CD-ROM
CD-ROM (Compact Disc Read-Only Memory) is a type of optical disc used to store digital data. It was first introduced in 1982 and became popular in the 1990s as a means of distributing software, multimedia, and other digital content. CD-ROMs have a storage capacity of up to 700 MB and can be read by a CD-ROM drive, which uses a laser to read the data stored on the disc. In the context of space and astronautical engineering, CD-ROMs have been used to store data and software for space missions, including scientific data and images from space telescopes and probes.
