1. To have Web site Hosted
on the Internet
To have a Web site on the Internet you first need to have a
Web server. Unfortunately, owning a Web server can be very costly
and requires technical expertise that most businesses don't have. This
is where Web Hosts come in. Web hosting companies provide the equipment
and other technical resources that you need without the headaches that
come when you have to do it yourself.
Think of a Web Host as the landlord of building. A landlord
rents out storefronts to various businesses. Each business decorates and
runs their store differently, and doesn't worry about the maintenance of
the building. In a similar way a Web Host rents out space on a Web
server, (or entire Web servers), to various businesses. Each business
builds their own Web site and never has to worry about the maintenance
of their Web server.
In other words, the Web Host provides the place on the
Internet where your Web site lives. It's a lot cheaper than buying you
own server, and you don't have to hire the technical staff to take care
of it.

2. What is a Shared Server
Shared servers offer clients the ability to host their
Web site on a powerful, professionally managed server, at a low
monthly cost. Shared servers provide individual Web sites with
redundant connectivity, 99 percent uptime and 24/7 monitoring for a
fraction of the cost of a dedicated server.
Intended Clients and Uses
Shared servers are an excellent solution for entry-level hosting
needs. Designed to host small scale e-commerce sites and static Web
pages, shared servers offer first-time Webmasters a reliable Web
presence without advanced technical skills.
Server Response Time
The activity of other sites and the number of other sites on the
server can affect shared server performance.
Flexibility and Scalability
As you are restricted to the server box space, upgrade capacity is
primarily focused on disk size and throughput.
Software
Shared Servers are limited to the software that is installed by
hosting provider.
No technical skills required
to use a shared server.
Shared server hosting provides a cost-effective way for
entry-level Webmasters to maintain a reliable Web presence without
extensive technical resources.

3. Virtual Private (VPS) Server
Virtual Private Servers (VPS) combine the flexibility of
a dedicated server with the economical prices of shared server
hosting. VPS Web sites reside in private and protected areas on a
shared server and maintain an independent set of applications,
allowing the client to share the expenses of hardware and network
connections while maintaining a secure allocation of RAM and CPU.
Intended Clients and Uses
Virtual Private Servers are intended to meet entry- to mid-level
hosting needs. The potential functions of a VPS are wide and varied.
It can be used as a simple FrontPage¬ server or as an advanced,
database-driven commerce server.
Server Response Time
Virtual environments are not affected by the activity of other sites
on the server, but their allocated resources limit site performance.
Flexibility and Scalability
Upgrade capacity is primarily focused on disk size, number of
processors and throughput.
Software
As you maintain your private section of the server, you are able to
incorporate many software options.
Virtual Private Servers provide customers with an
independent set of Web applications to handle more advanced Web-based
applications, without the costs associated with a dedicated server.
Moderate technical skill level is required. UNIX administration, basic
programming, and database capabilities are needed to operate a VPS.

4.
Dedicated Server
Dedicated servers are a single computer fully devoted to
the needs of one customer. They allow for faster access to information
and provide the customer with greater flexibility to add advanced
database and e-commerce applications. As the customer does not share
RAM, disk space or a connection to the router, dedicated servers
provide customers with the most advanced Web hosting solutions.
Intended Clients and Uses
Dedicated servers are designed for mid to advanced-level hosting
needs such as "mission critical" and high-traffic sites. The servers
can handle heavy data-driven sites, advanced e-commerce programs,
video streaming, and multimedia programs.
Server Response Time
Dedicated server response time depends solely on the volume of
activity on the customer's Web site.
Flexibility and Scalability
All aspects of the platform (disk space, memory, etc.) are
upgradeable since dedicated servers are single client machines.
Software
Unlimited ability to download software programs to your server.
Dedicated servers provide high levels of security,
connectivity and scalability, to support high volume and mission
critical Web-based applications. Advanced technical knowledge is
recommended-experienced programming and database capabilities.
