World of Computer Networking Your CCNA start - Why We Should Use Models to Understand Computer Networking

The video tutorial introduces computer networks, explaining how devices communicate using protocols similar to human languages. It covers the importance of understanding these protocols and introduces the TCP/IP and OSI models. The tutorial includes practical activities to demonstrate network connections and protocols, followed by instructions on installing and using Wireshark for network analysis.

Why is it important for network devices to use the same protocol?

• To reduce their size

• To increase their processing speed

• To ensure they can communicate effectively

• To save energy

What analogy is used to explain the need for common protocols in networks?

• Comparing network protocols to different musical instruments

• Comparing network protocols to different languages spoken by people

• Comparing network protocols to different types of vehicles

• Comparing network protocols to different types of food

Which models are discussed to describe how computers communicate?

• Ethernet and Wi-Fi models

• HTTP and FTP models

• OSI and TCP/IP models

• SMTP and POP3 models

What is the purpose of using models like TCP/IP and OSI?

• To design new hardware

• To create new programming languages

• To develop video games

• To understand how devices interact over a network

What tool is suggested for analyzing network sessions?

• Wireshark

• Photoshop

• Excel

• Word
