Top-Level Domain (TLD)

A top-level domain (TLD) is the last segment of a domain name, located to the right of the dot. It represents the highest level in the hierarchical domain name system (DNS) structure. TLDs are used to categorize and group websites based on their purpose, location, or organization.

Example of a TLD:

a).com

Explanation:

The correct answer is option 'A' - .com.

- The TLD ".com" stands for "commercial" and is the most popular and widely recognized TLD. It is primarily used for commercial and for-profit websites.
- The TLD ".com" is often associated with businesses and is commonly used by companies worldwide to establish their online presence.
- Many well-known websites and brands, such as Google, Facebook, and Amazon, have domain names that end with ".com".

Other TLDs:

b).net

- The TLD ".net" stands for "network" and was initially intended for network infrastructure and internet service providers.
- However, it is now used by a wide range of websites and organizations, including businesses, non-profit organizations, and personal websites.

c).www

- "www" is not a TLD but a subdomain prefix commonly used to indicate the World Wide Web. It is not a part of the TLD but rather a convention to specify the web server.

d).http

- "http" is not a TLD but a protocol prefix (Hypertext Transfer Protocol) used to communicate between a web browser and a web server.

e).ftp

- "ftp" is not a TLD but a protocol prefix (File Transfer Protocol) used for transferring files between a client and a server.

In summary, the example of a TLD among the given options is ".com". TLDs play a crucial role in identifying the purpose and nature of a website's domain name.
