3. Web Hosting:

A web hosting service is a type of Internet hosting service that allows individuals and organizations to make their own website accessible via the World Wide Web. Web hosts are companies that provide space on a server they own or lease for use by their clients as well as providing Internet connectivity, typically in a data center.

Many large companies who are not internet service providers also need a computer permanently connected to the web so they can send email, files, etc. to other sites. They may also use the computer as a website host so they can provide details of their goods and services to anyone interested. Additionally these people may decide to place online orders.

There are multiple hosting services available. Mainly among are-

Free web hosting service: offered by different companies with limited services, sometimes supported by advertisements, and often limited when compared to pay hosting.

Shared web hosting service: one's website is placed on the same server as many other sites, ranging from a few to hundreds or thousands. Typically, all domains may share a common pool of server resources, such as RAM and the CPU. The features available with this type of service can be quite extensive. A shared website may be hosted with a reseller.

Reseller web hosting: allows clients to become web hosts themselves. Resellers could function, for individual domains, under any combination of these listed types of hosting, depending on who they are affiliated with as a provider. Resellers' accounts may vary tremendously in size: they may have their own virtual dedicated server to a collocated server. Many resellers provide a nearly identical service to their provider's shared hosting plan and provide the technical support themselves.

Virtual Dedicated Server: also known as a Virtual Private Server (VPS) divides server resources into virtual servers, where resources can be allocated in a way that does not directly reflect the underlying hardware. VPS will often be allocated resources based on a one server to many VPSs relationship, however virtualization may be done for a number of reasons, including the ability to move a VPS container between servers. The users may have root access to their own virtual space. Customers are sometimes responsible for patching and maintaining the server.

Dedicated hosting service: the user gets his or her own Web server and gains full control over it (root access for Linux/administrator access for Windows); however, the user typically does not own the server. Another type of dedicated hosting is Self-Managed or Unmanaged. This is usually the least expensive for dedicated plans. The user has full administrative access to the box, which means the client is responsible for the security and maintenance of his own dedicated box.

  Managed hosting service: the user gets his or her own Web server but is not allowed full control over it (root access          for Linux/administrator access for Windows); however, they are allowed to manage their data via FTP or other remote          management tools. The user is disallowed full control so that the provider can guarantee quality of service by not allowing   the user to modify the server or potentially create configuration problems. The user typically does not own the server. The server is leased to the client...
