Explanation: 

Detailed explanation-1: -Layer 4 of the OSI Model: Transport Layer provides transparent transfer of data between end users, providing reliable data transfer services to the upper layers. The transport layer controls the reliability of a given link through flow control, segmentation and desegmentation, and error control.

Detailed explanation-2: -The physical layer of TCP/IP describes hardware standards such as IEEE 802.3, the specification for Ethernet network media, and RS-232, the specification for standard pin connectors.

Detailed explanation-3: -Network layer: Handles the routing and sending of data between different networks. The most important protocols at this layer are IP and ICMP. 2. Data link layer: Handles communications between devices on the same network.

Detailed explanation-4: -The Internet Layer of the TCP/IP model aligns with the Layer 3 (Network) layer of the OSI model. This is where IP addresses and routing live. When data is transmitted from a node on one LAN to a node on a different LAN, the Internet Layer is used.
