Internet Protocol Hierarchy

Write two things you learned from this video.

What is the primary function of the Internet Protocol (IP)?

• To provide reliable ordered packet delivery

• To enable communication between computers on the internet

• To synchronize files between computers

• To manage email protocols

Which protocol is considered part of the Internet Protocol Suite and provides reliable ordered packet delivery?

• UDP

• TCP

• HTTP

• SMTP

What is the main purpose of arranging protocols in a stack?

• To ensure each protocol can operate independently

• To duplicate functionality across protocols

• To make protocols more complex

• To separate concerns and avoid duplication

Which layer of the Internet Protocol stack does the IP protocol reside in?

• Network-specific layer

• Application layer

• Transport layer

• Internet layer

What is the role of the application layer in the Internet Protocol stack?

• To allow applications to use lower-level protocols

• To provide network-specific data transfer

• To implement operating system protocols

• To manage IP addresses

Which protocol is known for not providing reliability or ordering?

• FTP

• HTTP

• UDP

• TCP

Why is it difficult to change protocols like TCP?

• They are implemented at the application level

• They require updates to all operating systems

• They are not widely used

• They are not part of the Internet Protocol Suite

What is a benefit of having application protocols above the operating system?

• They are harder to distribute

• They require operating system changes

• They are less flexible

• They allow easier innovation and distribution

Which protocol is used for web page delivery and relies on TCP for reliable delivery?

• SMTP

• FTP

• HTTP

• UDP
