how many bytes in gig

The recent conversion of a piece of py2 code to the PY3 code, the result of running to the socket to write data in the code part of the ' STR ' does not support the buffer interface such a mistake.After a search, it was found that Py3 was strictly distinguished from Str and bytes. How do you understand str and bytes? You can think of Str as a piece of text, like "abcd#%$^*" or something, and

First, IntroductionIn order to unify the world's character sets, the Unicode character set is popular, Java also supports Unicode encoding, that is, in Java the code point value is stored in, that is, either ' A ' or ' medium ' occupies two bytes.Code point value: The code value corresponding to the character typeface in the Unicode encoding table;Code unit: A char in Java, which can be a basic unit that is considered a character encoding Second, the code to intercept the string based on byte im

Fopen + fread ($ fp, number of bytes read) originally used by RT) if I want to change the data obtained from SAE to curl, I only need to match the title value and delete the first 800 bytes of the file. There are many curl parameters and I don't know which one to set. After all, retrieving the entire html file will consume a lot of time... RT Originally used fopen + fread ($ fp, number of

In the I/O class library, Java.io.InputStream and java.io.OutputStream represent byte input streams and byte output streams, which are abstract classes that cannot be instantiated, and the smallest unit in the data flow is bytes, so it is called a byte stream.The method of reading data in InputStream is as follows:1, int read ()Function: Reads a byte of data, and returns the read data, and if 1 is returned, it reads to the end of the input stream.2, i

Believe that every computer users know that the computer connected to the network, the local connection to connect, and send packet bytes and received packet bytes both to normal, the network can be used normally, otherwise there will be such or such a problem. However, sometimes people will encounter the local connection received packet bytes very little situati

Because of the different operating system memory allocation, resulting in the software development process, the need to compile different versions of software, here with VS for example. 1, compile the program according to need to choose different compilation environment: X86 and Win32 bit 32-bit program, X64 64-bit program, can choose different editing conditions to form different bits of software. 2, the basic data type in the code, will be based on the operating system's number of digits alloc

All files are stored in bytes. What is stored on the disk is not the character of the file, but the characters are first encoded into bytes, and then stored on the disk. When reading a file (especially a text file), it is also a byte read to form a byte sequence.Int I = 7 so I is a character. in Java, two bytes are used to indicate that the value is 0x0007. _____

First, let's take a look at this question: "Howmany bytes is the memory space in the Java language that the string" java "occupies? "To answer this question we must first understand what is" byte "and what is" character ". byte: bytes are units that transmit information over the network (or store information in hard disks or in memory). Bytes are a unit of measur

Text is always encoded in Unicode, denoted by the STR type, while binary data is represented by the bytes type.In Python3, it is not possible to mix str and bytes types in any implicit manner. STR and by
