Introduction to CD-ROM
A single disc can hold more than 600 megabytes of data (~ 400 books of the textbook’s size)
CD-ROM is read only. i.e., it is a publishing medium rather than a data storage and retrieval like magnetic disks.
CD-ROM Strengths: High storage capacity, inexpensive price, durability.
CD-ROM Weaknesses: extremely slow seek performance (between 1/2 a second to a second) ==> Intelligent File Structures are critical.
