What is a Domain?

The simplest definition of a computer domain is an Internet location or address. It is simply the permanent location of information on the Internet. Most of today's domains have recognizable names such as www.google.com or www.mydomainchallenge.com. In reality, the letters making up a domain name are substitutes for long strings of numbers that would be difficult or impossible to remember. 

Mydomaincallange.com numerically would look something like this 123.345.567. That is called IP address. IP addresses are neither intuitive nor easy to remember. Use of a domain name that replaces a string of meaningless numbers makes it much more memorable and recognizable.

When you set up a website, you should choose a domain name that clearly lets visitors know what your site, or domain, is about. The most common domains end in .com, .net, .org or .edu. These last three letters are equivalent to showing the "neighborhood" of the domain. For instance, domains ending in .edu are all related to education and most are schools of some type. Domains ending in .org are often organizations such as non-profits, while .com and .net are used by just about anyone who sets up a domain .However .com is still considered most popular and sought after top level domain. Whether or not you've heard the terms "Top-Level Domains" or "TLDs", you've interacted with them every time you type a web address into your  web browser. A TLD is the group of letters that follows the final dot in a domain name. For instance, the TLD for Domain.com is "com". Read more about top level domains.

 Anyone can register a domain name, but to do this you will need to provide the registration company that is called  registrars with some personal details such as name, address, company name and contact information. In most cases, you will register the name for at least one year, and then have to pay a renewal fee to keep beyond that.

Your domain name can contain any letters or numbers you want as well as hyphens ( - ) , and can be up to 67 characters long. Your best bet is to find a short but memorable domain name. You will also need to follow current trademark laws to protect both you and other domain owners.Domains should be between 1 to 63 characters long and must not exceed 255 characters.
