Introduction to Open Source Software:
Most software we use is "closed source." Software happens in two
parts. At first human beings write the code that creates the
software. The code is the "Source" and can be edited and changed
by humans. After the "Source" is written it is compiled into
machine language that runs the computer.
"Closed Source" software means the "Source" code is protected by
copyright and can not be changed or altered. Examples of closed
source software are the entire Windows Operating System and Microsoft
In "Open Sourced" software the source code is available to the public
for inspection and changing. The General Public License allows
this software to be freely distributed and used.
Open Source software provides a great opportunity for school systems to
aquire and adapt many software applications for very little cost.
While in Elementary School we will not edit the source code - there are
many free software programs we can provide to our students at school
and at home.
