1) If you can already use the internet alone, find Answerbag and type this question, I guess that you have already some basic knowledge - or some help. 2) "Computers store data and the instructions telling them what to do with the data as numbers, because computers can do things with numbers very quickly. These data are stored as binary symbols (1s and 0s). A 1 or a 0 symbol stored by a computer is called a bit, which comes from the words binary digit. Computers can use many bits together to represent instructions and the data that these instructions use. A list of these instructions is called a program and stored on the computer's hard disk. Computers use memory called "RAM" as a space to carry out the instructions and store data while it is doing these instructions. When the computer wants to store the results of the instructions for later, it uses the hard disk. An operating system tells the computer how to understand what jobs it has to do, how to do these jobs, and how to tell people the results. It tells the electronics inside the computer, or "hardware", how to work to get the results it needs. This lets most computers have the same operating system, or list of orders to tell it how to talk to the user, while each computer can have its own computer programs or list of jobs to do what its user needs. Having different programs and operating systems makes it easy to learn how to use computers for new things. When a user needs to use a computer for something different, the user can learn how to use a new program." Source and further information: http://simple.wikipedia.org/wiki/Computer

Here is a new user tutorial so simple all you need to know is where the Enter key is to get started. It's short and teaches only the very basic things: http://tech.tln.lib.mi.us/tutor/ And then there's The Senior's Guide to Computers, which seems pretty thorough: http://www.seniorsguidetocomputers.com/

Easy...practice makes perfect! thats all she wrote :)
