Transmitted data segments are tracked.

|
Destination devices reassemble messages and pass them to an application.

|
|
Received data is unacknowledged.
|
Detailed explanation-1: -Explanation:TCP:· Provides tracking of transmitted data segments· Destination devices will acknowledge receiveddata. Source devices will retransmit unacknowledgeddata. UDP· Destination devices will not acknowledgereceived data· Headers use very little overhead and causeminimal delay.
Detailed explanation-2: -UDP is commonly used in time-sensitive communications where occasionally dropping packets is better than waiting. Voice and video traffic are often sent using this protocol because they are both time-sensitive and designed to handle some level of loss.
Detailed explanation-3: -Both UDP and TCP carry port number information in their headers. Both protocols also provide for a checksum field to assure data integrity, although it is sometimes not used by UDP. Finally, both TCP and UDP headers have a length field, which prevents incorrect or runt segments from circulating through the network.
