零和一:数字化基础知识详解

by Mike

使用二进制数字系统对于数字技术来说非常有效,因为电子电路可以轻松区分两种状态,即 0 和 1。这使得处理数据的方式更加可靠。

空和一作为信息的数字形式

数字化是将模拟信息转换为由 0 和 1 组合而成的数字形式的过程。这种二进制数字系统是数字技术和计算机的基础。该系统中的每个数字称为 “比特”,是 “二进制位 “的缩写。

  • 比特和字节:单个比特的值可以是 0 或 1。八个比特组成一组,称为 “字节”。
  • 一个字节可以表示 256 种不同的 0 和 1 的组合(2^8 种可能性),足以表示各种字符、字母和数字。
  • 数据处理: 计算机中的数据处理基于电路和处理器对 0 和 1 的操作和转换。
  • 逻辑运算,如 AND、OR 和 NOT,用于处理二进制数据,以执行复杂的任务。
