or
Q: In the five-layer TCP/IP paradigm, which layer is concerned with connections and cabling?
- The physical layer
- The application layer
- The transport layer
- The network layer
Explanation: The five-layer TCP/IP model does not have a one-to-one mapping with the OSI model; nevertheless, if we examine the physical layer of the OSI model, it correlates to the lower-level functions such as cabling and connections. The OSI model does not have a one-to-one mapping with the TCP/IP model. In the TCP/IP model, these functions are often included in the Network Interface layer, which is sometimes referred to as the Link layer or the Data Link layer. Unlike the OSI model, which divides its levels specifically into five categories, the TCP/IP model does not.
