If you need to transfer large amounts of data from your Macintosh to another computer, you can store the files on a CD or DVD. A single CD can hold up to 700MB of data, while a single DVD can hold 4.7GB. The newest double-layer DVDs are capable of storing up to 8.5GB of data.
CDs and DVDs are perfect devices for sharing files with others. Just copy your files to a CD or DVD and then mail it or drop it off with your friend. Unlike a hard drive, for example, a CD or DVD is pretty durable, as long as it's kept in its case. Best of all, nearly every computer can read CDs and DVDs, as long as the computer has the right type of drive.
