What else can I help you with?
The what layer in the OSI model arranges data into packets whereas the what layer prepares data for physical transmission?
network data-link
What is the role of the data link layer protocols in data transmission?
The role is to transfer frames to packets
In the transmission control protocol internet protocol architecture what layer is responsible for routing and delivering data packets?
internet
Which osi layer encapsulates data into packets?
network layer
What is the PDU of the network layer?
What is a PDU? corruption of a frame during transmission data reassembled at the destination retransmitted packets due to lost communication a layer specific encapsulation
Which layer of the OSI model encapsulates network layer packets?
Data Link Layer
What Switching breaks data into packets before they are transported?
Packet switching breaks the original data into smaller segments per packet before transmission. This is done in the layer 4 transport layer of the OSI model.
Are data packets only for emails?
If you mean TCP or UDP data packets, then no, they make up every data transmission on the net.
Does the Network layer convert data packets from the Data Link Layer into electrical signals?
NO,IT CONVERTS them into frame
What is stop wait ARQ system?
Basically Its a transmission system that sends packets of data across a link and then waits until it has received signals back from the recipient to show successful transmission of all data packets in that window (set size of a number of data packets). Any packets that don't receive a successful transmission flag are resent before the window progresses to the next set of data packets.
What Protocol Data Unit is employed at the Transport Layer?
PACKETS
What Protocol data units at the network layer of the osi are called what?
Packets
