DOS code pages
What does DOS code pages mean?
Definition
DOS code pages are character encoding standards that were used in the original IBM PC-compatible personal computers and early versions of the MS-DOS operating system. Code pages were used to represent text in different languages, and each code page defined a mapping between specific characters and their numerical values. There were several code pages developed for the DOS operating system, including the original IBM PC code page (code page 437), code pages for various European languages, and code pages for languages that used non-Latin scripts, such as Greek and Hebrew.
Code pages in DOS were used to control the appearance of text on the screen and in text files, and they could be changed by switching to a different code page. However, code pages had limited support for internationalization and were often incompatible with each other, making it difficult to exchange text between systems that used different code pages. With the advent of Unicode, code pages have largely been replaced as the primary means of representing text in computers, although they still remain in use in some legacy systems.
