Shares
It means free software, not paid, but shared with everyone.
However, there are some time-limited paid software, also known as shareware. Shareware is a copyrighted software that is sold "first-use and then paid". Based on the authorization of the shareware author, users can get copies of it free of charge from various channels, or they can spread it freely. Users can always use or test the shareware first, and then pay the author if you think it is not worth your money, and you can stop using it.
Sharing software
It is free (or close to free), at different levels than the store-bought kind. Shareware can be downloaded directly from the Internet to your desktop, and it is developed by people who develop programs that are shared with people. And, like commercial software, shareware is protected by copyright law.
The most obvious advantage of shareware is a free trial period. But free trial usually has some limitations, different types of shareware and different authors may adopt different restriction strategies: time limit, such as 30 days, from the start of your installation, 30 days after the registration code is still not purchased, you can not continue to use the software. Functional restrictions, such as a financial software, can limit the trial version of the report printing and export functions. Add a watermark (link), in the generated or exported files to add a trial version of the watermark, which is more suitable for picture processing software, video processing software, Flash software. There are also links to Web sites where software developers are added. Batch limit, you can experience the function without a time limit, but you can only use software to process (save) limited content at a time, such as a trial version of a video format conversion software can only save the 3 minute length of the converted video.
Shareware is a free trial, but not a free use. In fact, the sharing of software is more of a marketing model, often referred to as a try before you buy, that is, "first trial, after purchase", you can let users before the money to experience the software. Small to a CD to MP3 conversion software, large to Microsoft Office and Vista operating system, you can download to try some, feel good again to buy money. Because of the above trial limit, users in order to be able to use the software for a long time, or need to obtain the full functionality of the software, and do not want to have a watermark or the software author's website link, you need to purchase a registration code (user name + serial number) to the software author, after registration can be released from the trial version The price of small software is generally below 100 U.S. dollars, usually 20-40 dollars; professional and powerful prices vary considerably from hundreds of to thousands of dollars.
There are no existing laws forcing fees for shareware.
