Question

UTP, fiber, and network interface cards are examples of which layer of the OSI model?

a. Physical Layer
b. Data Link Layer
c. Network Layer
d. Transport Layer

Answer 1

UTP, fiber, and network interface cards are examples of components belonging to the Physical Layer (Layer 1) of the OSI model, which deals with hardware devices and the transmission of raw data.

Step-by-step explanation:

UTP (Unshielded Twisted Pair), fiber optics, and network interface cards (NICs) are hardware components associated with the Physical Layer of the OSI model. The Physical Layer, which is the first layer, is responsible for the transmission and reception of unstructured raw data between a device and a physical transmission medium. It includes all the hardware devices, media, and other physical components involved in the actual transmission of data.

Answering your question, UTP, fiber, and network interface cards are examples of a. Physical Layer components of the OSI model. The Physical Layer deals with the physical connection between devices and the electrical signals or optical pulses that carry the data.
