It can be defined as “a place for your website or emails,” though this definition simplifies conceptually that web hosting is actually space on the Internet for virtually any type of information, whether files, systems, emails , videos etc.

Hosting can be divided into several types:
Free hosting: usually with limited capabilities. Running scripts (eg PHP) and the conduct of a private domain is often not possible. Disk space and bandwidth are usually limited. Sometimes adds the hosting company advertising to each page.
Shared hosting: Multiple (hundreds) of websites on the same server installed. This makes it possible for one site to the other makes slow down or even crash.
Reseller Hosting: for those who own a web host would be. Provides a high disk space and bandwidth that can be spread over all sites that the user wants to place. Compare to shared hosting, but the buyer has more freedom and can sell web hosting.
Virtual Private Server (VPS) hosting: allows a physical server multiple virtual servers housing. Each customer has administrator or root access to the server and configure user rights to. The customer can have a VPS for applications other than Web sites use. If a virtual server crashes, then the other customers will not notice. Processor capacity and bandwidth to the hard disk is divided by the customers.
Dedicated hosting: the customer gets really own server (machine). Well it has to observe data limit and hard disk space.
Managed hosting: the client receives a server (or a part of here) but gives the management and maintenance of this off your hands.
Co-located hosting, the customer places an own server in the space of the provider. It is required to have a “19″ rack mountable “server to place of 1, 2 or 4U (Units) 1U = 1.73 inch = 4.4 cm high. Again, the customer has to take into account data limit, but hard disks can be placed in desired quantity or replaced by larger.
Cloud hosting: a new form of hosting on clustered (interconnected) servers, creating a large scalability arises. The advantages are better availability, more reliable and higher speed.
