计算机如此神通广大,它到底是怎样组成的呢?它又是怎样工作的呢?我们拿它与人来进行一下对比。先看一个人用纸和笔进行手工计算的过程。纸的基本目的是信息存储。纸上的信息存储。纸上的信息可以包括进行计算时应当遵循一系列指令,即算法或程序,以及所使用的数据。如纸上写有这样一道算术题“X=100÷(30+50)”,其中“÷”、“()”等符号就是算法指令,表明运算顺序和规则,而“100”、“30”、“50”等就是数据。计算过程的中间结果和最后结果也将做为信息记录在纸上。大脑可以被称为处理
Computer so magical, it is exactly how it is composed? And how does it work? We take it and people to make some contrast. Look at a man’s manual calculation of paper and pen process. The basic purpose of paper is to store information. Information storage on paper. The information on the paper can include a series of instructions that should be followed in the calculation, ie algorithms or procedures, and the data used. Such as paper written on the arithmetic problem “X = 100 ÷ (30 + 50)”, where “÷”, “()” and other symbols is the arithmetic instructions, indicating the order of operation and rules, and “100”, “30” , “50” is the data. The intermediate results and the final results of the calculation process will also be recorded as information on paper. The brain can be called processing
