is, currents with a frequency high enough that their wave nature must be taken into account. Transmission lines are used for purposes such as connecting radio transmitters and receivers with their antennas (they are then called feed lines or feeders), distributing cable television signals, trunklines routing calls between telephone switching centres, computer network connections and high speed computer data buses.
