Q231 (none)

How do TCP and UDP differ in the way they provide reliability for delivery of packets?

A TCP is a connectionless protocol that does not provide reliable delivery of data, UDP is a connectionoriented protocol that uses sequencing to provide reliable delivery.

B TCP does not guarantee delivery or error checking to ensure that there is no corruption of data UDP provides message acknowledgement and retransmits data if lost. C. TCP provides flow control to avoid overwhelming a receiver by sending too many packets at once, UDP sends packets to the receiver in a continuous stream without checking for sequencing

D TCP uses windowing to deliver packets reliably; UDP provides reliable message transfer between hosts by establishing a three-way handshake
