The monitor is an interactive program in computers, especially in the 1970s, which makes it possible to control a computer at a low level: viewing the contents of RAM and processor registers, executing machine code, disassembling , loading the operating system, etc. Often the monitor was stitched into the ROM of a computer. In some computers, a MOS is installed instead of a monitor ( Monitor Operating System is a monitor operating system).
As a rule, the monitor supported a very limited input language: usually these were hexadecimal numbers, encoding addresses and data, as well as single-character commands; sometimes also symbolic assembly language commands if the monitor included a mini assembler.
Currently, monitors are out of wide use due to the transition in most cases from the use of low-level assembly languages to high-level languages. In this case, instead of monitors, debuggers began to be used, allowing them to work in terms of high-level language.
