Distinguish between open source and closed source programs
What will be an ideal response?
The term open source means that the source code of the program is available to the public. Source code is computer code as written by humans and understandable by humans. Source code is compiled into machine code that is processed by a computer. Machine code is, in general, not understandable by humans and cannot be modified. In a closed source project, for example Microsoft Office, the source code is highly protected and only available to trusted employees and carefully vetted contractors. The source code is protected like gold in a vault. Only those trusted programmers can make changes to a closed source project. With open source, anyone can obtain the source code from the open source project's Web site. Programmers alter or add to this code depending on their interests and goals. In most cases, programmers can incorporate code they find into their own projects. They may be able to resell those projects depending on the type of license agreement the project uses.
