1. textbook learning
Chapter 4: gate circuit
this chapter to learn the computer running the smallest unit of the door and the base unit circuits. In this lesson made me more clearly understand the mutual conversion between the logical operation of the computer and judgment, different doors and gates, but also let me have a better understanding of the development of computing speed of the computer.
Chapter 5: calculating means
this learning each individual computer components, respectively, to understand their different roles and a preliminary understanding of the concept of memory and its different storage devices. In this chapter made me more intuitively understand the internal structure and composition and operating procedures, stored important role in the development of a computer to computer, other components such as touch screens and the development of embedded systems.
