A domain must be unique (for example there can only be one single Yahoo.com) and must be registered with a domain registrar (ie. NameCheap); while for sub domains, users can freely add it on top of the existing domain as long as their web host provide the service. Some would say sub-domains are the ‘third level’ domains in the sense that they are simply “sub folders” under the domain root directory, normally used to organize your website content in different languages or different categories.

The hierarchy of domains descends from the right to the left label in the name; each label to the left specifies a subdivision, or subdomain of the domain to the right. For example: the label example specifies a node example.com as a subdomain of the com domain, and www is a label to create www.example.com, a subdomain of example.com. Each label may contain from 1 to 63 octets. The empty label is reserved for the root node and when fully qualified is expressed as the empty label terminated by a dot. The full domain name may not exceed a total length of 253 ASCII characters in its textual representation.[6] Thus, when using a single character per label, the limit is 127 levels: 127 characters plus 126 dots have a total length of 253. In practice, some domain registries may have shorter limits.

Almost all the services offer some sort of page builder that makes it easy to drag and drop to build your page. These are great for getting started, but they often lock you into the service. Most page builders are proprietary to the service, or don't create HTML that's portable enough to be easily moved to another service if you decide it's necessary.
Used 000webhost back in ye olde days. Back then it was the only legit free host, and others were data scams, or so it seemed anyway, because the computer antivirus (old Avast) could go into a meltdown once you visited their websites. Looks like the times have changed – but I’d keep tenacious about my personal data around most of these companies. If they don’t make money with hosting, it’s anyone’s guess how they make that money..:)
The company got bonus points for its policy of performing regular daily backups, even on the lowest-priced shared hosting accounts. It lost points because its promotional price on the low-cost shared hosting does go up after the promotional period. That said, Bluehost also gained points for offering 24-7 phone support and SSH access for certain plans.

We use only the latest, fastest web servers available from Dell, HP and Supermicro. Every one of our servers has at least two processors, 16GB of RAM and four hard drives with RAID protection. We place a lighter load on our machines than the other guys do, so your site has breathing room during busy periods and you can run more complex scripts. And we use CloudLinux to optimize.
The company also offers higher-end Windows and Linux servers, available with Plesk and cPanel respectively. We were very intrigued to see that the company offers low-end Atom-based dedicated servers as well as the more traditional Xeon-based machines. One great resource for those doing some basic experimentation, or site development, is that they have a free, three-month trial for one of their lightly-equipped Atom servers.
Yet if you are looking for a good quality web hosting service for a solid website or something to learn and grow with, you’d be much better off choosing a proper paid web hosting service. Best web hosting providers are perfect tools for actual professionals. However, free web hosting still has a lot of great uses. One of them is helping people to learn.
Domain names are often seen in analogy to real estate in that domain names are foundations on which a website can be built, and the highest quality domain names, like sought-after real estate, tend to carry significant value, usually due to their online brand-building potential, use in advertising, search engine optimization, and many other criteria.
A fictitious domain name is a domain name used in a work of fiction or popular culture to refer to a domain that does not actually exist, often with invalid or unofficial top-level domains such as ".web", a usage exactly analogous to the dummy 555 telephone number prefix used in film and other media. The canonical fictitious domain name is "example.com", specifically set aside by IANA in RFC 2606 for such use, along with the .example TLD.
Many web hosts offer limited features in their starter packages and then expand the offerings (sometimes tremendously) for higher-tier plans. Read the small print to make sure the plan you are selecting offers what you need. If you need a site builder application to design your website, make sure that the low-cost web host you are picking actually comes with a site builder. Many of them require you to pay for the builder as a separate add-on. Website builders usually don't cost a lot of money, but if you can find a web host that includes one for free, that's money in your pocket. And, if it's integrated with your hosting service, you're more likely to have a smooth, supported experience.

Dedicated hosting is not for everyone and generally provides more resources than the average business requires. Dedicated hosting is ideal for very large companies that regularly experience a high volume of internet traffic or sales, or require a large amount of disk space. Dedicated hosting grants you the greatest flexibility, customization, and security of the three types of hosting but is also the most expensive.
When a website has been secured with an SSL certificate, a visitor will see a padlock icon in their web browser and they’ll be connected to the site using the https:// protocol. With the SSL certificate in place and the user accessing the site through https, the connection between the browser and the web server has been secured and sensitive information can safely be transferred.
The host may also provide an interface or control panel for managing the Web server and installing scripts, as well as other modules and service applications like e-mail. A web server that does not use a control panel for managing the hosting account, is often referred to as a "headless" server. Some hosts specialize in certain software or services (e.g. e-commerce, blogs, etc.).
