Useful Sites

These are just a few of the sites that I have found extremely useful in my own work. It's something of a personal selection and a bit haphazard but, hopefully, you will find something useful here too!

It is provided by one of the main commercial companies offering broadband services in the UK, but is an objective and reasonably comprehensive list of vocabulary that is in use. Some descriptions are brief, but you can always search elsewhere for more information.
