TCP and UDP Protocols Overview

The video tutorial provides an in-depth comparison of TCP and UDP protocols, highlighting their pros and cons. It includes practical examples of building TCP and UDP servers using Node.js. The tutorial also discusses the applications of these protocols in different scenarios, emphasizing the importance of choosing the right protocol based on specific needs.

What are TCP and UDP primarily used for?

• Data storage

• Image processing

• Network communication

• Video editing

Which feature of TCP ensures that data is received in the correct order?

• Connectionless

• Stateless

• Ordered packets

• No congestion control

What is a major disadvantage of TCP?

• No security

• No guarantee of delivery

• No acknowledgment

• Larger packets

Which protocol is faster due to its lack of acknowledgment and ordering?

• FTP

• TCP

• UDP

• HTTP

What is a key advantage of UDP over TCP?

• Connection-based

• Smaller packets

• Guaranteed delivery

• Stateful

In which scenario is UDP preferred over TCP?
