Question

1. List four alternate terms for "physical address".

2. Name the TCP/IP model layers, and map them to the corresponding OSI model

layers.

3. At which TCP/IP model layer(s) do UDP and TCP reside?

4. List five TCP/IP model application layer protocols.

5. You are converting your network to an IP addressing scheme. You assign a junior administrator the task of assigning addresses to your network hosts from the IP address range 202.17.68.0-202.17.68.255. He states that he used every one of the 256 addresses in the range. Which devices on the network will be unable to communicate with other network devices?

Answer 1

Four alternate terms for "physical address" :

1. Binary Address
2. Real Address
3. Memory Address
4. MAC Address (in MS Windows)

TCP/IP layers:
These are the seven layers system that defines the communication function inside a computer.

Here are the seven layers with their positions:

1. Physical Layer
2. Data Link Layer
3. Network Layer
4. Transport Layer
5. Session Layer
6. Presentation Layer
7. Application Layer

This image can help in understanding the different layers of OSI and mapping.

At which TCP/IP model layer(s) do UDP and TCP reside?
Answer: TRANSPORT LAYER

​​​​​​​List five TCP/IP model application layer protocols.
1. IMAP- Internet Message Access Protocol
2. HTTP- Hyper Text Transfer Protocol
3. POP- Post Office Protocol
4. SSH- Secure Shell
5. DNS- Domain Name System

*************************************************

According to the last question, the junior admin has assigned or used every possible address in the range of 202.17.68.0-202.17.68.255.
If you're talking about the device then switches helps us in communicating with network devices over a network, it can also communicate with other network devices as well.

All The Best. Thanks.
