'''Read only''' is a term usually used in the field of [[computer]]s. The meaning of this term is fairly straight forward; it means simply that something may be accessed and read, but not changed in any way. This attribute can be voluntarily set with [[software]] only for the purpose of protecting one or more files. In some cases however, it can be a necessity. Optical disks are probably the best example of something which is read-only by necessity. [[CD-ROM]]s and [[DVD]]s which are not re-writable can only be written to once. After the data is recorded and the disk finalized, there is not way to add, change, or remove data. | '''Read only''' is a term usually used in the field of [[computer]]s.
