2. Software - basic concepts<br />
The hardware of any computer, is unusable without software. The software is an instructional<br />
program that shows the hardware, what and how to do. One computer uses different software to<br />
perform different actions - browsing in the Web is a web browser which is a program. Many<br />
programs are also used for processing image and creation of document. These are the two basic<br />
things for a computer, that one can not do without another - software and hardware.<br />
The software is copyrighted and usually has a license to use. It regulates how the creator and the<br />
end user are using it. Licenses provide the user with the right to use the software under certain<br />
conditions.<br />
