What else can I help you with?
The IEEE subdivided the datalink layer to provide for environments that need connectionless or connection-oriented services What are the two layers called?
Mac & llc
How do the transport layer Internet services distinguish among traffic to different applications on the same server?
It uses a connectionless protocol only for multiple simultaneous transmissions. It uses multiple ports. - UDP
Which protocol working at the Transport layer provides a connectionless service between hosts?
There are many connectionless protocols depending on which layer of the OSI model you are referring to. An example would be UDP for transport, and IP for routing.
What layer protocal is MEGACO?
Megaco/H.248 is an Application Layer protocol and works on TCP/UDP.
What is called server socket layer?
socket layer is a interface between sender server and the receiving server
When connectionless protocols are implemented at the lower layers of the OSI model?
an upper-layer, connection-oriented protocol or service
Ipv4 is connectionless or connection oriented?
It's neither. IP is a transport layer protocol. Connection/Connectionless imply the network layer. Look up the OSI model. Actually you are correct, but it doesn't just go that far. The definition of connectionless is the ability to send and receive packets without already establishing connectivity between two or more specific entities. IPv4 is connectionless, meaning if I send information via IPv4 I can just send the packets without having to do much more than click "return". Hope this helps.
Which application layer protocol will provide for peer to peer file sharing in a workgroup?
SMB (Server Message Block)
What two options represents layer four addressing in the osi model?
Layer 4 usually uses segments, layer 3 are packets, layer 2 are frames. Layer 4 uses either tcp (SYN and ACKS) and UDP (connectionless) with port numbers
What difference does it make to the network layer if the underlying data link layer provides a connection-oriented service versus a connectionless service?

What protocols do not guarantee delivery of their data but do operate with a very low overhead that conserves network bandwidth?
connectionless protocols - transport layer
Are Layer 2 protocols connectionless or connection-oriented?
They can be both. E.g. MPLS-TP or Connection-Oriented-Ethernet (COE) are connection oriented.
