Question 3

What is the difference between TCP and UDP

Accepted Answer

UDP is known as a "connectionless" protocol,as it has very few error-recovery services and no guarantee of packet delivery.UDP is considered to be an unreliable protocol and is often only used for network services that are not greatly affected by the occasional lost or dropped packet.TCP is a "connection oriented" protocol,and was specifically designed to provide a reliable connection between two hosts exchanging data.As part of the TCP protocol,each packet has a sequence number to show where that packet fits into the overall conversation.With the sequence numbers,packets can arrive in any order and at different times and the receiving system will still know the correct order for processing them.
