A common issue, when reading a description on how to do something, is the language used. Too often the author presumes that their audience knows about the terms being used or understand the abbreviation and or acronyms.
Some authors address this very well and also add in pictures to emphasise their point. However there is a significant stumbling block, which can hinder the most helpful author and this stumbling block can be the organisation who produced the application or item being described.
A number of years ago a it was often said that a document, or book, describing technical aspects went out of date within six months.
Today, because of the speed that organisations change their apps or devices, this time frame is greatly reduced and now a book or article, may be out of date by the time it is published (because of the time lag from when the final draft is submitted, through to printing and release).
Differences can be minor, for example a screen layout in an app may change, but you should always bear this in mind when using an article or book to help you – This doesn’t mean that such sources are useless (you may still be able to work it out) but just be aware of the issue.
The same is true to some extent on IT dictionary’s, and again you should consider using additional sources to find the information you need such as a search engine (Google or Bing) or Wikipedia.
