From bit, Byte, KB, MB, GB, TB to PB, EB, ZB, YB

Do you know how much data the bit, Byte, KB, GB, TB, etc. all mean? Have you ever heard of Pb, EB, ZB, YB?

Bit (bit) is the English abbreviation of binary digit, the unit of measuring information, is also the smallest unit that represents the quantity, only 0, 12 kinds of binary states. The 8 bit consists of a byte (byte) that can hold an English character. A Chinese character requires two bytes of storage space, and ordinary English words require about 10 bytes.

1, bit (bit)
From the English bit, transliteration is "bit", indicating bits. Bits are the smallest unit of data storage within a computer, and 11010100 is a 8-bit binary number. A bits can only represent 0 and 12 states (21); Two bits can represent 00, 01, 10, 114 (22) states; a three-digit binary number can represent eight states (23) ....
2, Bytes (byte)
bytes from English byte, transliteration as "special", used to use uppercase "B" to express.
Bytes are the basic unit of data processing in a computer. The computer stores and interprets information in bytes, which specifies that a byte consists of eight bits, or 1 bytes equals 8 bits (1byte=8bit). Eight-bit binary number minimum is 00000000, the maximum is 11111111; usually 1 bytes can be stored in an ASCII code, 2 bytes can hold a Chinese character GB code.
3, the word
When a computer is processing data, the length of time it accesses, processes, and transmits is called word. A word is usually made up of one or more bytes (usually the integer bits of bytes). For example, the word 286 microcomputer consists of 2 bytes, its word length is 16;486 microcomputer's words are composed of 4 bytes, it is 32-bit in length.
The word length of a computer determines the actual number of bits that the CPU handles at a time, thus the larger the length of the computer, the better its performance.

The progression from byte to top is kilobyte (KB), megabyte (MB), GigaByte (GB), TeraByte (TB), Petabyte (PB), ExaByte (EB), Zettabyte (ZB), Yottabyte (YB). 1KB is 1024 bytes, or 2 of 10, about 10 3, 1YB is 2 of the square, about 80 10 bytes, the complete write down is 24.
