First, the binary concept
When the accumulated figures, the mechanism is called binary carry on.
1. Decimal
Every decade a
0 1 2 3 4 5 6 7 8 9 10 11 ...
2. Binary
The computer can handle many different types of data, but the underlying computer are ultimately digital storage and processing.
Based on consideration of the convenience of computer hardware, the underlying computer data storage and processing are carried out in binary form.
Every binary a
0 1 10 11 100 101 110 111 1000 1001 ...
3. octal
Computer bottom are binary, but people are not used to see very binary, and convert between binary and decimal relatively trouble, so people made octal
Eight is the third power of two, that is, each corresponding to a three octal binary, very easy to convert
Every eight into a
0 1 2 3 4 5 6 7 10 11 ...
4. Hex
And octal, just as people in order to facilitate the conversion of binary and hexadecimal manner proposed by
Sixteen is two fourth power, that corresponds to a hexadecimal every four binary, very easy to convert
Every hex a
0 1 2 3 4 5 6 7 8 9 A B C D E F 10 11 ...
Second, the conversion between hex
1. binary decimal turn
In addition to 2 by the binary representation of the decimal modulo calculation:
2. Binary Coded Decimal
3. octal binary transfer
Will be converted to binary spliced together to every octal
4. Binary octal
From back to front, one in three is converted to an octal number, you can splice
5. hex binary transfer
Each one hex into binary can be spliced together
6. Binary hex
From back to front, one in four is converted to a hexadecimal, you can splice
Third, the binary unit
Inside the computer, each one is called a binary bit ( 'bit), referred to as bits, also referred to as bins.
而每八位二进制组合在一起，称之为一个字节（Byte）
每1024个Byte，称之为一个KB
每1024个KB，称之为一个MB
每1024个MB，称之为一个GB
每1024个GB，称之为一个TB
每1024个TB，称之为一个PB
