It’s the command processor’s job to carry out the user’s commands entered from the system prompt without having to wait for device-specific instructions. For example, when a user issues a PRINT command, the command processor directs the output to the line printer via BIOS. Similarly, with a user command to TYPE a file, the command processor directs the output to the monitor. In these cases, the user doesn’t need to compensate for the slow speed of the printer and the fast speed of the terminal; the user can interact with both devices and files in the same way.
