What Is Web Hosting?

If you’re new to buying web hosting or running a web site, this page could answer some of those nagging questions. We’ll take you from the very beginning and work up to some fairly advanced concepts – but don’t worry, everything on this page is suitable for absolute beginners.

What is web hosting?

Think about the files and folders on your computer. They are stored on the hard disk of your desktop or laptop computer, ready for you to access them whenever you like. A web page is a file, just like your word processing documents. Just as your word processing documents require your computer to store them, all web pages require a computer to store them.

The difference is that web pages are generally intended to be seen by the general public. To enable this, the computer on which they must be stored must be of a much higher specification than your desktop PC, and must be connected to the Internet through a very powerful link.

A computer on which web pages are stored is called a web server (because it serves pages, on request, to users on the Internet). Collectively a bunch of web pages is a web site, and collectively all the web pages in the world form the World Wide Web (WWW).

The job of making web sites and web pages available to many users is called web hosting. We sometimes like to call the product we offer web space, because we are selling “space” on the Internet for you to host your web site. Web space is measured in megabytes, in exactly the same way as the space on your own computer is measured.

Why do I need web hosting?

It is technically possible to connect your own PC or Mac to the Internet and have it serve pages. But it is not practical since usually a home-based Internet connection is not powerful enough to serve many users at the same time.

For this reason, web hosting companies exist. They own and maintain very powerful web servers which store your web pages. They connect these web servers to the Internet by very powerful connections, enabling many web users to access your web pages at the same time.

If you want to run a web site you need web hosting because unless you’ve got unlimited funds you would not be able to afford the web servers and connections necessary.

What else do web hosting companies do?

As well as providing web space, web hosting companies provide other “value-added” services. The extent of these varies from company to company but there are some key services provided by nearly all. These are the registration of domain names (see below) and provision of email. They may also provide technical support either through their web sites or by email or telephone.

Are there different kinds of web hosting?

Yes, of course! There are many different varieties of web hosting, designed to meet different needs. A two-page web site set up by an individual will need far less robust web hosting package than a multinational high-traffic site set up by a big company. There are a few key differentiating factors between the packages web hosting companies provide.

Amount of web space

This means how much web space the web hosting company will allow you to use for your web site. This can vary but usually starts at around the 100 megabytes mark, and can go all the way up to 1000 or 2000 megabytes. For all but the biggest web sites, 100MB is more than adequate. Some web hosting companies offer much more space – they are able to do this because they know that the average web site comes in at less than 100 megabytes.

Number of email addresses

This means how many email addresses the hosting company will permit you to have. For budget accounts, this is usually somewhere between 1 and 10 email addresses. Some higher-end packages permit say 250 addresses. Here at Dog’s Web Hosting we like to go one further, we offer unlimited email addresses on some of our packages.

Quick reference

    1 letter on a page = 1 byte
    1024 bytes = 1 kilobyte
    1024 kilobytes = 1 megabyte
    1024 megabytes = 1 gigabyte
    Bandwidth (or data transfer)

This is a much misunderstood measure, but it is really important if your web site starts to generate a lot of interest from web users. It means the amount of data your web site can transmit to web users. For example, if a web page in your web site is 10 kilobytes (about 1000 words on the page) in size, and one Internet user views it, you have used 10 kilobytes of bandwidth. If 10 users request that page you have used 100 kilobytes of bandwidth. Bandwidth is normally measured monthly.

Most small web sites will need under half a gigabyte of bandwidth per month. That means you can serve about 52,000 web pages per month (assuming the pages are an average of 10 kilobytes in size). At Dog’s Web Hosting our lowest-cost package offers unlimited bandwidth per month, allowing you to transfer endless pages. You will not find better.

Features and apps

These days it is quite rare to find a web site that consists entirely of simple, static web pages. Normally most sites offer at least some degree of interactivity. There are many examples of interactivity, including:

    forms for users to fill in, which email the data to the web site owner
    databases which contain details of many products on offer
    ability for web site users to upload files such as photos to the web site
    shopping carts
    online learning systems
    online communities and forums

All web hosting accounts offer the ability to store static web pages. If you want interactivity, you need to ensure your host offers the right components. These are available to you through web site scripting. Web site scripting means we offer you the ability to program your web pages to behave in certain ways. Scripting is done using a programming language, and there are several common ones available for web programming including:

    PHP
    ASP.NET
    Java
    Python

For example, let’s say you want to set up a bulletin board to allow your users to hold an online conversation amongst themselves. This would require a database to store all the messages, and the ability to send an email automatically to you when someone has added a new message so that you can review it.

In this situation, we are using at least two components: a database and an email component.

Storing and retrieving data and sending emails are all done via special script which is embedded in your web page. We offer support for several scripting languages, including PHP, Active Server Pages (ASP) and .Net (ASP.NET). The latter two languages are from Microsoft, so if you have any familiarity with Microsoft languages such as Visual Basic, you will be at home here. Furthermore, .NET in fact supports many different languages such as C#, a variant of the C++ language.

