计算机科学导论习题答案（Introduction to computer science, exercises, answers） Introduction to computer science, exercises, answers Chapter 1 I. multiple-choice questions 1-5, A, D, B, D, D Two. Fill in the blanks [1] fast processing, large storage capacity, high reliability and high accuracy [2] tubes, transistors, small and medium scale integrated circuits, very large scale integrated circuits [3] not having their own ideas, no good intuition and imagination, speed and memory capacity is far from meeting the actual needs Three. Questions and answers [1] the development of computers is divided into five generations: The first generation: components using electronic tubes, large size, slow speed, the machine provides the original instructions to prepare procedures. The second generation: components using transistors and printed circuit, the volume has been reduced, the function continues to increase, you can run assembly language and high-level language, a large number of applications appear. The third generation: using small and medium scale integrated circuits, the system management program is raised to the operating system. The fourth generation: Based on large-scale integrated circuit and very large scale integrated circuit, more powerful, smaller size. The fifth generation: artificial intelligence computer.
