Q3. What is the purpose of a subnet mask in IP networking?

Q4. In networking, what does the acronym NAT stand for?

Q5. In the TCP/IP model, which layer corresponds to the network layer in the OSI model?

Answers

A1. HTTPS

Because it uses encryption to protect data exchanged between a user's browser and a web server, ensuring confidentiality and security during transmission.

A2. Transport Layer

Because it manages the flow of data between devices, ensuring complete data transfer and providing error recovery and segmentation.

A3. To distinguish the network portion from the host portion of an IP address

Subnet masks became standard in IPv4 networking with the introduction of classful addressing in the early 1980s, enabling networks to efficiently allocate IP addresses and improve routing.

A4. Network Address Translation

Because it refers to a method used in networking to map one IP address space into another, allowing multiple devices on a local network to share a single public IP address.

A5. Internet layer

The Internet layer in the TCP/IP model is responsible for addressing and routing packets across interconnected networks, essentially fulfilling the OSI model's network layer function, and it includes protocols such as IP, which was first introduced in 1983.
