Web hosting is the process of putting your web site on a web server or web host, so everyone connected to the Internet can see it. If you have a permanent connection to the Internet you could host your web site on your own computer, but that is in general not a good idea. A good web host is a real server in a datacenter with a fast high bandwidth connection to the Internet. And, to make sure you can move your web site to another web host, if necessary, you need a web hosting provider that supports domain hosting.

Most Internet Service Providers (or ISP) will give you a free web site when they provide you with access to the Internet. They do this because they don't want to give you a permanent IP address, which is what you need if you'd like to host a web site on your own computer. Unfortunately, most ISPs don't support domain hosting with their free web sites. Hence, the URL of your web site is an extension of the URL of your ISP. So what happens when you change ISP? You will have to change the URL and nobody can find you anymore.

The use of a domain name for your web site is absolutely necessary for a professional web site, and to host your own domain you will need to find a real web hosting provider with domain hosting.

A subdomain is an extension of a domain name that normally points to a subdirectory of a web site. For example a subdomain for p2phosting.com would be hosting.p2phosting.com. The hosting part in front of p2phosting.com is the subdomain name.

A webmaster is someone who has the responsibility of managing a web site. Most web masters not only oversee the day to day running of the web site and its web hosting, but also develop new pages for the web site and optimise and promote the web site for the search engines. So, when you decide to design your own web site and start looking for a suitable web hosting provider, you have become a web master.

Bandwidth is a measure that reflects how much data can be transferred over a data communication channel.

In web hosting plans the allowed bandwidth generally indicates how much data can be downloaded from your web site per month, and therefore indicates how many web pages and pictures your visitors are allowed to download. If the average amount of page views per visitor is assumed constant, the allowable bandwidth restricts how many visitors you are allowed to have per month.

Just as important, however, is how fast the communication channel between your web host and the Internet is. The amount of data that can be transferred per second is also called the bandwidth of this channel, and this bandwidth is shared by all the web sites hosted by the same provider. If this bandwidth is insufficient, you'll sometimes notice a slow down in the display of your web pages. In most cases, however, such a slow down is more likely to be caused by an overload on the web server itself.

A web server is either a special computer or server for reliable hosting of web sites, or the software application that runs on that server. The two main web server applications used by most web hosting providers are
Microsoft's Internet Information Services (IIS) for windows hosting and Apache for Unix hosting. Both use the HyperText Transfer Protocol (HTTP) to transfer web pages to your web browser.

A dynamic web page is a web page that uses some scripting language, such as PHP or ASP, to allow the web server to adapt the content of the web page to a particular situation. Dynamic web pages can also be used to upload information from the browser to store it on the web server. Examples of web based applications that use dynamic web pages are guest books, chat rooms, web logs, and forums.

The information content that is displayed on the web page in your browser, will normally not be stored in the file containing that web page on the web server, but in a separate database. When the page is requested from the server, the web server will retrieve such a dynamic web page, process it to retrieve the relevant information from the database, and then puts that information in the HTML of the web page.

With dynamic web pages, the same information can be displayed on many different web pages, but only needs to be managed in one place: in the database. At the same time, we can create another web page to manage the information in the database (change it, update it, etc), as well as upload new information to enable users to create new web pages on the fly.

A static web page is a normal web page that is written in HTML and therefore needs no pre-processing on the web server. They are called static web pages to differentiate them from dynamic web pages. Static web pages can still contain Javascript, Flash, Shockwave, Java, and other non-html code to be executed in the web browser or in web browser plug-ins.

A web robot is a program that automatically retrieves web pages by following the links on web pages that it has already retrieved before. Web robots are used by search engines to find web pages for inclusion in their search database. Other web robots, however, will try to harvest any email addresses on your web pages to include in their email database, which they then use or sell to email spammers.

Through a special file on your web host, called robots.text, you can tell a web robot which pages you would like it to ignore. Most email harvesting robots will, of course, just ignore the instructions in your robots.txt file.
