A top level domain, is more popularly known as a TLD, refers to a domain at the topmost part of the domain name system hierarchy. 

Under the Domain Name System, any Internet address fundamentally consists of four elements: the server prefix, the domain name, the domain suffix and the country code (optional). Thus, a TLD follow the common naming conventions such as “http://www.philwebservices.com”.

For many years, there are only a few top level domains, among the most popular ones include .com (for commerce), .org (for organizations), and .gov (for government). Using these simplified extensions; Internet users can easily determine and associate different types of websites. However, the explosive growth of the Internet came with the corresponding need for top label domain. To address this problem, the International Corporation for Assigned Names and Numbers (ICANN) decided to add a few more top level domains. This includes .biz and .info, just to name a few.  PhilWebServices offers the following TLD’s: .com, .net, .org, .biz, .info.
