Allowing an individual or group to use a piece of
software. Nearly all
applications are
licensed rather than sold. There are a variety of different types of software licenses. Some are based on the number machines on which the licensed program can run whereas others are based on the number of
users that can use the
program. Most personal computer software licenses allow you to run the program on only one machine and to make copies of the software only for
backup purposes. Some licenses also allow you to run the program on different computers as long as you don't use the copies simultaneously.
