Computer processors operate at various levels of abstraction going from the digital logic level up to the microarchitecture level and the machine language level. The main components of a computer system include the processor, the main memory, the disk, and I/O devices

They just differ as it comes to how powerful each piece is, how many CPUs are there, the size of the memory and disk, and so on The levels from problem definition to assembly language are related to the computer science field.

assembly language — low-level language that is designed to be computer friendly. abstraction — removal of unimportant elements of a program or computer code that distract from its process. microarchitecture — architecture, or design, of the processor or microprocessor. disk — storage mechanism for data.
