Domain Registration
A domain name is a unique space or zone, that can be used to set up services on the Internet. Domain names are registered with a registrar, who then does the job of maintaining it with the top-level registry for that type of domain (for example, Verisign for .com, CIRA for .ca, etc..).
While computers locate spots on the Internet by IP address, these can be very difficult for a human being to remember. Through the use of DNS (the Domain Name System), a hostname based on a domain (such as www.exampledomain.com) can be a static name that resolves to a numeric IP.
DNS Service
DNS (Domain Name System) is the hierarchical system designed to translate human-readable information (such as a domain name, website, or other Internet-based resources) into the actual addressing protocols used by computers to navigate and locate information on the internet.
This sounds complex and can be at times, but the basics of it are actually very simple.
Computers route information and find things on the Internet using IP addresses (IP stands for Internet Protocol). Everything connected directly to the Internet has a unique IP address, which is reached through the interconnected routers, peers, bridges, and data pipes that make up the backbone of the Internet. Very few people can remember 205.210.42.30, for example, and since these change sometimes, an easy-to-use human-understandable name, such as www.easydns.com is necessary.
What DNS does is provide a system to track what IP address that name will resolve to, and answer back quickly and authoritatively so a browser can get the website with no noticeable interruption.

Web-Hosting
A web-hosting service is required when a website for a domain is needed, but can also be used for hosting files, images, games and similar content. 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-hosting providers typically offer three main types of hosting:
