A web hosting service is such a kind of Internet hosting service which hosts sites for customers, i.e. it provides all the facilities needed for them to build and maintain a website and makes it available over the World Wide Web. Companies offering web hosting services are also known as web hosts. A web host provides a large variety of facilities such as data transfer, email, etc., for clients. The internet, in turn, is made available by these web hosts via a server.

There are many companies which provide web hosting services. They are known as hosts or web hosting companies. The common feature among all such companies is that they provide a service for clients to host their web pages on their servers. In this way, the web hosts help the clients in running their websites on a large number of servers placed at various places around the world.

In the past, before the emergence of web hosting companies, people would outsource to a web hosting company to run their websites. This was done so that the web master could concentrate on other important aspects of the site. However, this trend began to decline with the arrival of cheap hosting services. Now, most of the companies outsource to web hosting companies. However, the web hosting companies still maintain their own websites where people post their applications.

Basically, there are two kinds of hosting: shared hosting and dedicated hosting. Shared hosting provides many websites on a single server. On the other hand, dedicated hosting is not just about one server, but rather a server which is exclusively dedicated to a particular website only. There are many web hosts in the market. These hosts compete with each other to get business from clients and therefore they offer many different services at affordable prices.

These different types of hosting can be broadly classified into two types: first-party hosting and third-party hosting services. First-party hosting services include the use of the servers of different web hosts on a single network. They allow users of these services to experience fast loading of data and make it possible for different types of applications to function without any problems. The user of the service can control the settings of the software and therefore can choose what type of security measures he wants to have. However, since the users of this kind of service get the access to the control panel, it is very vulnerable to hackers who can gain access to the information stored on them.

On the other hand, third-party hosting services include the use of the resources of different web hosts on a single network. They allow users to use their own web servers and therefore provide the users with better control over the different types of applications they want to install on their web servers. While these Web hosting services offer the advantages of being cheap and easy to use, the downside of using them is that they are open to all types of attacks by hackers who can hijack the sites and cause havoc on the performance of the server.
