Overflow is a classic example of the type of problems we encounter by mapping an infinite world onto a finite machine. No matter how many bits we allocate for a number, there is always the potential need to represent a number that doesn’t fit. How overflow problems are handled varies by ...
4. Bits & Bytes: 1 byte = 8 bits ;bit只存储1或0的信息(*),8个为一组,组成的一个Byte有256种排列组合方式(也即:取值范围),0-255,所以之前课上图片的示例中,像素的取值范围最高到255,一个byte为单位进行数据存储。(*教授生动的举例视频1分20秒:Course | edX) 5. 计算机数据计量单位:KB-->MB--...
有一个专门处理真假的数学分支的存在,已经解决了所有法则和运算:布尔代数(Boolean Algebra),在布尔代数中,变量true和false进行逻辑操作。 三个基本操作:NOT:翻转布尔值 AND OR 将晶体管类比为水龙头,gate是控制水流的龙头 在not中我们将上面看做输出,左侧看做输入 and gate 为两个二极管串联 or gate: 有两个输入...
