Detailed explanation-1: -A CD-ROM (Compact Disc Read-Only Memory) is a type of compact disc that can only be read, not written to. It is a digital storage medium that can hold large amounts of data, including text, images and audio. The data on a CD-ROM is encoded in a spiral track that begins at the center of the disc and extends to the edge.
Detailed explanation-2: -A CD-ROM is read-only, which means the data are stamped permanently into the disc, and additional data cannot be written onto it. CD-R discs (the R stands for recordable) have a dye-based recording layer that allows them to record information like data files, digital photographs, video or audio.
Detailed explanation-3: -The original CD-ROM format is known as Mode 1, and XA is known as Mode 2. There are two sector formats in XA: Mode 2 Form 1 contains all the error correction as in Mode 1. This mode is sometimes the default for CD-R authoring programs, because it provides more compatibility with multisession discs.
