The Computer Museum is a museum in Boston that has lots of good information about computers. Go to the museum to find out more by clicking on this spinning ball. A computer can not work without software. Software is usually stored on disks or tapes by magnetizing particles on the surface of the disk or tape. These disks include floppy disks, hard disks, and zip disks.
Software is stored on CDs by burning pits onto the surface of the disk using a laser beam.
You can not see software. It is like the music or voice on an audio tape. A tape player can play the tape so that you can hear the music. The disk drive can read the disk. Hardware is physical - software is not.
