Q

CCD

A

(Charge Coupled Device)

A type of microchip widely used as a digital image sensor. Each element in a CCD converts light captured by a photodiode into a proportional electric charge, which is then amplified, sampled, and stored as a digital value. The number of elements determines the resolution.

Q

CD-ROM

A

(Compact Disc - Read Only Memory)

An optical storage technology. The discs can normally hold 700 MB of data or 80minutes of audio data. Recordable and re-writable CDs (and DVDs) are a popular backup solution for home users. They are also useful for archiving material. Unlike magnetic media, the data on the disc cannot be changed (assuming that the disc is closed to prevent further rewriting in the case of RW media). This makes them useful for preserving tamper-proof records.
