Do you know web hosting??? It’s a business of providing the storage, connectivity, and services necessary to serve files for a website. A company that provides web hosting services is called a web host, and their detailed offers of storage, connectivity, and services are called webhosting plans. There are literally thousands of web hosting services, ranging from individuals to worldwide corporations, and many web hosts offer multiple web hosting plans.
A number of hosting companies describe their services as virtual hosting. Virtual hosting usually implies that their services will be transparent and that each Web site will have its own domain name and set of e-mail addresses. In most usages, hosting and virtual hosting are synonyms. Some hosting companies let you have your own virtual server, the appearance that you are controlling a server that is dedicated entirely to your site.
Dedicated hosting is the provision of a dedicated server machine that is dedicated to the traffic to your Web site. Only very busy sites require dedicated hosting. Many companies purchase their own servers and place them on a site that provides fast access to the Internet. This practice is called colocation.
The scope of hosting services varies widely. The most basic is web page and small-scale file hosting, where files can be uploaded via File Transfer Protocol (FTP) or a Web interface. The files are usually delivered to the Web “as is” or with little processing. Many Internet service providers (ISPs) offer this service free to their subscribers. People can also obtain Web page hosting from other, alternative service providers. Personal web site hosting is typically free, advertisement-sponsored, or cheap. Business web site hosting often has a higher expense.
Single page hosting is generally sufficient only for personal web pages. A complex site calls for a more comprehensive package that provides database support and application development platforms (e.g. PHP, Java, and Ruby on Rails, ColdFusion, and ASP.NET). These facilities allow the customers to write or install scripts for applications like forums and content management system. For e-commerce, SSL is also highly recommended.
