What is the medium through which data transmits from one device to another, such as cables or fiber optic?

• A. Transmission Media
• B. Transmission Control Protocol/Internet Protocol (TCP/IP)
• C. Transport Layer Security (TLS)
• D. Trivial File Transfer Protocol (TFTP)

Answer: (A)

Transmission media are the physical paths data signals travel between devices, such as copper cables, fiber optic cables, or wireless airwaves. They define how the electrical or optical signals are carried and influence factors like speed, distance, and interference. This is different from protocols or security mechanisms—the other terms refer to rules for communicating (TCP/IP), encrypting data in transit (TLS), or a simple file transfer method (TFTP). So the medium through which data moves from one device to another is the transmission media.
