Course 2 week 1 Formative Assessment

What is the TCP/IP model?

• A standardized framework for transmitting data over the internet

• A network security protocol

• A database management system

• A web development framework

How many layers does the TCP/IP model have?

• 7

• 5

• 3

• 4

What is the purpose of the Application layer in the TCP/IP model?

• To handle physical transmission of data over the network

• To manage network routing and addressing

• To provide reliable data transmission

• To provide user-level services such as email and file transfer

What is the purpose of the Network layer in the TCP/IP model?

• To provide user-level services such as email and file transfer

•  To provide reliable data transmission

• To manage network routing and addressing

• To handle physical transmission of data over the network

How does the TCP/IP model operate overall? 

•  It transmits data as a single, continuous stream, relying on the physical network to handle any errors or losses 

•  It separates data into packets and transfers each packet individually, ensuring reliable transmission through the use of protocols such as TCP and IP 

• It uses a hierarchical structure to transmit data, with each layer providing specific services and passing the data to the next layer 

• It uses a centralized system to manage and transmit data, relying on a single node to coordinate communication
