What is public domain software?
Public domain software concerns software that is not limited to copyright. Therefore, it is possible to use, copy or change freely, because no one does not own the rights to reduce its use. There are plenty of public domain programs, but they are often confused with several other types of software called freeware that can be obtained for free or shareware, which is usually obtained for a very small fee. In most cases, public domain software is the only type that does not apply to any restrictions. Freeware can be protected by copyright and shareware is certainly. This means that it is not basically in a public domain. Someone else cannot reproduce software, copy it to other people or copy it to sell without violating copyright laws. For example, the Bible is the work of a public domain. It can be used, copied, sell, cited, translated or changed without violating the copyrights of several patent authorities. Examples of public domain software is a GNU that makes up part ofMany PC operating systems.
While you find public domain software lists, you can find lists of free software. In most cases, this software is not really in a public domain. Obtaining this means you have obtained a license to use it. If you have ever installed a free computer program, you probably had to accept the conditions for using the software. Some of these terms and conditions you agree with may forbid you to sell, change or benefit from the software in any way.
There are a number of free software programs that are not software of public domains. For example, you can easily get Adobe® Reader®, Netscape®, Internet Explorer® copies and many other programs. Also, when you buy a computer, you can have several free programs but again are licensed, instead of being copied or distributedi.
Public domain software can be found in various places. Several university and university libraries offer downloads and catalogs. The key to science is some of the most interesting software for public domain. Programs such as web and visual molecular dynamics allow you to create three -dimensional drawings of molecules. A great place to find a public domain and free software and shareware is free software Foundation (FSF). You will find lists of public domain software and any software that provides automatic licenses to use specific programs. FSF is also specific when telling you what kind of software you download.
