World of Computer Networking Your CCNA start - Local Area Network (LAN) versus Wide Area Network (WAN)

The video tutorial explains the network layer of the TPAB model, focusing on routing IP packets. It distinguishes between Local Area Networks (LANs) and Wide Area Networks (WANs), providing examples of each. LANs are networks under common administration, typically in the same geographical area, like home or office networks. WANs are interconnected LANs spread across different geographical areas, with the Internet being a prime example. The tutorial concludes with a comparison of LAN and WAN, highlighting their differences and interconnections.

What is the primary responsibility of the network layer in the TPAB model?

• To provide wireless connectivity

• To encrypt data

• To manage user access

• To route IP packets between networks

Which of the following is an example of a Local Area Network (LAN)?

• A satellite communication system

• A home network with multiple devices

• The global Internet

• A network of interconnected cities

What characteristic is common to all devices in a Local Area Network (LAN)?

• They operate on different protocols

• They are under common administration

• They are spread across multiple countries

• They use satellite links

How are Wide Area Networks (WANs) typically structured?

• As a collection of isolated devices

• As a single large network

• As a set of interconnected LANs

• As a network within a single building

Which of the following best describes the Internet in terms of network types?

• A Personal Area Network

• A Local Area Network

• A Wide Area Network

• A Metropolitan Area Network
