Which Win8, 32-bit or 64-bit should be installed? Now it's nothing new to install Win8. If you haven't installed Windows 8 yet, it's too much to be installed. Ah, wait. Before installation, you have to figure out which version of Windows 8 is to be installed, including the core version, professional version, and Enterprise Edition, we will not bother to explain it to you one by one. Today we will talk about

Now it's nothing new to install Windows 7. If you haven't installed Windows 7, it's too much. Speaking of the advantages of Windows 7, it's a bunch of things, so don't hesitate to install one. Ah, wait. Before installation, you have to figure out which version of Windows 7, family edition, Professional Edition, and flagship edition you want to install. That is the love of radish cabbage, let's talk about another version classification today. That's right, it's the 32-

But the answer I run in TURBO C is 1.Is the running result different because of the turbo c version?I used it in TURBO C V2.0.

I believe there are many people who are not very clear about the difference between 32-bit programs and 64-

64-bit computing has grown into our lives, and 64 of MacOS, Linux and Windows Server systems have become the main players, and 64-bit Windows clients have been well promoted. However, the 64-bit is a lot of people "daunting", because everyone is unfamiliar with the characteristics of 64-bit computing, but also worry ab

run a 32-bit programThe WOW64 subsystem enables 32-bit programs to run without modification on the x64 version of Windows Server 2003 and the Windows XP Professional x64 version. The WOW64 subsystem is created by the x64 version of Windows Server 2003 and the Windows XP Professional x64 version of the 32-bit environment. For more information about the WOW64 subsy

Generally speaking, 32-bit and 64-bit systems have two differences: hardware and software. Hardware:The 64-bit and 32-bit architectures are different. Here, the 64-bit technology is relative to 32-bit, which refers to general-purp

byte order (byte order) and bit order (bit order)? In network programming, the network byte order and host order are often mentioned, that is, when an object consists of multiple bytes, it is necessary to pay attention to the order of the objects ' multiple bytes in memory.Before, I have basically only understood the byte order, but one day when I saw ip.h in the IP head struct struct IPHDR definition, I fo

1. What we call a 64-bit CPU architecture refers to the 64-bit memory expansion technology, which is an extension of the 32CPU architecture and is compatible with the original architecture. It increases the bit width between CPU and memory by increasing the operation bit width of the CPU, thus allowing the system to su

64-bit Visual Basic for Applications OverviewMicrosoft Visual Basic for Applications (VBA) is the Visual basic version that is included with Microsoft Office. In Microsoft Office 2010, VBA includes language features that enable VBA code to run correctly in both 32-bit and 64-bit environments.Note By default, the 32-bit

We usually hear about the differences between 64-bit and 32-bit machines and 64-bit software. In fact, a complete 64-bit computer applicationProgramIt should be like this: The computer's CPU is 64-bit, that is, the computer's Hardware supports 64-

Reading Tips: with the advent of a low-cost 64-bit platform, coupled with the falling price of memory and hard disk, it is undoubtedly a great effort for 32-bit programs to port 64-bit hardware, those scientific operations, databases, and programs that consume a large amount of memory or intensive floating-point operations are also taking advantage of this ride.

What is the difference between the 32-bit and 64-bit Windows system? How do I determine 32-bit and 64-bit systems? Whether the computer architecture is 32-bit or 64-bit depends on the processor (CPU) inside the machine. Currentl

Recently done in the Windows XP x64,vs2005 environment to do 32-bit programs to compile the work of 64-bit programs, encountered some of the 64-bit programming may encounter problems: such as inline assembly (the solution is changed to C + + code), a long type of change, The most critical issue is encountering a 64-bit

Recently, I want to compatible my program with a 64-bit system. I thought it was a big project. However, after reading the relevant information, I found this is not difficult. Because the General 32-bit program can run in a 64-bit System (of course, the general situation), this is mainly because the 64-bit system has c

Question: How are you sure the machine will run a 64-bit kernel? Answer: Running the 64-bit kernel requires 64-bit hardware. For AIX 5.2, all IBM eserver pseries 64-bit hardware can run 64-bit or 32-bit cores. The order is as fol

With the Win7 system becoming the mainstream of the current PC system, many users are already ready to replace their personal computers or corporate computer systems with the Win7 system. Win7 's old users may be more aware that the Win7 system will have x86, 32-bit (32bit) systems and x64 64-bit (64bit) systems. See a lot of users here may be confused, to change the system, then how do I choose? is the 64-
