In future, purchase a Mac with greater storage capacity. 120GB is not enough and 256GB would be the new bare minimum for the average user. 512GB for power users and 1TB+ for professional users with large amounts of data.
Here is the short, best answer. When you run out of space on your HD you will need to install an external disk. Then you can transfer files, such as photos or music files to the external disk and that will allow you to delete them from your HD to clear up the needed storage space. These days these disks are cost effective, compact, easy to install with vendor provided USB cables and most do not require external power. You may have to reformat it though. There is a large selection of disks to choose from. This solution will allow you to easily have the storage you need.
