Each “How Does:” article deals with a specific aspect of computing. They are written to help people who have no technical grounding and are not interested in the technical detail but want a general idea of how something works. Consequently they are written to aid understanding and won’t contain detailed technical explanations; generally there are plenty of those available on the web. In all cases the “How Does:” articles are based on subjects we are often asked by our customers. For a list of the ones currently available click here southcot.co.uk/WP/index.php/tag/how-does.
