We have heard these terms a lot of times Open Source and Freeware Software. But do you what is the difference between the two terms? If not, I will tell you that in this post. If you know the difference, please post in comment if i miss out anything important or unimportant.
Open source software is software whose source code is freely available (i.e., without any requirement for payment or any other obstacles) for anyone to inspect and study.
A Freeware software is a software that is available for anyone to use for free(i.e. without paying anything to the company or the programmer).
The user can not modify the source code of such a software. He/she requires the written permission from the author of the software to edit it. If permission is not taken, legal action can be taken against the person.
Source code is the version of software (usually an application program or an operating system) as it is originally written (i.e., typed into a computer) by a human in plain text (i.e., human readable alpha numeric characters). Source code can be written in any of the several thousand programming languages in existence, but it is usually written in one of the dozen or so of the most popular (particularly C, C++ and Java). Without source code it is very difficult to study, modify and improve software.
