凯撒密码(英语:Caesar cipher),或称凯撒加密、凯撒变换、变换加密,是一种最简单且最广为人知的加密技术。 凯撒密码是一种替换加密技术,明文中的所有字母都在字母表上向后(或向前)按照一个固定数目进行偏移后被替换成密文。 例如,当偏移量是3的时候,所有的字母被替换,比如A将被替换成D,B变成E,以此类推。 无规...

The binary numbering system was refined in the 17th century by Gottfried Leibniz. In mathematics and in computing systems, a binary digit, orbit, is the smallest unit of data. Each bit has a single value of either 1 or 0, which means it can't take on any other value. ...

Binary Numbers Binary Notation Writing numbers inbinarynotation means expressing them as a sequence ofbinary digits(bits),either0 or 1. Each number must be represented bypowers of two. Counting from the left, the position represents the exponent of this power. ...
