布尔代数中的一种运算，它同时对两个二进制数字进行如下操作：如果一个数或二个数为1，则结果为1；如果二个数均为零，则结果为零。它的逻辑算符是OR运算符。
An operation performed in Boolean algebra on two binary digits simultaneously in a way that the result is one if either one or both digits are a one, or zero if both digits are zero. The logic operator is the OR operator.
在计算技术和通信技术中，作为一个整体来处理的一组8个二进制数字。见octal。
