Web hosting is the business practice of providing space and bandwidth on a high-powered computer server that is connected to the Internet at very high speeds. Hosting companies maintain large networks of high-powered web server computers in a physical location known as a data center. These computer servers are connected to a very fast, and generally redundant, Internet connection. The data centers have primary and backup power, a fast connection to the Internet, and a security monitoring staff.
The web hosting companies provide a share of disk space and available bandwidth to a customer for a monthly fee. Once the customer is signed up, they can upload files to their personal space on the web server and the information is then viewable to anyone interested on the Internet. The monthly fee the web hosting company charges is much less than what it would cost to run a server out of your own home or data center. This is the reason these companies exist. They take care of all the hardware, software, and other technical needs for you.
Types of web hosting
There are many different types of web hosting offers, but the main three are shared, reseller, and dedicated. Each type of hosting is for a different purpose.
Shared Web Hosting
Shared web hosting is the most popular form of hosting. Shared hosting is a portion of disk space and bandwidth provided to you by the web hosting company on a high-powered server. There are many other web sites hosted on this server, and the hosting company is likely to have quite a few of these servers in a large data center. The resources of the server are shared by as many other websites as are allocated to that computer.
