Internet Structure and Protocol Layering Quiz

What is the internet?

• A collection of interconnected networks, routers, cables, and hardware spanning the world

• A service that runs on the internet

• A wide area network

• A protocol stack consisting of four layers

What is the difference between the internet and the world wide web?

• The internet is a collection of interconnected networks, while the world wide web is a service that runs on the internet

• The internet is a wide area network, while the world wide web is a protocol stack consisting of four layers

• The internet is a service that runs on the world wide web, while the world wide web is a collection of interconnected networks

• The internet and the world wide web are the same thing

Which layer of the TCP/IP protocol stack is responsible for addressing packets and routing them across the network?

• Application layer

• Transport layer

• Internet layer

• Link layer

What is the advantage of protocol layering?

• It helps to reduce a complex problem into smaller subproblems

• It allows devices from different vendors to work together

• It ensures successful networking between devices

• It simplifies the process of networking computers together

What is the purpose of the link layer in the TCP/IP protocol stack?

• To facilitate the transmission of binary via any media

• To establish an end-to-end connection between two hosts

• To address packets and route them across the network

• To handle network applications such as web browsers and email programs

What is the role of the DNS (Domain Name System) in the world wide web?

• To map domain names to IP addresses

• To establish an end-to-end connection between two hosts

• To address packets and route them across the network

• To handle network applications such as web browsers and email programs

What is the purpose of the transport layer in the TCP/IP protocol stack?

• To facilitate the transmission of binary via any media

• To establish an end-to-end connection between two hosts

• To address packets and route them across the network

• To handle network applications such as web browsers and email programs

What is the purpose of the application layer in the TCP/IP protocol stack?

• To facilitate the transmission of binary via any media

• To establish an end-to-end connection between two hosts

• To address packets and route them across the network

• To handle network applications such as web browsers and email programs

Why do we need both MAC addresses and IP addresses?

• MAC addresses identify the physical devices on a network, while IP addresses identify the location of the devices

• MAC addresses identify the location of the devices, while IP addresses identify the physical devices on a network

• MAC addresses are used for communication within a local area network, while IP addresses are used for communication between different networks

• MAC addresses and IP addresses serve the same purpose and can be used interchangeably
