A shared web hosting service or virtual hosting service is a form of web hosting service where more than one instance of the same web server is hosted on a single physical server.
The hosting service must include system administration since it is shared by many users; this is a benefit for users who do not want to deal with it, but a hindrance to power users who want more control.
Shared web hosting can be accomplished in two ways: name-based and IP-based, although some control panels allow a mix of name-based and IP-based on the one server.
They will not work with browsers that do not send the hostname as part of requests. This is true for older HTTP/1.0 browsers that have not retrofitted the host field feature from the HTTP/1.1 protocol. (The "Host" header that distinguishes between various DNS names sharing a single IP address was optional in HTTP/1.0; it is mandatory in HTTP/1.1, issued in 1999 as RFC 2616.)
The differences between shared and dedicated hosting can range from cost, features and benefits to the level of technical knowledge required.

Basically, I need a webserver with enough bandwidth to serve the number of page requests I expect to receive. But, like most things in life, hosting is not quite that simple. Depending on project requirements, I may also need access to a scripting language, database, or data backup. Each of these additional capabilities will put a load on the server's processor, so I may have a minimum processor speed requirement, as well. But before I can really shop for a hosting service, I need to answer a bigger question. How much hosting power do I need? The most common choices are shared hosting and dedicated servers. I will limit todays discussion to these two choices.
Typical websites are well served by typical web configurations. However, not every project is typical. Sometimes the best solution is a custom web server configuration. Using .htaccess can often be used for a per-site configuration change. When it can't, I may be forced into a dedicated server so that I have total control over the server's configuration. If this is the route I take I need to decide whether I want the quickness and flexibility of configuring it myself, or the security of knowing I can fall back on the host's administration team for help
