|
TCP/IP transport layer and OSI layer 4 provide similar services and functions.
|
|
|
TCP/IP network access layer has similar functions to the OSI network layer.
|
|
|
OSI layer 7 and the TCP/IP application layer provide identical functions.
|
|
|
The first 3 OSI layers describe general services that are also provided by the TCP/IP internet layer.
|
Detailed explanation-1: -Explanation: The TCP/IP internet layer provides the same function as the OSI network layer. The transport layer of both the TCP/IP and OSI models provides the same function. The TCP/IP application layer includes the same functions as OSI Layers 5, 6, and 7.
Detailed explanation-2: -The statement which holds true for TCP protocol is a) It provides connection-oriented, reliable packet transfer service. A suite of protocol, used for communication which in return is used to interconnect all other network devices on the internet is called Transmission Control Protocol (TCP) or Internet Protocol (IP).
Detailed explanation-3: -Explanation: The only difference between OSI model and TCP/IP model is that the functions of Presentation and Session layer in the OSI model are handled by the transport layer itself in TCP/IP.
Detailed explanation-4: -Both the TCP/IP and OSI models provide logical ways of networking, as well as the processing of information using a layered system. In both systems, each layer has a specific function.
