What are the ways in which computer users would use a CD-ROM drive at home?

A CD Contains Data in Tiny "Bumps" and "Lands". Information on CD is stored this way.¨

A Laser Reads the Bumps on a CD. A CD's bumps are so tiny, far too small for a human eye or mechanical device to detect, but large enough for a laser to read.

Light Sensors and Processors Interpret the Data as each bump each kept on the CD as 1 and 0(binary). This processor interprets the ones and zeros to assemble bytes of data which can then be forwarded to the computer's main processor for interpretation. The computer interprets this data as it was originally written on the CD, whether as a complex computer program, a basic collection of files or even simple music. As technology progresses and processor speeds increase, the CD can be spun at higher and higher rates, allowing the data on the disc to be read and sent to the processor, interpreted and used more quickly.
