bit shortener

While some information is stored, it does not need to occupy a full byte, only a few or one bits. For example, when storing a switching volume, there are only 0 and 12 states, with one binary. In order to save storage space and make processing simple, C language also provides a data structure, called "bit field" or "bit segment". The so-called "bit field" is to d

Next, I try to give the most detailed answer in the simplest words: the "five differences" between the two ". At the same time, it focuses on the Microsoft Windows 64-bit (x64) operating system. What are the biggest advantages and disadvantages of the 32-bit (x86) operating system? First, the original design is different. The 64-bit operating system is designed t

Windows7 flagship 64-bit and 32-bit difference At present, we are using the WIN7 system, if it is greater than 4GB memory installed users need to pay attention to the system is the number of cases. If the user is greater than 4GB memory, the Windows7 64-bit system should be installed. However, the data width of CPU GPRs (general-purpose registers, universal Re

The bit field of C struct (bit segment) Some information is stored without having to occupy a full byte, which only takes up a few or one bits. For example, when storing a switching volume, there are only 0 and 12 states, with one binary. In order to save storage space and make processing simple, C language also provides a data structure, called "bit field" or "

Bit field (bit) of C structure bodySome information, when stored, does not need to occupy a full byte, but only a few or a bits. For example, when storing a switch quantity, only 0 and 12 states, with one binary can be. In order to save storage space and make processing simple, C language provides a kind of data structure, called "bit field" or "

Many of my friends may not know what is the difference between a 32-bit Windows 7 system and a 64-bit system. I will introduce it to you in detail. The 64-bit Windows 7 system is selected because the memory size is larger than or equal to 4 GB. In 32-bit Windows 7, the memory usage may be 3.xxg. The addressable memory

If you establish a connection server with a 32-bit database server on a 64-bit computer and use the connection server for Distributed queries on 64-bit computers, the following error message is returned: Server: Message 7399 , Level 16 , Status 1 , Line 1 Ole db Provider ' Sqloledb ' Reported an error. [ OLE/DB Provider returned messag

Windows 7 has 32-bit versions and 64-bit versions, but must 64 be faster than 32-bit? First of all, I believe that the choice of 64-bit Windows 7 users in a large proportion of the storage body is greater than or equal to 4GB. If you have 32-bit Win7, the memory that you ca

In short, a 32-bit program can only access a part of the Registry Information on a 64-bit system. To fully access the information, a simple method is to use a 64-bit program. The following is a transfer article: [Original address: http://blog.sina.com.cn/s/blog_592fe54701008d820.html] 1 OverviewCurrently, the computer system has been gradually switched from 32-

1. Data Types, especially int-related types, have different lengths on the platform of machines with different digits. The c99 standard does not specify the length of a specific data type, but only specifies the level. For comparison: 16-bit Platform Char, 1 byte, 8 bits Short 2-byte 16-bit Int, 2 bytes, 16 bits Long 4-byte 32-bit Pointer 2 bytes 32

64-bit programming in front of the 32-bit world in the new era Author: Xie Qidong Source: topic network responsibility Editor: Ark 　　Write portable code for 16, 32, and 64-bit Architectures Compared with 16-bit, 32-bit means faster programs, more memory and better processor

After the server became 64, 64-bit background GP has also come out, and desktop, engine still 32, in use because of this 32-bit and 64-bit problems caused by the attendant. Some of these problems in the product to help provide a corresponding solution, a special summary for your reference. 1. ArcGIS Desktop and ArcGIS Server connection SDE Database (1) OracleIf

Http://blog.csdn.net/zhongzhiwei/article/details/8678885 1) What is the difference between a 64-bit system and a 32-bit system? 1. 64-bit CPU has greater addressing capability and supports up to 16 GB memory, while 32-bit only supports 4 GB memory 2. 64-bit CPU can extract 6

Distinguishing one: the ability to process dataThe CPU of a 32-bit computer can handle up to 32 bits of data at a time, such as its EAX register is 32 bits, and of course 32-bit computers can usually handle 16-bit and 8-bit data. 64 processing data for the computer at one time is much larger than 32 bits, running 64-

How can apps on iOS be compatible with 32-bit and 64-bit systems? When Apple launched the iPhone 5S, the 64-bit application came to the fore. At that time, I saw Apple's official materials announcing that the iOS7.x SDK supports 64-bit applications, and the built-in applications are already 64-

Click to open linkIn 32-bit, 64-bit systems, the only change is the length of the pointer; The 32-bit system is 4 bytes, 64 bits is 8 bytes. This refers to the bit width of the register, which is the so-called three-position . Results under 32-bit platform:Results under 6

What are 64-bit and 32-bit Internet ExplorerIf you experience problems when you use the 64-bit version of Internet Explorer, try using the 32-bit version of Internet Explorer to view the same Web site. If the problem occurs in these two versions of Internet Explorer, you must determine whether the problem is caused by

In general, we'd better compile this platform's binaries on one platform, such as compiling 32-bit programs on 32-bit platforms and compiling 64-bit programs on 64-bit platforms. Now 64-bit systems (mostly x86_64 systems, including AMD64 and Intel's EM64T) have been wide

A bit segment (Bit-field) defines the space occupied by a member variable in a struct (or union) in bits. A struct (union) that contains a bit segment is called a bit segment structure. The use of bit-segment structure can not only save space, but also easy to operate.A

Difference one, the requirements for configuration are different 64-bit operating systems can only be installed on 64-bit computers (the CPU must be 64 bits), and 64-bit common software needs to be installed to perform the best performance of 64-bit (x64), and 32-bit operat
