Different Types of Web Hosting

You will find many different types of web hosting companies. Choosing a web hosting provider depends on what type of website you have. The main website hosting types are: shared, free, managed dedicated and unmanaged dedicated web hosting. Free web hosting services place ads on web pages and can cumbersome and annoying for visitors. The other web hosting types usually offer great support and bandwidth but charge a monthly fee.
Shared Web Hosting
Shared webhosting is the most widely used web hosting service. Shared website hosting permits more than one site to be hosted on the same server. Here, the web hosts provide system administration. Most web hosts provide the user with features such as ASP, PHP, MySQL, large bandwidth, and multiple e-mail addresses. There are many other services available in shared web hosting, including the ability to have your own domain name. Shared web hosting is furthermore a way for the hosting business to offer affordable web hosting to their clients when more server users equals less expenses and server maintainance
Free Web Hosting
Free web hosting is the simplest kind of webhosting service. Ads on hosted web sites generally support this type of website hosting. We have not found any free webhosting that we could recommend. Most of them are of low quality. They do not provide the user with MySQL, multiple e-mail accounts or the ability to run any scripting language. The type of domain one receives in free web hosting is typically a sub-domain (yoursite.webhost.com) or a directory (www.webhost.com/~yoursite). Our recommendation is to avoid these kinds of web host services. Choose a cheap web host instead.
Dedicated Web Hosting
Dedicated hosting is a good option for someone who wants more storage and bandwidth, and also wants certain characteristics that are not available with shared web hosting. Here the user is not limited to a certain number of databases and e-mail addresses, and also gets a very large amount of bandwidth. Generally a dedicated server plan offers the user with a monthly bandwidth of 500 GB to 1 TB. In unmanaged dedicated web hosting, the user is the server administrator, permitting the user the greatest amount of control and flexibility. You need a lot more knowledge if you want an unmanaged server because it is not easy to be a server administrator. The function of the website usually determines the type of web host. Features, support, reliability, and security decide the pricing of webhosting providers.
