When we visit a website, our internet browser displays a web page that is downloaded from a web server. Website is a collection of many web pages and to allow the visitors to view these pages on the internet we need to place them on a web server. Web servers are powerful computers with large hard drives and owners of web server offer the space of their server’s hard drive on rent. Now web hosting is a service which gives us a space to place our website on a web server so that people can view our website on the internet.A web server gives us an opportunity to own web space on rent. They will give us storage place (up to some limits) and bandwidth for what we will pay them certain amount of money as a rent. Web hosting provider gives us many plans that include different web space and bandwidth depending on the plan we want to buy from them. The more we will pay, the more web space and bandwidth will be given in return.A large web space provider can host thousands of websites on their server. Larger companies have more powerful and multiple servers that can entertain a lot of websites at same time. All these web servers are connected to internet with high speed internet connection and they remain connected 24/7 throughout the year. These companies develop extensive power backup system, HVAC to control the temperature, virus detection, and disaster recovery and data backup facility to provide excellent service to their clients.Types of Web Hosting:Hosting can be divided in to many types depending on the resources and nature of the facilities you want in your package plan.
