Here is the spot to begin learning about computers. It is not really all that difficult, but there is definitely a vocabulary that includes symbols. Over the years these have become quite uniform among different programs and presentations you will see. So after an initial orientation and familiarization you will be able to use the same information over and over. So push through and soon the incredible resource of the Internet will by yours.
AARP and the San Bernardino Public Library offer free online courses to familiarize you with computers. These are great places for people new to computers to get their initial orientation.
Free courses are also available to teach you about Microsoft Office and the excellent free Open Office software which is my favorite.
Google is a wonderful resource and searching is only the beginning. So there are some Google Help pages that provide the basics of searching.
