Bit:: The data information processed by the computer is expressed in binary number encoding, and the second binary number "0" and "1" are the smallest units of information, called "bit" or bit (bit).
Byte (byte): In a computer, a "byte" (byte) is made up of several bits. The number of bits made up of bytes depends on the structure of the computer itself. Typically, a microcomputer's CPU uses 8 bits to make up a byte, which represents the code for a c
Private bytes and virtual bytes can be used in Performance Monitor.ProgramMemory usage. in Task Manager, there are also memory usage and VM Size. however, after careful comparison, we will find that the memory usage does not correspond to private bytes, And the VM Size does not correspond to virtual bytes.
In fact
Types of str and bytes in Python3One of the most important new features of Python3 is a clear distinction between string and binary data streams. Text is always Unicode, represented by the STR type, and binary data is represented by the bytes type. Python3 does not mix str and bytes in any implicit way, we cannot stitch strings and byte streams, we cannot search
What is the number of bytes in the Java base data type? (32-bit system)BYTE 1 byte short 2 byte int 4 byte long 8 byte char 2 byte (C The language is 1 bytes) can store a Chinese character float 4 byte double 8 byte Boolean false/true (theoretically occupies 1bit,1/8 bytes, actual processing by 1byte processing)Java is encoded using Unicode. Each byte occupies 8
Arguably the most significant new feature of Python 3 is a much cleaner separation between text and binary data. Text is all Unicode and is represented by the str type, and binary data are represented by thebytes ty Pe. What makes the separation particularly clean was that str and bytes can ' t being mixed in Python 3 in any imp Licit. You can ' t concatenate them, look for one inside another, and generally pass one-to-a function that expects the othe

From: http://wuyuans.com/2012/06/the-length-of-data/
The length of the data type is related to the compiler and the system. For example, the number of data type bytes in a 32-bit compiler in Windows:
CHAR: 1 byteChar * (pointer variable): 4 bytes (32-bit addressing space is 2 ^ 32, that is, 32 bits, that is, 4 bytes .)Short INT: 2 bytesINT: 4 bytesUnsigned INT:
When IOS uses APNS to push Payload in bytes, the push fails.
In the past two days, you need to add a script to the push. You can add a script to the badge method. However, the push fails. I have been depressed for a long time and search for relevant information online.I finally found the reason:"Payload -- a maximum of 256 bytes."It turns out that the payload Bytes
The most important new feature of Python 3 is probably a clearer distinction between text and binary data. Text is always Unicode, represented by the STR type, and binary data is represented by the bytes type. Python 3 does not mix str and bytes in any implicit way, which makes the distinction between them particularly clear. You cannot stitch strings and byte packets, search for strings in a byte packet (o
BYTE (byte) is B: A byte is made up of 8-bit binary digits (1 byte = 8 bit). Byte is the most common base unit in the information store.
An English letter (case-insensitive) occupies a byte of space, a Chinese character occupies two bytes of space.Symbol: English punctuation 2 is a byte, Chinese punctuation is two bytes.
A binary numeric sequence, as a digital unit in a computer, typically a 8-bit binary

Learn the bytes of Python every day.The byte code in Python is b‘xxx‘ represented in the form. X can be expressed in characters, or in ASCII encoding, with an \xnn NN of 256 characters from 00-FF (hex).Basic operationsThe following is a list of the basic operations of the byte, you can see that it is very similar to the string:In[40]b = b"abcd\x64"In[41]bOut[41]b‘abcdd‘In[42]type(b)Out[42]bytesIn[43]len(b)Out[43]5In[44]b[4]Out[44]100 # 100用十六进制表示就是
