Question

Which statements are true about TCP and UDP? (Choose all that apply.)

a. TCP is generally faster than UPD.
b. TCP guarantees delivery and UDP does not.
c. UDP is used on the local network but not on the Internet; TCP works on both the local network and the Internet.
d. TCP establishes a session between source and destination before it sends data, and UDP sends data without first establishing a session.

Answer 1

TCP guarantees delivery and UDP does not. UDP is used on the local network but not on the Internet; TCP works on both the local network and the Internet. TCP establishes a session between source and destination before it sends data, and UDP sends data without first establishing a session. The correct answer is A.

Step-by-step explanation:

b. TCP guarantees delivery and UDP does not.

c. UDP is used on the local network but not on the Internet; TCP works on both the local network and the Internet.

d. TCP establishes a session between source and destination before it sends data, and UDP sends data without first establishing a session.

TCP guarantees delivery of data and establishes a session before data transfer, which UDP does not guarantee or require. UDP is used both on local networks and the Internet, and while TCP provides reliable communication, it is not faster than UDP.

The question concerns the differences between TCP (Transmission Control Protocol) and UDP (User Datagram Protocol), which are both transport layer protocols used in network communications. The accurate statements regarding TCP and UDP are:

TCP establishes a session between source and destination before it sends data, and UDP sends data without first establishing a session. This means TCP is connection-oriented, while UDP is connectionless.
