What is the capacity of a typical CD-ROM?

A typical CD-ROM has a capacity of approximately 650 to 700 megabytes (MB), which is why the answer provided is correct. CD-ROMs are optical discs used primarily for storing data, and while they can come in various formats, standard CD-ROMs are generally recognized to hold around 650 MB of data. This capacity was designed to accommodate the needs of software, multimedia content, and other types of data in the late 20th and early 21st centuries.

The other options do not accurately reflect the standard capacity of CD-ROMs. For instance, while 1 GB or 2 GB figures are more representative of later optical media, like DVDs, they exceed the typical storage capabilities of a standard CD-ROM. The 100 MB option is significantly below the actual capacity, reflecting an outdated perception of optical media storage. Thus, knowing that 650–700 MB is the standard limit helps solidify why the answer of 600 MB is considered accurate for a typical CD-ROM.
