+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.
Packet delivery is done by 3rd layer as well as 4th layer . But there is a difference between both of them . The network layer ensures source to destination delivery but the the transport layer ensures end to end delivery.
network layer delivery logically communicate between the source-to-destination. while Transport layer delivery logically communicate between PROCESS-to-PROCESS.
Network layer delivery is the logically communicate between the source and destination while transport layer delivery logically communicate end to end connection
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.
Transport, network and link
TCP and UDP are transport layer protocols; the OSI layer is layer 4 (transport)

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.
The Transport layer
The difference between datalink layer flow control and transport layer flow control is the need to keep the different layers of data separate in the flow control option.
It is called Transport layer.
A network layer refers to one of the actual 7 layers. The network layer protocol is actually the system it uses, possibly the order that the layers are done by?
The data link layer handles communication between systems on the same local network. The network layer handles communication between systems on different local networks and allows those packets to be routed between the two. The data link layer would allow two machine on network a to talk to each other or two machines on network b to talk to each other. This communication takes place using the physical/MAC addresses of the machines. The network layer is what allows a machine on network a to talk to a machine on network b using logical address like IP addresses.
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

In order to tell the difference between different data segments the transport layer assigns an identifier to an application. The TCP/IP protocols call this identifier a port number. Each software process that needs to access the network is assigned a port number unique to that host. This port number is used in the transport layer header to indicate to which application that piece of data is associated. Hope this helps!!!
Transport layer is responsible for reliable delivery of information, error correction and so on.
No, usually the Transport layer does acknowledgements.
