The user gets his or her own Web server and gains full control over it (user has root access for Linux/administrator access for Windows); however, the user typically does not own the server. One type of dedicated hosting is self-managed or unmanaged. This is usually the least expensive for dedicated plans. The user has full administrative access to the server, which means the client is responsible for the security and maintenance of his own dedicated server.
Having multiple servers hosting the same content for better resource utilization. Clustered servers are a perfect solution for high-availability dedicated hosting, or creating a scalable web hosting solution. A cluster may separate web serving from database hosting capability. (Usually web hosts use clustered hosting for their shared hosting plans, as there are multiple benefits to the mass managing of clients).[9]

Domain names are often simply referred to as domains and domain name registrants are frequently referred to as domain owners, although domain name registration with a registrar does not confer any legal ownership of the domain name, only an exclusive right of use for a particular duration of time. The use of domain names in commerce may subject them to trademark law.

A web hosting service is a type of Internet hosting service that allows individuals and organizations to make their website accessible via the World Wide Web. Web hosts are companies that provide space on a server owned or leased for use by clients, as well as providing Internet connectivity, typically in a data center. Web hosts can also provide data center space and connectivity to the Internet for other servers located in their data center, called colocation, also known as Housing in Latin America or France.
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.
BigCommerce is a bit different from our other hosting plans in that it's a SaaS (software-as-a-service) provider instead of an IaaS (infrastructure-as-a-service) provider. In other words, rather than renting space on a virtual machine where you setup and configure your own site, BigCommerce provides you with an app you login to that creates and online store. 
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.

To host a website on the internet, an individual or company would need their own computer or server.[7] As not all companies had the budget or expertise to do this, web hosting services began to offer to host users' websites on their own servers, without the client needing to own the necessary infrastructure required to operate the website. The owners of the websites, also called webmasters, would be able to create a website that would be hosted on the web hosting service's server and published to the web by the web hosting service.

In the first quarter of 2015, 294 million domain names had been registered.[17] A large fraction of them are in the com TLD, which as of December 21, 2014, had 115.6 million domain names,[18] including 11.9 million online business and e-commerce sites, 4.3 million entertainment sites, 3.1 million finance related sites, and 1.8 million sports sites.[19] As of July 2012 the com TLD had more registrations than all of the ccTLDs combined.[20]
The practice of using a simple memorable abstraction of a host's numerical address on a computer network dates back to the ARPANET era, before the advent of today's commercial Internet. In the early network, each computer on the network retrieved the hosts file (host.txt) from a computer at SRI (now SRI International),[4][5] which mapped computer hostnames to numerical addresses. The rapid growth of the network made it impossible to maintain a centrally organized hostname registry and in 1983 the Domain Name System was introduced on the ARPANET and published by the Internet Engineering Task Force as RFC 882 and RFC 883.

Intercapping is often used to emphasize the meaning of a domain name, because DNS names are not case-sensitive. Some names may be misinterpreted in certain uses of capitalization. For example: Who Represents, a database of artists and agents, chose whorepresents.com[23], which can be misread. In such situations, the proper meaning may be clarified by placement of hyphens when registering a domain name. For instance, Experts Exchange, a programmers' discussion site, used expertsexchange.com, but changed its domain name to experts-exchange.com.[24]
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).
17. SiteGroundThe competitive edge of SiteGround is its expertise in all types of Linux-tailored web hosting, as the company offers great plans for cloud, share, reseller, and dedicated hosting buyers. Carefully tailored enterprise hosting plans will also be available to corporate users, made flexible so that they could meet their specific needs and expectations. A reason why experts often recommend SiteGround are security precautions, as it provides a number of safeguarding measures, including the add-on HackAlert Monitoring ($1/month), the antispam software tools SpamAssassin and SpamExperts, IP address blocklists, and hotlink protection. At the moment, SiteGround hosts over 350,000 sites worldwide. You may also be interested to know that it supports ecommerce applications like Magento, osCommerce, and Prestashop. 
Complete Internet Solutions is not like that. The price they quote is your locked-in price. In addition, they offer a free twelve months on top of your term. So, if you sign up for two years at $3.95 a month, you pay $94.80 for the two years, and then pay nothing for another year. If you choose to renew at the end of those three years, you can repeat that pricing program without a fee increase. This is how it should be done.
Until 1991, the Internet was restricted to use only "...for research and education in the sciences and engineering..."[1][2] and was used for email, telnet, FTP and USENET traffic—but only a tiny number of web pages. The World Wide Web protocols had only just been written[3][4] and not until the end of 1993 would there be a graphical web browser for Mac or Windows computers.[5] Even after there was some opening up of internet access, the situation was confused until 1995.[6]
Beyond that, DreamHost is a top website hosting company for many reasons. It operate its own control panel, which is convenient and easy to understand. While phone customer support isn't available 24/7, it is responsive to live chat and tickets. The company uses super-fast SSDs for all its storage, has a free SSL certificate (for more secured web browsing) and provides SSH access for those plans that are intended for more technical users.
The web hosting provider got bonus points for its policy of performing regular daily backups, even on the lowest-priced shared hosting accounts. Be aware, though, that the promotional price on the low-cost shared hosting does go up after the promotional period. That said, Bluehost offers 24/7 phone support, a 30-day money-back guarantee and SSH access for certain plan options.
