What is Web Hosting?
Web Hosting is the service that’s provides space on the Internet for websites.
When you develop a website on a pc or laptop, you need to publish it to a web hosting service so that other people can see it.
Web hosting services work by providing high-powered computers (web servers) with a high-speed network for your website to live on. When someone types in your web address (such as www.midphase.com) they will be connected to your web server where they can surf and download the pages of your website.

Shared Web Hosting
Shared Web Hosting is the most common type of web hosting, and is also the easiest to start out on.
Shared Hosting is a service where one server is shared between many customers. This typically offers the following advantages and disadvantages:

It’s the most cost effective way to go if your on a tight budget. You don’t need to pay for the whole server upfront
It’s easier to use. The server is preconfigured with the most popular options and your hosting provider will take care of any maintenance and security updates for you

Because shared web hosting is the most common type of web hosting, most hosting companies simply refer to itas web hosting or web site hosting. Midphase shared web hosting comes in two flavors depending on your preferred operating system: linux web site hosting and windows hosting.
VPS
VPS stands for Virtual Private Servers, and is essentially a half-way house between shared hosting and dedicated hosting.
VPS customers still share the physical server hardware with other VPS customers, but special virtualization technology partitions the server so that each partition has its own dedicated resources and can be configured almost like a full dedicated server.
This typically offers the following advantages and disadvantages:

Dedicated Hosting
Dedicated server hosting is where customers have an entire server and all its resources dedicated to their personal use. Dedicated hosting typically offers the following advantages and disadvantages.

Flexiblility & customization – customers can choose the exact hardware and software specifications of the server to meet their needs.
Dedicated resources and guaranteed performance – customers don’t share their server resources with anyone else.
Full control – customers have full root access to their servers and can configure and tweak their setup to meet their needs.
Prior technical knowledge is required – unless a server management option has been selected it will be your responsibility to manage and configure the server.
More expensive – the cost of the server isn’t shared with any other customers.

Managed Hosting
Managed hosting gives customers all the benefits of a dedicated server without any of the server administration overheads.
Depending on the server management package chosen, the system administrators of your hosting company will perform a variety of server management tasks on your behalf.
These may include:

Rebooting your server
Keeping your operating system and or control panel up to date
Installing security patches
Monitoring the performance of your server
Installing 3rd party applications or configuring your server from scratch
