TLD means Top Level Domain.
All domains have a TLD and it is the .net, .com, .org, .biz, .info, etc., portion of a domain name. The term TLD refers to any (or all) of the top-level domain names. You may also see references to Country Specific TLD’s. Country specific domains are controlled by the country (or company authorized by the country) in which they refer. I.E.
- .us TLD for United States,
- .mx TLD for Mexico,
- .uk TLD for United Kingdom,
- .in for India.
All domains in all TLD’s can be accessed, in the same fashion, using a browser.
One of the initial ideas behind differing TLD’s was to distinguish between different organization types to make retrieval of information faster. Though some TLD’s like .edu (for educational organization) require validation for using the TLD, others like .com (for commercial) can and are used for nearly any purpose.
