how many bytes in gig

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

Read () errors caused by reading text bytes. read text After several months of work, I had nothing to worry about and started reading the Classic C program design. When I saw the Character Count section, I thought I would use read () to read the text as the character input. everything was OK, when the row count problem occurs, there is no problem with the total number of characters, and the feasible calculation cannot be done. After thinking for a lon

FunctioncheckFileType ($ fileName) {$ filefopen ($ fileName, rb); $ binfread ($ file, 2); read-only 2 bytes fclose ($ file); $ strInfo @ unpack (C2chars, $ bin); C is an unsigned integer, and all found online are c, which is a signed integer, which produces negative numbers and leads to abnormal judgment. $ typeCodeint Function checkFileType ($ fileName) {$ file = fopen ($ fileName, rb); $ bin = fread ($ file, 2); // read-only 2

The error often occurs when opening a text file through the open () function, using the ' RB ' attribute, such as: Filehandle=open (filename, ' RB '), when the file is opened in binary mode, so if the STR () function is used in the later processing, The error will occur, and the error will no longer appear in the Python2.There are two ways to solve the problem:The first, using the ' R ' attribute in the open () function, which reads text, instead of ' RB ', is read in binary file, which solves t

After reading an article published by the srv2 forum, we discussed the application of "besr", which contains a large number of images. In this way, it takes a long time for the viewer to watch it. This is because there are too many images and the total number of bytes is large. If an image is 90 K on average, the 30 images are nearly MB! What's more, srv2 has more than 30 pictures! In this case, during the Forum peak period, the posts are almost invis

Original article Portal Word: In the ARM architecture, the word length is 32 characters, while in the 8-bit/16-bit processor architecture, the word length is generally 16 characters. Half-word: In the ARM architecture, the length of the half-word is 16 bits, which is consistent with the length of the word in the 8-bit/16-bit processor architecture. Byte: In the ARM architecture and 8-bit/16-bit processor architecture, the length of the byte is 8 bits. Arm command line alignment: The address s

Unicode in Windows is a UTF-16, and each word is represented in two bytes. During programming, you can use the text macro and the Unicode and _ Unicode variables defined in the project to ensure that the entire project works under Unicode. Some problems occur when writing strings to files. Write the file using the writefile function, the string itself is UTF-16, after writing the file found that with vim and notepad open are not correctly displayed.

Int * mallocedmemory = (int *) malloc (1024 + 15 ); Alignedmemory = (int *) (INT) mallocedmemory + 15 )~ 15 ); (Void **) alignedmemory) [-1] = mallocedmemory;Return alignedmemory; + 15 instead of + 16 For example, the address 0x00 + 15 is changed to 0x0f ~ 15, or 0x00, so that a 16-byte alignment address will not waste 16 bytes. The address 0x00 + 16 is changed to 0x10 ~ 15, or 0x10, so a 16-byte alignment address will waste 16

One, byte, and UnicodeThe Java kernel is Unicode, even the class file, but many media, including file/stream, are saved using a byte stream.So Java wants these bytes to flow through the line transformation. Char is Unicode, and byte is a byte. The functions of Byte/char in Java are in the middle of Sun.io's package. Where the Bytetocharconverter class is in dispatch, can be used to tell you that you use the convertor. Two of the most common static fun

An integer expressed in four bytes. A total of only 2 ^ 32 is approximately 4G.For the sake of simplicity, we can assume that they are all unsigned integers.Allocate MB memory. Each bit represents an integer, which can represent an integer of 4 bytes. The initial value is 0. The basic idea is to set the corresponding bit location to 1 for each number read. After processing the 40 Gb number, traverse the mem
