7CD-ROM drive
A CD-ROM drive allows optical data media (CD-ROMs) to be read. A CD-ROM
is read using a laser beam, with no contact with the disk itself. Unlike other data
media, it is not possible to write to a CD-ROM (ROM = Read Only Memory).
In the world of Reliant UNIX
®
systems, CD-ROMs are used primarily for distrib-
uting software. Nowadays, however, a wide range of other information, such as
directories of ZIP codes, spare parts catalogs and so on, is available on CD-
ROM.
If the CD-ROM drive is already fitted in your system unit when shipped, the
software is automatically installed and configured when the system is first
started up. In this case you need not read the chapter entitled “Installation“.
