CD-ROM and DVD

A CD ROM is a type of optical disk capable of storing large amounts of data - a typical single CD ROM has the storage capacity of around 480 floppy disks. CD ROMs are particularly well-suited to information that requires large storage capacity.

DVD (digital video disc or digital versatile disc) is essentially a bigger, faster CD that can hold cinema-like video, better-than-CD-quality audio, and computer data. Much better than consumer videotape and generally better than laserdisc, it can give near studio-quality audio and video reproduction. See dvddemystified.com/dvdfaq.html

To produce a CD ROM or DVD a Writer is needed. Older drives may read CDs and DVDs, but only write to CDs.

An extensive range of CD ROMs exists on RE related subjects. They will provide plenty of ideas to help prepare the work to be done.
As well as checking what resources are held locally, www.reonline.org.uk/itre provides a search facility to investigate CD-ROMs, DVDs, Videos, etc.

For ideas on what makes a good CD-ROM useful guidance is to be found on Becta's website. It is usually best to develop the material on a computer's hard drive and only write it to the CD when it is finished.
