TCP/IP Networking Concepts and Protocols Explained

1. Server Type for Initial Network Client Connection

Which server type would a network client most likely use first when connecting to a network, such as a school network?

DHCP

2. Data Encapsulation Process

What does encapsulate the data? Explain briefly.

The information is converted into data by a specific application. Then, using TCP, the data is divided into segments, and each is assigned a header that includes the source and destination port numbers. Next, the IP protocol header assigns IP addresses (physical and logical). Finally, the Ethernet protocol sends the segments, which are framed with an Ethernet header and trailer containing the source and destination MAC addresses.

3. Identifying Application for Incoming Segments

If an Internet server provides both FTP and HTTP, how does the server know which application should handle an incoming segment?

The destination port number identifies the application that should handle the segment.

4. TCP/IP Application Layer Protocols

What are two application layer protocols of TCP/IP?

• FTP
• SMTP

5. Protocol Used by FTP for File Transfer

Which of the following protocols uses FTP to transfer files over the Internet?

TCP

6. Term for Layer Interaction and Information Formatting

What term describes how the TCP/IP layers are set up and interact to format, assign addresses, and transmit information across a network?

Stack or Protocol Stack

7. OSI Reference Model Layer Order

What is the correct order of the layers of the OSI reference model, starting from the lowest layer to the upper layer?

Physical, Data Link, Network, Transport, Session, Presentation, Application.

8. Matching Data Units to Protocols

Match the following:

• Ethernet - Frame
• IP - Packet
• TCP - Segment

9. Information in an IP Header

What information is contained in an IP header?

IP addresses of source and destination.

10. Transport Protocol Decision for Network Gaming

If you are creating a game that will run on the network, what influences your decision about which transport protocol should be used for the application?

UDP does not interrupt the game to retransmit dropped packets.

11. Protocol for Translating Domain Names

What is the most likely protocol used to translate aula.yalocin.com to 198.133.219.25?

DNS

12. OSI Layer Associated with Wiring Issues

What OSI layer is associated with wiring issues?

Physical Layer (Layer 1)

13. Matching Protocols to Port Numbers

Match the following:

• Telnet - 23
• HTTP - 80
• FTP - 21

14. Client-Server Model Explanation

Explain briefly what the Client-Server model consists of.

A client sends a request to a server, and the server provides a response.

15. Decapsulation Order

If a client has decoded a frame and begun the decapsulation process, what is the correct order of the decapsulation process?

1. Remove the header and Ethernet trailer (Ethernet/Data Link Layer)
2. Remove IP header (Network Layer)
3. Remove TCP header (Transport Layer)
4. Pass data to the application (Application Layer)
