Correct option is A
A
domain name is a human-friendly text form of an IP address. It is used to identify resources on the internet in a way that is easy for people to remember and use. For example, instead of remembering a complex IP address like "192.168.1.1", a domain name like "www.example.com" is used, which is much easier to understand and use.
Important Key Points:
1.
Human-friendly format: Domain names are easier for humans to remember compared to numeric IP addresses.
2.
DNS (Domain Name System): The domain name is translated into an IP address using DNS, allowing users to access websites without remembering complex IP addresses.
3.
Simplifies Access: It simplifies accessing resources, websites, and services on the internet.
4.
Structure: Domain names typically consist of a name (e.g., example) and a domain extension (e.g., .com, .org).
5.
Uniqueness: Each domain name is unique, corresponding to a specific IP address to ensure accurate routing of internet traffic.
