Technical Glossary

The Technical Glossary page on Digital Speak is still a work in progress and designed to help provide the explanation behind some of the terms or acronyms that pop up on the blog.  Most of the entries are linked to a useful website called TechTerms and some are linked to Wikipedia.org.

The list is not exhaustive and will grow with the posts.  If I’ve missed any terms that are in the blog posts but not in glossary and should be, please let me know.

It's updated regularly to keep up with the contents of the posts.
