Freeware	Shareware
Freeware refers to software that anyone can download from the Internet and use for free.	Sharewares give users a chance to try the software before buying it.
The term freeware was first used by Andrew Fluegelman in 1982, when he wanted to sell a communications program named PC-Talk.	In 1982, Bob Wallace produced PC-Write, a word processor, and distributed it as a shareware. The term was first used in 1970, in InfoWorld magazine.
User license or EULA (End User License Agreement) is an important part of freeware. Each license is specific to the freeware. Copyright laws are also applicable to Freeware.	Copyright laws also apply to Shareware but the copyright holder or author holds all the rights, with a few specific exceptions.
All the features are free.	Most of the times, all features are not available, or have limited use. To use all the features of the software, user has to purchase the software.
Freeware programs can be distributed free of cost.	Shareware may or may not be distributed freely. In many cases, author’s permission is needed, to distribute the shareware.
Adobe PDF, Google Talk, yahoo messenger, MSN messenger	Winzip, Cuteftp, Getright
Freeware is free, and is covered by copyright	Shareware is free, can be copied and is covered by copyright.
You can’t sell freeware software and modified software must be freeware.	Shareware cannot be modified, and it may be either a cut down or temporary version.
