其中8bit就称为一个字节(Byte)。计算机中的CPU位数指的是CPU一次能处理的最大位数。例如32位计算机的CPU一次最多能处理32位数据。 Bit,乃BInary digit(二进制数)位的缩写,是数学家John Wilder Tukey提议的术语(可能是1946年提出,但有资料称1943年就提出了)。这个术语第一次被正式使用,是在香农著名的《信息论》...
* (divide and conquer). Due to space limit, here is an example for a * 8-bits binary number A=01101100:[1] * | Expression | Binary | Decimal | Comment | * | A | 01101100 | | the original number | * | B = A & 01010101 | 01000100 | 1,0,1,0 | every other bit from A ...
The development ofeight-bitmicroprocessorsin the 1970s popularized this storage size. Microprocessors such as theIntel 8008, the direct predecessor of the8080and the8086, used in early personal computers, could also perform a small number of operations on thefour-bitpairs in a byte, such as the...

For example, it requires 8 bits (1 byte) to store a single character. Capital letter "A" is that number is 01000001. A small case, "A", said binary code is 01100001. Please note that third place is different for each octet. By rearranging bits within the octet, a byte is able to...

public class NumberDis { public static void main(String[] args) { String binaryNumStr = "00100010"; int parseInt = Integer.parseInt(binaryNumStr,2); Console.log("二进制数:{0},对应十进制数:{1}", binaryNumStr,parseInt); // 可直接定义二进制数,以0b或者0B开头 ...
三、bit与Byte的区别与关系 1、bit 位(小写b)),也称比特,是英文 binary digit的缩写,二进制数系统中,每个0或1就是一个位,位是数据存储(计算机中信息)的最小单位,计算机中的CPU位数指的是CPU一次能处理的最大位数。例如32位计算机的CPU一次非常多能处理32位数据。
