布爾代數中的一種運算，它同時(shí)對兩個(gè)二進(jìn)制數字進(jìn)行如下操作：如果一個(gè)數或二個(gè)數為1，則結果為1；如果二個(gè)數均為零，則結果為零。它的邏輯算符是OR運算符。
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.
在計算技術(shù)和通信技術(shù)中，作為一個(gè)整體來(lái)處理的一組8個(gè)二進(jìn)制數字。見(jiàn)octal。
In computing and communications, a group of eight binary digits treated as an entity.
用于表示十進(jìn)制數的一種二進(jìn)制編碼的十進(jìn)制碼，其中每位十進(jìn)制數用七位二進(jìn)制數來(lái)表示，它們分別是8，6，4，2，0，1和0的系數。五－二碼表如下：
A binary-coded decimal code for representing decimal numbers in which each decimal digit is represented by seven binary digits which are coefficients of8,6, 4,2, 0,1, 0, respectively.
一種低速輸入設備，它將圖形和圖象數據轉換成用于數字計算機的二進(jìn)制數值輸入。
A low-speed input device that converts graphic and pictorial data into binary, numeric inputs for a digital computer.
