Understanding Internet Protocols

The video tutorial explains how data is transmitted over the Internet using protocols. It covers the breakdown of information into packets, the role of IP addresses, and how the Internet Protocol (IP) and Transmission Control Protocol (TCP) work together to ensure data is sent and received correctly. The video also introduces HTTP, which standardizes communication with web servers, and highlights the importance of secure browsing with HTTPS.

What is the primary function of the Internet as discussed in the video?

• To provide entertainment

• To connect people socially

• To transfer information between computers

• To store data permanently

What is the role of DNS in Internet communication?

• To compress data

• To assign IP addresses

• To encrypt data

• To convert domain names into IP addresses

What does the Internet Protocol (IP) primarily do?

• It translates domain names into IP addresses

• It assigns addresses and defines packet layout

• It encrypts data for security

• It compresses data for faster transmission

How does TCP ensure that packets are received in the correct order?

• By encrypting each packet

• By assigning a sequence number to each packet

• By compressing the packets

• By using a single packet for all data

What additional information does TCP add to packets?

• Domain name

• Packet number

• Encryption key

• Compression ratio

What happens if a packet is missing during transmission?

• The data is sent again

• The packet is ignored

• The entire transmission fails

• TCP requests the missing packet

What is the main purpose of HTTP?

• To assign IP addresses

• To encrypt data

• To standardize communication with web servers

• To compress web pages

What does the 'S' in HTTPS stand for?

• Simple

• Secure

• Speed

• Standard

Why is it important to see 'HTTPS' in a URL?

• It shows the website is secure

• It indicates the website is fast

• It means the website is popular

• It suggests the website is free

What does HTML stand for?

• Hypertext Markup Language

• Hyperlink Text Management Language

• Hyperlink Markup Language

• Hypertext Management Language
