DNS translates:
DNS translates domain names into IP addresses. It is a crucial part of the internet infrastructure that allows users to access websites and other online resources using human-readable domain names instead of numerical IP addresses. Here is a detailed explanation of how DNS translates domain names into IP addresses:
1. Domain names:
- Domain names are the human-readable names that we use to access websites and other internet resources.
- For example, "www.example.com" is a domain name.
2. IP addresses:
- IP addresses are numerical addresses assigned to devices connected to a network.
- They uniquely identify each device and allow for communication over the internet.
- For example, an IP address could be "192.168.1.1".
3. Domain Name System (DNS):
- The DNS is a distributed database system that translates domain names into IP addresses.
- It acts as a phonebook for the internet, allowing users to find the IP address associated with a given domain name.
4. Domain Name to IP translation:
- When a user enters a domain name in their web browser, the browser sends a request to a DNS resolver (typically provided by the Internet Service Provider).
- The DNS resolver then starts the process of translating the domain name into an IP address.
5. DNS resolution process:
- The DNS resolver first checks its local cache to see if it has the IP address for the requested domain name.
- If the resolver does not have the IP address, it contacts a DNS root server to request information about the top-level domain (TLD) of the domain name (e.g., ".com", ".org").
- The root server then refers the resolver to the appropriate TLD server.
- The resolver then contacts the TLD server to request information about the authoritative name server for the specific domain name.
- The authoritative name server is responsible for storing the IP address associated with the domain name.
- The resolver contacts the authoritative name server and requests the IP address for the domain name.
- The authoritative name server responds with the IP address, and the resolver stores it in its cache for future use.
- The resolver then returns the IP address to the user's web browser, allowing the browser to establish a connection to the requested website.
6. Benefits of DNS:
- DNS allows users to access websites and other resources using domain names, which are easier to remember than IP addresses.
- It enables the scalability and growth of the internet by providing a hierarchical and distributed system for translating domain names into IP addresses.
- DNS also allows for load balancing and fault tolerance by distributing requests across multiple servers.
In summary, DNS translates domain names into IP addresses, allowing users to access websites and other online resources using human-readable names. It is a crucial part of the internet infrastructure and plays a vital role in ensuring the smooth functioning of the internet.

Answer:

Once an email is sent, the message is broken into pieces called packets.

Explanation:

When an email is sent, the message is divided into smaller units called packets. Each packet contains a portion of the email message along with information about its destination, source, and other necessary details. These packets are then transmitted through the network individually, allowing them to take different routes to reach the recipient.

The process of breaking the message into packets is essential for efficient and reliable data transmission. It allows for better utilization of network resources, as packets can be routed independently based on network conditions. Additionally, packetization enables error detection and correction mechanisms at the packet level, ensuring reliable delivery of the email message.

Once the packets reach their destination, they are reassembled in the correct order to reconstruct the original email message. This process is performed by the recipient's email client or server.

In summary, the division of an email message into packets allows for efficient transmission, error detection, and reliable delivery of the message to the recipient.
