The term colocation is used in the computer industry to describe the use of a specialist data centre that is run independently and hosts file servers for a number of different companies.

Independent data centres of this type are also called colocation centres, 'colos' for short, or the more descriptive 'carrier hotels'. These data centres are set up by specialist firms with expertise in information technology, to serve the needs of numerous clients. That way, the clients can simply outsource this service to a colocation supplier and let them take care of everything for them. This is much more sensible that trying to do it yourself, for a number of reasons.

Cost is an important consideration. If you were to invest in a state of the art data infrastructure yourself, you would have to spend more than a specialist supplier who could broker wholesale deals for IT services on your behalf which could save you a great deal of money in the long run.

Economies of scale come into play too. A professional colocation supplier will have invested in large, industrial-strength systems which are bigger and more powerful that any individual firm would ever need. This means that you are getting the benefit of a more powerful system, and you can buy in to it for a low relative cost.

Time is another element of the equation. Why re-invent the wheel yourself, when a colocation supplier has data solutions at their fingertips. These would include solutions to your immediate requirements, and also remedies to any future IT problems that you don't even know you have yet!

Access to expertise is a further advantage of using colocation.
You will have the benefit of advice and support from experts in the field who have experience of looking after many different types of requirement across numerous different industries. And this access will usually be arranged on a shift system, so that you can always speak to someone at any time of the day or night on any day of the week, including weekends and public holidays like Christmas and New Year's Day.

In addition to gaining access to IT systems for networks, servers and data storage, colocation firms will also give clients the ability to interconnect with numerous telecommunications suppliers and providers of other network services. Because colocation firms look after many kinds of IT need across a wide range of industrial sectors, they will be able to suggest packages of services after doing a survey of your particular needs and current situation.

And because the colocation firm is an expert in their field, that means that the package they propose for you will have the capability of being adapted as the needs of your business change. Upgrades can be discussed and arranged quickly with people you trust, who know your business. This means that clients can then focus on their core business, without having to divert from what they do best and try and become a mini-expert on IT data systems themselves.

So you want to build a website and at this point you may be very excited. There seems to be so much opportunity online that it seems that you cannot go wrong. You read all those sales pages out there telling you that you only need work fifteen minutes a day and you will make thousands.

Forgive me I am being a little dramatic but I think you get the picture.

The solid fundament when it comes to building websites is to understand why people go online. Number one they go online for information. This information can be entertaining or solution orientated. It can also be sought out for research purposes.

So the first question is which category do you fall into? Now let me give you that tip. If you are interested in a subject lets take health as an example its imperative at the outset to have an open mind.

What you think may work, may not so you have to be prepared for that. Secondly you need to make sure and research thoroughly so that when you make the decision you can at least know that you have done your homework and therefore your odds of success are far greater.

Let me tell you what happened to me. I went out bull headed and just picked a topic that I was interested in and was not adaptable at all. Then I just built a site and put a lot of work into it but got very little results. Then of course I lost motivation and before you know it I almost got burnt out.

I cannot tell you how depressing it is when your dream of working online becomes a nightmare of failure.

To conclude keep it simple, be adaptable, focus heavily on research and understand that it takes work so don't be easily influenced by all sorts of hype that will in essence only distract you.

What is PHP?

PHP stands for PHP: HyperText Preprocessor, it is a server-side scripting language, and as the name goes, it is to create dynamic and interactive Websites for your visitors. Maybe you currently make your Websites in HTML? HTML alone cannot create dynamic Web pages, HTML is clearly defined as a static language, as it is always static and mainly is used for structuring (or styling, in some cases) a document (or a Web page, if you like).

What do we mean by server-side scripting?

You may already know, but HTML is a client-side language, so the browser translates the HTML code into "bytecode" that the computer can understand, and so the computer translates bytecode into what we can clearly understand, text, for example. Server-side scripting is a little different, a little bit more added to the story. As with PHP, server-side scripting languages have an interpreter inside a machine, that translates the code (in our case, PHP code) to HTML code (that the browser can understand), and then the same process will take place with the browser translating the HTML code to bytecode, and so forth. With server-side scripting languages, you don't need anything adding to your browser or computer, as the interpreter inside the machine that hosts the particular Website does most of the work.

What's the fuss with server-side scripting languages, then?

The thing that makes server-side scripting a must nowadays is because it can generate dynamic Web pages, but what do we mean by dynamic Web pages? Well, imagine you wanted to start a forum, and you used HTML. Okay, you used a form to submit the data and it is sent to your e-mail address, and you have to edit the static Web page every time you want a new post added. That, to me, would be the most annoying job of creating a Website. However, with PHP (or any other server-side scripting language, for that matter), can be completely automated, and you'd not have to edit your file even once! The thing that PHP does, is sends the form data to a different page, saves it in "pre-defined" variables (things that store a value), and using something called a "while loop" that continually loops all the posts saved in the Web page - and that's it! PHP stores the posts in a MySQL database (something that holds data, if you like, like member accounts, etc) and uses that as long-term memory.

But if we're talking about server-side scripting languages, what makes PHP different from the rest? Well, simply put, PHP is probably the best thing that has come into the server-side scripting genre. If you have heard about other scripting languages like Perl or ASP/ASP.NET, you'll come to find that they are extremely hard to learn from. Put it this way, the majority of Web developers that use ASP.NET, for example, are those who have come from a different programming background, like have known VBScript, or other languages that's in relation to ASP.NET, the same with Perl. The difference between PHP and the rest, is PHP is incredibly easy to learn, especially for the newbies towards this industry, and PHP has took several steps to ensure an easy introduction to those newbies to the world of programming. Let's do an example, lets see which is the easiest to understand, out of PHP, VBScript and Perl, by doing a simple "Hello World" program, that outputs text to a Web page:

PHP:

echo "This is some text that'll be shown in a Web page...";

VBScript/ASP.NET:

Response.Write("This is some text that'll be shown in a Web page...");

Perl:

#!/usr/bin/perl

print "content-type: text/html nn";

print "This is some text that'll be shown in a Web page...";

Okay, now I am not going to say things like "well, obviously PHP is the easiest to understand" - as obviously, we all have different preferences, but what I can say is, that they all do the same thing. Which seems the most logical to you? In my opinion, the two most logical ones for me is PHP and VBScript/(ASP.NET).

Now it's up to you which one you want to go ahead with, experiment which one is best for you, after all, we all have dfferent tastes.

Good luck!
