Computer as a virtual machine

Describe in brief a six-level computer with a diagram.

Explain in your own words the difference between the compiler and assembler.

In very first computers, the boundary between hardware and software was crystal clear. Over the time it has blurred considerably. Please, justify this statement.

Explain in brief with the help of a diagram the von Neumann architecture.

Explain in brief computer generation from the zero generation to the fifth generation.

The technologist's notion of Moore's Law is that the number of transistors per chip doubles approximately every 18 months. In the 1990s, Moore's Law started to be described as the doubling of microprocessor power every 18 months.

Suppose a transistor on an integrated circuit chip were 2 microns in size. According to

Moore's Law, how large would that transistor be in 2 years?
