A good comparison of using a virtual private server is the process of owning a condo. You share the property with a few others but have ownership of your own space. Medium sized or growing companies who desire a bandwidth upgrade are perfect VPS users. For a moderate cost increase, they have a more customizable, reliable and secure system than they would have with shared hosting.
Domain names are organized in subordinate levels (subdomains) of the DNS root domain, which is nameless. The first-level set of domain names are the top-level domains (TLDs), including the generic top-level domains (gTLDs), such as the prominent domains com, info, net, edu, and org, and the country code top-level domains (ccTLDs). Below these top-level domains in the DNS hierarchy are the second-level and third-level domain names that are typically open for reservation by end-users who wish to connect local area networks to the Internet, create other publicly accessible Internet resources or run web sites.
A fully qualified domain name (FQDN) is a domain name that is completely specified with all labels in the hierarchy of the DNS, having no parts omitted. Labels in the Domain Name System are case-insensitive, and may therefore be written in any desired capitalization method, but most commonly domain names are written in lowercase in technical contexts.
Dedicated servers are used to power complex applications and high-traffic websites. You might also opt for one if you serve a large quantity of media, such as high-resolution images, audio files, and streaming video clips, or you see very high levels of traffic (or perhaps both are applicable). Dedicated hosting also provides the highest level of security and server customization possible. Also see: Colocation.
I wanted to point out that you do not mention critical issues. One is that some of the Top 5 Hosting Services do not offer an e-mail account. Others charge $14.00 a year to transfer your a Domain Name and host it with them or else the domain owner does not get the hosting for free. The list of unpleasant conditions that render those top 5 Hosting Services substantially less appetizing than you painted the picture, and that list goes on and on.
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).
It is very rare for a customer to exceed normal usage while managing a website. Typically, customers only experience issues if they use their accounts for storage (for example large multimedia files) or file sharing. Our hosting services are not intended to support these activities, and in accordance with our Terms of Service your disk space and bandwidth usage must be integrated into the normal operation of a website. We offer various plans that better address high bandwidth and large storage requirements. Please contact us for details.
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.
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.
