The term shareware refers to commercial software that is copyrighted, but which may be copied for others for the purpose of their trying it out with the understanding that they will pay for it if they continue to use it.
He used the term freeware for PC-Talk and that was how this word was coined. Within a few months of this, Bob Wallace developed a word processor, PC-Write and called it shareware. But Andrew Fluegelman initially did not distribute the software freely, thus making it a shareware. The Copyright laws are applicable to both Freeware and shareware, and the copyright holder retains all rights.
The authors or developers of freeware and shareware are programmers and their programs are of comparable quality. The software license may impose some restrictions on the type of use of software including personal use, individual use, non-profit use, non-commercial use, academic use, commercial use or any combination of these. The license may be "free for personal, non-commercial use.
The main difference lies with the method of distribution. For freeware, ideally there is no charge for using the software. Under EULA, the author gives the permission to copy and distribute the software, either to all or to a specific group. Freeware distribution gives users a chance to try software and continue to use it for no payment or some acknowledgement Ex. Shareware distribution gives users a chance to try the software before buying it. If someone wants to use the shareware program for a long time then he may have to buy it.
In shareware, the developer omits the normal distribution channel and the retail middleman and directly markets it to the end user.
This results in a reduced end-user price. Shareware is generally written by individuals or small companies, and its quality and level of support vary widely.
In some cases, however, shareware packages are actually more capable than corresponding commercial software, and some commercial programs got their start being marketed as shareware. While shareware may be freely copied, companies may not charge fees for copies that significantly exceed their duplication and handling costs.
The authors of shareware programs also retain their copyright on the contents, and you may not modify such programs or distribute modified copies. Freeware is also distributed at minimal cost, but in this case the authors do not expect payment for their work. Typically, freeware programs are small utilities or incomplete programs that authors release for their potential benefit to others, but without support.
The author of a freeware program may still retain a copyright on its contents and stipulate that others not modify the program or charge significant fees for its use or distribution. Public domain software is not copyrighted. It is released without any conditions upon its use, and may be used without restriction. This type of software generally has the lowest level of support available. Open-source software is jointly developed software that can be used, shared, borrowed, or changed without restriction.