Most hosting plans come with the ability to connect to a MySql database. Windows hosting plans can usually connect to a Microsoft Access database, or even an Excel spreadsheet, if you like!
Once I have web hosting how do I get my web site online?

Once you’ve decided on your web hosting package, you will need to design your web site and get it online. This isn’t as hard as it sounds and there are thousands of web sites built by people who’ve never built one before!
WordPress – a brilliant site-building system for absolute beginners and advanced users.

There are many tools and apps available which can help you build your web site. These tools usually allow you to log in to your site and create/edit pages, add images, and add features such as shopping carts or forums.

A great way to start would be with WordPress – a free system which helps you build web sites and blogs. WordPress is incredibly easy to use, and you don’t have to know any technical stuff whatsoever. It also has an extensive collection of free themes available – which means it’s easy to make your site look amazingly professional with just a couple of mouse clicks.

WordPress runs in your web browser, so you don’t have to download any software, and you can edit your site from anywhere in the world. (Fancy updating your site whilst lying on the beach? With WordPress, you can!)

Site-building for those who like to do things by hand
For those who prefer to build their own sites by hand, you’ll need to start with a software program that can create and edit your web pages. An excellent choice is Adobe Dreamweaver, but there are many free web design programs you can download too.

You will initially create your web site on your computer. Once ready, you will then need to upload it to our web servers. As part of the process of ordering your web space, we will have sent you the username and password and other details you need to access your web space on our servers. You must set up your web page editing software with these details. How to do this will vary from program to program, but feel free to contact us for advice on this.

Whichever program you choose, the objective is the same – create good-looking web pages. All these editors allow you to enter text and images into your web pages in a similar way to using a word processor. So if you’re familiar with word processing, this will be quite easy for you. If you don’t want to do this yourself you can of course a professional web design company.

You will then upload your files to our servers. You usually do this using a facility in your site-building software. You’ll need the username and password for your web site to do this – your web hosting company will give these to you when you set up your account.

What about email?

The other half of web hosting is email. All web site owners require email accounts with the same domain name as their web site. For example, if your domain is retroprism.com, you’ll probably want an email address like sales@retroprism.com, or gavin@retroprism.com.

Most web hosting accounts come with a set number of email accounts included, usually between 3 and 10.

Your web host will also give you access your own personal email control panel which will allow you to set up your accounts.
Sending and receiving email

Once you’ve set up your email accounts, you’ll need a way of sending and receiving email through them. There are many ways to access email these days, such as:

    desktop software such as Microsoft Outlook, Outlook Express, Thunderbird
    email software built into your Mac, iPhone, smartphone, Android phone, Blackberry or Windows phone
    send and receive your email via tablets, smart TV and other devices
    WebMail – a web site where you can log into your email account via your web browser
    popular free or paid-for webmail facilities such as GMail or Hotmail.

Provided your email account supports POP3 or IMAP (don’t worry about what these mean) you will be able to use your email through any or all of the above ways.

Where do domain names come into it?

A domain name is your identity on the Internet. For example, the domain name of this web site is dogswebhosting.com. All web sites are reached by a user typing in the domain name to their web browser. Also, all email accounts are related to a specific domain name. To set up a web site you will need a domain name.

Most people purchase their domain names from their chosen web hosting company, either before they purchase their web hosting accounts or at the same time. You can also host a web with a different company you bought the name from.

A domain name that does not have any web space allocated to it and does not have any email facilities is known as a parked domain. This means it is reserved for the owner’s later use.

What are the pitfalls?

As with buying any service, whether online or off-line, there are a number of potential pitfalls that is advisable to be aware of. The world of web hosting is infested with jargon and it is sometimes difficult to understand what your requirements are and how to tell if you are getting a good deal.

Unfortunately there are some unscrupulous companies operating in this area who bring the industry into disrepute. Fortunately, the most common pitfalls are easy enough to avoid as long as you are armed with a little information.

Hidden bandwidth charges

Many companies hide the fact that they offer insufficient bandwidth for you to reasonably run your web site. Check small print for any hidden bandwidth charges. Often extra bandwidth is charged at a much higher rate than your normal allowance.

Hidden domain name transfer fees

Some companies offer very low-priced domain name registration, and allow you to transfer names in for free. However there may be hidden costs if you want to transfer your name away from the company for whatever reason. Some firms are still charging up to £80 to transfer away, which is totally unethical. Most companies allow you to transfer your domain away free of charge.

Lack of technical support

If you are new to web hosting and running your own web site, top-notch technical support will be crucial to you. You need to ensure that you can contact the hosting company and that they will respond in a timely way with an appropriate answer. Support is one area where web companies can really differentiate themselves. Support should ideally be offered through email, web and phone. Many companies also offer online chat support and support forums where customers can help each other.
Finally

We’ve introduced many concepts and gone through some jargon too. We hope this has not put you off. Running a web site, whether for business or pleasure is immensely rewarding.
