TCP/IP Model Basics

Question 1

What is the primary purpose of the TCP/IP model?

Answer 1

The TCP/IP model is used to standardize communication across the Internet and other networks. It defines how data is transmitted between devices, ensuring reliable communication in real-world networks.

Question 2

What are the four layers of the TCP/IP model?

Answer 2

Network Interface, Internet, Transport, Application

Question 3

What is the function of the Transport layer in the TCP/IP model?

Answer 3

The Transport layer ensures reliable data transmission between devices by managing data flow, error-checking, and ensuring data is received in the correct order (e.g., TCP)

Question 4

What role does the Internet layer play in the TCP/IP model?

Answer 4

The Internet layer is responsible for logical addressing and routing, allowing data to move across different networks (e.g., using IP addresses).

Question 5

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

Answer 5

The Application layer provides services and protocols that allow users to interact with the network through software applications, like web browsers (e.g., HTTP) or email clients (e.g., SMTP).

Question 6

Meaning of TCP/IP

Answer 6

TCP/IP stands for Transmission Control Protocol/Internet Protocol. Basically, it’s a set of rules that make sure data can be sent and received over the Internet. TCP breaks data into smaller pieces (packets) and makes sure everything arrives in order, while IP handles where the data is going, like an address system to get it to the right place.
