What type of software can be copied freely and have no license agreements?
Freeware is software distributed for free on the web put
together by software developers all over the world. The Linux OS is
primarily based on freeware. If you have a Mac, Apple has a lot of
freeware available as well. One of my favorite freeware programs is
Open Office, it's an equivalent of Microsoft Word but it is totally
free. They have a version of Open Office for many operating systems
(including Windows, http://www.openoffice.org/).
