A domain name is basically part of a website address, just like the house number or apartment number of your home is essential to finding your home. A domain name is a name chosen by you that is entered into a computer, for example as part of a website or other URL, or an e-mail address. It is then looked up in the global Domain Name System (DNS) by your computer which informs the computer of the Internet Protocol (IP) addresses assigned to that name. The computer can then locate the online address that you are looking up in the browser window. Domain names are hostnames that provide more memorable names to stand in for numeric IP addresses. They allow for any service to move to a different location in the topology of the internet (or another internet), which would then have a different IP address.
By making possible the use of unique alphabetical addresses instead of numeric ones, domain names allow internet users to easily find and communicate with Web sites and other server based services. The flexibility of the domain name system allows multiple IP addresses to be assigned to a single domain name, or multiple domain names to be assigned to a single IP address. This means that one server may have multiple roles, such as hosting multiple independent Web sites, or one role can be spread among many servers. One IP address can even be assigned to several servers.
An internet hosting service is a service that runs internet servers, allowing organizations and individuals to serve content to the internet. There are various levels of service and various kinds of services offered. A common kind of hosting is web hosting. Most hosting providers offer a combined variety of services. Web hosting services also offer e-mail hosting service, for example. DNS hosting service is usually bundled with domain name registration.
A web hosting service is a type of internet hosting service that allows individuals and organizations to host their own website, and users with online systems for storing information, images, video, or other content accessible via the World Wide Web. Web hosts are companies that provide space on a server they own for use by their 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 servers they do not own.
