Answer:
D. digital logic level through machine levels
Step-by-step explanation:
In Computer science, the modern computer systems are basically organized in levels and this is known as computer hierarchy. The three levels in a chronological order are operating system level, machine language level and digital (hardware) logic level.
A digital logic level is the most fundamental level of a computer and can be defined as a level of the computer hierarchy which typically comprises of wires and gates. In digital circuits, the two (2) main logic level of the binary logic state are logical low and logical high which is typically denoted by the number 0 and 1 respectively.
In Computer science, the Infrastructure as a Service (IaaS) replaces the digital logic level through machine levels of the computer hierarchy with an Internet-based infrastructure. This is what enables various users to access resources that are available over the internet through the use of cloud storage.
