Learning a second circumferential part of the computer is the hardware layer.
Chapter 4 and the gate circuit, describes how the operation of various doors and how to construct gate pass transistor. A gate output of the gate as the other input circuit can be combined into a door. Also leads to the concept of the CPU.
Calculating means Chapter 5, relates to various devices constituting the computer. They have their own characteristics, including speed, size and efficiency.
Von Neumann architecture is the underlying architecture of most of today's computers. There are five main components, read - this is the heart of the execution period of the process.
