Persistence timer- a timer in TCP that is used prevent deadlock Piggybacking- the inclusion of acknowledgement on a data frame Pipelining- sending several packets or frames before news is received concerning previous ones Retransmission time out (RTO)- the expiration of a timer that controls the retransmission of packets Round-trip time (RTT)- the time required for a datagram to go from a source to a destination and the back again Segment- the packet at TCP layer, also the length of the transmission medium shared by devices Selective Repeat- an error-control protocol in which only the frame in error is resent Sequence number- the number that denotes the location of a frame or packet in a message Sliding window- a protocol that allows several data units to be in transition before receiving an acknowledgement Stop and Wait- a protocol in which the sender sends one frame, stops until it receives conformation from the receiver and then sends the next frame Questions What is the difference between a connectionless and a connection oriented protocol? o A connectionless protocol sends the data in chunks with no relation between each, no flow control, error control, or congestion control. A connection-oriented protocol begins with an established connection; data can only be transferred once this connection is made. Must be torn down after the data is exchanged.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
