Layer 4 of the TCP/IP Model corresponds to which three Layer(s) of the OSI Model? (Choose three.)
Layer 4 of the TCP/IP model is the transport layer, which is responsible for providing reliable and efficient data transmission between hosts. The transport layer can use different protocols, such as TCP or UDP, depending on the requirements of the application. The transport layer also performs functions such as segmentation, acknowledgement, flow control, and error recovery. 1
The transport layer of the TCP/IP model corresponds to three layers of the OSI model: the transport layer, the session layer, and the presentation layer. The session layer of the OSI model manages the establishment, maintenance, and termination of sessions between applications. The session layer also provides services such as synchronization, dialogue control, and security. The presentation layer of the OSI model handles the representation, encoding, and formatting of data for the application layer. The presentation layer also performs functions such as compression, encryption, and translation. 23
