#7 TCP/IP Protocol Model

What are some of the tasks involved in networking?

• Driving a car

• Cooking food

• Sending emails and web pages

• Painting a house

Why is the concept of layers used in networking?

• To reduce the number of devices

• To divide the problem into manageable subproblems

• To increase the complexity

• To make the network slower

Which layer of the TCP/IP model is responsible for setting up communication between hosts?

• Internet layer

• Transport layer

• Link layer

• Application layer

What does the Internet layer do in the TCP/IP model?

• Handles encryption

• Routes packets across the network

• Manages user authentication

• Controls the physical hardware

Which protocols operate at the application layer of the TCP/IP model?

• Ethernet and Wi-Fi

• TCP and UDP

• IP and MAC

• HTTP and FTP

What is added to each packet at the transport layer?

• Source IP address

• Destination MAC address

• Packet number and port number

• Encryption key

Why are packets numbered at the transport layer?

• To reduce packet size

• To increase transmission speed

• To ensure they are encrypted

• To allow reassembly in the correct order

What information is added at the network layer?

• Source and destination IP addresses

• User authentication data

• Application headers

• Encryption keys

What is the role of the link layer in the TCP/IP model?

• Encrypting data

• Routing packets

• Adding MAC addresses

• Managing applications

What is the significance of the TCP/IP protocol stack?

• It is used for painting

• It is used for cooking

• It allows devices to communicate and transfer data across networks

• It is a type of food
