Chapter 5 Fundamentals of TCP/ IP Transport and Applications Flashcards
The process by which a connection-oriented protocol creates a connection. With TCP, a connection is established by a three-way transmission of TCP segments.
Connection Establishment.
The process of discovering whether a data link level frame was changed during transmission. This process typically uses a Frame Check Sequence (FCS) field in the data link trailer.
Error Detection.
The process of noticing when some transmitted data was not successfully received and resending the data until it is successfully received.
Error Recovery.
The process of regulating the amount of data sent by a sending computer toward a receiving computer.
Flow Control.
Which Transport layer protocol provides error recovery and flow control?
TCP.
Which Transport layer protocol has a low overhead and therefore provides faster transmission speeds?
UDP.
Which Transport layer protocol is most suitable for voice over IP (VoIP) and video over IP and why?
UDP as no error recovery is required and transfer speed is the primary concern.
A multiplexing socket contains what three things?
An IP address, a transport protocol and a port number.
dynamic port numbers start at which number?
1024.
What is the function of Multiplexing?
It ensures that data is delivered to the correct applications.
A protocol that requires an exchange of messages before data transfer begins, or that has a required preestablished correlation between two endpoints.
A Connection Oriented Protocol e.g. TCP.
A protocol that does not require an exchange of messages and that does not require a preestablished correlation between two endpoints.
A Connectionless Protocol e.g. UDP.
Quality of Service considers which four competing characteristics?
Bandwidth, Delay, Jitter & Loss.
URL is an acronym for what?
Uniform Resource Locator.
