Internet Protocol Analysis/Transport Layer/Quiz

1

The transport layer provides .

2

The transport layer provides services such as .

3

The Transmission Control Protocol (TCP) is used for transmissions. The User Datagram Protocol (UDP) is used for transmissions.

4

Many of the services attributed to the transport layer are specific to and do not apply to . These include connections, byte oriented data streams, sequencing, reliability, flow control, and congestion avoidance.

5

Transport layer protocols include source and destination to identify process-to-process communication. Sessions are identified using .

6

TCP packets are referred to as . UDP packets are referred to as .

7

UDP has no , and thus exposes any unreliability of the underlying network protocol to the user's program.

8

UDP provides for data integrity, and for addressing different functions at the source and destination of the datagram.

9

UDP is , with delay, and works well in unidirectional (broadcast / multicast) communication.

10

The UDP header includes fields for: .

11

TCP is .

12

UDP is .

13

UDP provides a datagram service that emphasizes over TCP . TCP is optimized for rather than .

14

TCP is a delivery service that .

15

The TCP header includes fields for: .

16

TCP protocol operations are divided into three phases: .

17

TCP connection establishment is performed through .

18

TCP connection termination is performed through .

19

TCP achieves reliable transmission by using .

20

TCP performs error detection through .

21

TCP uses a sliding window flow control process in which .

22

TCP achieves congestion control through .

23

TCP and UDP port numbers range from .

24

The Internet Assigned Numbers Authority has divided TCP and UDP port numbers into three ranges. Port numbers are used for common, well-known services. Port numbers are registered ports used for IANA-registered services. Ports are dynamic ports that can be used for any purpose.
