CD Burner software is a part of [email protected] Boot Disk. We can use it for information storage purposes, a compact disc (CD) is usually sufficient with its 650 megabytes of available storage space. But if you need more space than that, you can store 4.7 gigabytes on a DVD, up to 8.4 gigabytes on a double layer (DL) DVD (you can record two layers of information on one side). DVD-R (read only) or DVD-RW (read and write, meaning information on these DVDs can be erased and new information can be burned onto them). These are called “dash.”
