By definition, a domain name is simply a human readable form of an IP address. In function it is the destination that you type into a web browser in order to visit a website, such a www.google.com. Metaphorically, it is very similar to how you would scroll to a contact in your cell phone rather than manually dialing the person by entering their full phone number; the phone number would be an IP address and the saved contact would be a domain name. Always buy a domain with a reputable domain registrar.
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.
It's important to note, however, that not all shared hosting is created equal. Different companies use different servers, each configured with different amounts of resources, and with different features. Furthermore, some companies host more websites on a single server than its peers. As such, that $10 per month shared hosting plan probably has many benefits over one costing $0.99 per month.
People often think that a web host is the main cause of a slow website but, this is often not the case. When picking a provider, it's important for find a hosting provider that is close to your users and has a good amount of RAM and fast CPU power. Beyond that, it's often the way the website is set up that slows it down for users. To ensure that your website speed is optimal for users you need to make sure you pay attention to the following:
WhoIsHostingThis aims to be the ultimate resource for choosing a hosting company that fits your needs. Find your perfect web host by narrowing down your choices with our comparison tool, selecting the hosting features that are most important to you. Be sure read our in-depth, unbiased reviews by our hosting experts, as well as real user reviews (by folks like you).
In result, your personal info, such as  physical address, emails, telephone number, etc is hide from the public. Domain privacy is important because your domain record (ie. the WhoIs data) may also be used in ways that aren’t legitimate or desirable. Since anyone can look up a WhoIs record, spammers, hackers, identity thieves and stalkers may access your personal information!

If you cancel within 30 days and your plan includes a free domain, Bluehost will deduct a non-refundable domain fee of 15.99 from your refund. This not only covers our costs, but ensures that you won't lose your domain name. You may transfer it to another registrar or simply point it elsewhere at your convenience. Please note newly registered domains cannot be transferred to another registrar during the first 60 days of the registration period. You retain ownership of your domain until the end of its registration period unless you renew it.

In order to register any domain, you must provide certain personal information that you may not wish to be publically searchable in the Whois database. Signing up for WhoisGuard is a great way to keep your registration data private. WhoisGuard acts as a "shield" for your searchable information, displaying the address, phone number, and email of the domain registrar (Namecheap, e.g.) instead of your own. Keep in mind that WhoisGuard is an optional security add-on that must be renewed separately when you renew your domain.
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.
Technical contact. The technical contact manages the name servers of a domain name. The functions of a technical contact include assuring conformance of the configurations of the domain name with the requirements of the domain registry, maintaining the domain zone records, and providing continuous functionality of the name servers (that leads to the accessibility of the domain name).
Free website hosting. A more advanced and “serious” solution. While using such services, you won’t be limited as much as by using website builders. You are able to select a content management system of your choice (i.e. WordPress, Joomla, Drupal, etc.) and use the allowed resources to build your website. Examples of such services are 000webhost, Awardspace – and a few of others listed below.
The availability of a website is measured by the percentage of a year in which the website is publicly accessible and reachable via the Internet. This is different from measuring the uptime of a system. Uptime refers to the system itself being online. Uptime does not take into account being able to reach it as in the event of a network outage.[citation needed] A hosting provider's Service Level Agreement (SLA) may include a certain amount of scheduled downtime per year in order to perform maintenance on the systems. This scheduled downtime is often excluded from the SLA timeframe, and needs to be subtracted from the Total Time when availability is calculated. Depending on the wording of an SLA, if the availability of a system drops below that in the signed SLA, a hosting provider often will provide a partial refund for time lost. How downtime is determined changes from provider to provider, therefore reading the SLA is imperative.[11] Not all providers release uptime statistics.[12] Most hosting providers will guarantee at least 99.9% uptime which will allow for 43m of downtime per month, or 8h 45m of downtime per year.
If you're not sure of the type of hosting your business needs, you might want to start small, with shared Web hosting. You can always graduate to a more robust, feature-rich package of, say, VPS hosting or even dedicated hosting in the future. Unfortunately, some hosts don't offer all hosting types. Consider how much you expect to grow your website, and how soon, before you commit to anything longer than a one-year plan. It's worth spending the time up front to make sure that the host you select with is able to provide the growth you envision for your site, as switching web hosting providers midstream is not a trivial undertaking.
With a shared hosting plan, you are renting space on a server that you share with other website owners. This also means you're sharing resources like bandwidth, memory, and processing power. This can be a problem, because a web host company typically supports hundreds, even thousands, of websites on a single server. Most of these websites will get very little traffic, allowing those who do see higher levels of traffic to use the resources they need. Nevertheless, there are no guarantees that you will get the resources necessary to support your website.
Once you decide you price range, you need to consider how long you'll need web hosting. If it's a short-term project—say, less than a month or two—you can typically receive a refund should you cancel your hosting within 60 days. Some companies offer 30-day money-back guarantees, others offer 90-day money-back guarantees. Once again, it's beneficial to do your homework.

A customer needs to evaluate the requirements of the application to choose what kind of hosting to use. Such considerations include database server software, scripting software, and operating system. Most hosting providers provide Linux-based web hosting which offers a wide range of different software. A typical configuration for a Linux server is the LAMP platform: Linux, Apache, MySQL, and PHP/Perl/Python. The web hosting client may want to have other services, such as email for their business domain, databases or multimedia services. A customer may also choose Windows as the hosting platform. The customer still can choose from Perl, PHP, Python and Ruby but may also use ASP .Net or Classic ASP. Web hosting packages often include a Web Content Management System, so the end-user does not have to worry about the more technical aspects.

You could think of the sites that share your server as your roommates; there's really not that much separating you from them. Sure, you can close the bedroom door, but they can still cause nightmares for you in the kitchen and the bathroom. In web hosting terms, all the sites share a single server's resources, so huge traffic spike on Site A may impact the neighboring sites' performances. It's even possible that another site could take down the shared server altogether, if it crashed hard enough.
