'''Commodore DOS''', also known as '''CBM DOS''', is the [[disk operating system]] used with [[Commodore International|Commodore]]'s [[Commodore International#6502-based Computers|8-bit computers]]. Unlike most other [[Disk operating system|DOS]]es, which are loaded from disk into the computer's own [[random-access memory|RAM]] and executed there, CBM DOS is executed internally in the drive: the DOS resides in [[read-only memory|ROM]] chips inside the drive, and is run there by one or more dedicated [[MOS Technology 6502|MOS 6502]] family [[central processing unit|CPUs]].<!--I think all of them did; if any used another chip, please correct this.--> Thus, data transfer between Commodore 8-bit computers and their disk drives more closely resembles a [[local area network]] connection than typical disk/host transfers.
