The transport layer provides additional function to compensate for the limitations and impairments of the network layer, in order to meet requirements (e.g. QoS) of the upper layer. For example in TCP/IP, IP provides only best effort service. To provide the reliable service required by some applications - that is, to compensate for the shortcomings of best effort service - TCP establishes connections and implements flow control and congestion control on an end-to-end basis. Answer Actually, it is, just not through normal tools. Special programming is required to access the upper layers of TCP.
I don't believe it's possible to transmit data without some sort of transport layer.
It is called Transport layer.
There is a good descrition of the network layer and TCP in the related link. NO. In general TCP and UDP are transport protocols that operates in Layer 4 Transport Layer
Transport, network and link
TCP and UDP are transport layer protocols; the OSI layer is layer 4 (transport)
Transport layer is responsible for reliable delivery of information, error correction and so on.
No, usually the Transport layer does acknowledgements.
Physical, Data link and Network layers make the Network Support layers.
All people seem to need data processing, or Please do not through sausage pizza away Application, presentation, session, transport, network, data link, and physical. or Physical, data link, network, transport, session, presentation, and Application.
delivers data reliably across the network using TCP
transport layer processes occur between the applicaitoin layer and internet layer of the TCP/IP and between the session layer and network layer of the OSI model.
+network layer logical communication between hosts +transport layer: logical communication between processes ex: we have 2 house and one house have 12 room. kids in the houses send letter together. network layer: only send letter between the houses transport layer: it make sure that the letter be sent to right the room in the house.
