How are modern computer systems multileveled? This view of hierarchy

Modern computer systems are divided into multiple hierarchical levels by function, namely, hardwired logic level, microprogram level, conventional machine level, operating system level, assembly language level, high-level language level, and application language level.Designing computers using this hierarchical view ensures that a good system structure is produced.

The concept and technique of using a series of levels to compose a computer provides a good structure and system for understanding how computers are composed.
