第二讲一、计算机与二进位数码在第一讲中已谈过,电子计算机的运算是采用二进位制来进行的。为什么呢?现在就回答这个问题。由于二进位制只有0与1两个数码,所以,机器制造时要考虑有没有代表这两个数码状态的物质基础。回答有!因为,只要能表示两种不同稳定状态的电子器件就能用来表示二进位制的数。例如:用电灯的“亮”“暗”,电位的“高”“低”,

Second, a computer and binary digital In the first talk has been talked about, the operation of electronic computing is carried out using the binary system. Why? Answer this question now. Because the binary system has only two digits, 0 and 1, it is important to consider whether or not there is a material basis for the two digital states in machine construction. The answer is! Because, as long as the two different stable electronic devices can be used to indicate the number of binary system. For example: with the light of “light” “dark”, the potential of “high” “low”
