Freeware:

Freeware is software that is available free of charge. freeware is distributed without charge, also usually through the Internet or computer users groups. Why would any software creator let the product go for free? Sometimes developers want to see how users respond, so they can make improvements in a later version. sometimes it is delivered for some learning purposes, such as to create a standard for software on which people are agreeing because there is no need to pay for it.

Freeware developers often retain all rights to their programs, so that technically you are not supposed to duplicate and distribute them further. Still, there is no problem with making several copies for your own use.
