覚え方のコツ Memory Tip
CDとROMに分け、ROMをread-only memory「読むだけの記憶媒体」と押さえるのが要点です。つまりCD-ROMは「読み取りはできるが、自由に書き換えられないCD」です。software on CD-ROM、insert a CD-ROMのような表現と、USBメモリーが普及する以前のソフトや辞書の場面を結び付けると定着しやすいです。
Divide CD-ROM into two familiar abbreviations. CD means compact disc, and ROM means read-only memory. The key phrase is read only: a computer can access the stored information, but the ordinary user cannot rewrite it as on a writable storage device. Picture older software or an electronic dictionary arriving on a disc, followed by the instruction “Insert the CD-ROM into your computer.” Also learn software on CD-ROM. This format was especially common before downloads and USB drives became standard ways to distribute large collections of computer data.

CD-ROM の語源・成り立ち Etymology
compact disc read-only memoryの略です。CDはcompact disc「小型光ディスク」、ROMはread-only memory「読み取り専用メモリー」を表します。市販ソフトや辞書など、変更させないデータの配布に広く使われました。
CD-ROM is an initialism of compact disc read-only memory. CD identifies the physical optical-disc format, while ROM describes data designed to be read without being changed through normal use. The term was created for compact discs used to distribute fixed computer data rather than primarily recorded music. CD-ROMs became a major medium for commercial software, games, encyclopedias, and dictionaries before internet downloads and high-capacity portable storage became widespread.
