Digital audio required space = = 1 song = 27.2 MB Storage math

Kilobytes (KB) 1000 = 1 MB Used to measure text, email, small files Storage math Megabytes (MB) 1000 KB

1000 MB = 1 Gigabyte Used to measure Office documents Floppy disk =1.44 MB Storage math Gigabytes (GB)

1 GB=1000 MB 1 GB=694 floppies Used to measure BIG files, like video How we measure hard drives now Storage math 1000 KB = 1 MB (email in KB)

1000 MB = 1 GB (docs in MB) 1000 GB = more space than your really need right now = 1 song = 27.2 MB Digital audio required space

Storage space (hard drives) were: Expensive Big and clunky Slow Old: 1989 20 MB Hard drive $899

Old: 1995 1 GB Hard Drive $849 = 1 song = 27.2 MB = 1 GB Hard Drive

($899 in 1995) Would hold 35 songs So, NOW why all of the QuickTime and a TIFF (Uncompressed) decompressor are needed to see this picture.

Why the fuss now? Storage drives got cheap Storage drives got small Audio compression got good 1 song = 27.2 MB 1 song = 2.4 MB or less
