The difference between 32-bit systems and 64-bit systems has the following four points:
First, the CPU requirements are different
CPU has 32-bit and 64-bit, 32-bit CPU can only instal
First, the original design is different. The 64-bit operating system was designed to meet customer needs for a wide range of memory and floating-point performance in areas such as mechanical design and analysis, three-dimensional animation, video editing and authoring, and scientific computing and High-performance computing applications. In other words, they are the running platform for High-tech personnel
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:

It is easy to use C # To implement the reading and writing of the Registry. I will not explain it in detail here.
Using C # To operate the registry, the two main functions are as follows:ProgramNote: To introduce the Microsoft. Win32 namespace ):

When Apple launched the IPhone5S, 64-bit apps came to the front. At that time, I saw Apple's official profile announcing that Ios7.x's SDK supports 64-bit applications, and that the built-in apps are already 64-bit.I remember I had a 16-
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-b
When a user buys a Windows installation disk or re-installs the operating system, they usually encounter this problem, that is, do not know how to choose to use 32-bit operating system and 64-bit operating system, some people say that the 64-bit system is fast, in fact, in t
Because of the dynamic library called in the project, these dynamic libraries are placed under C:\WINDOWS\SYSTEM32, but when deployed to a 64-bit machine may be problematic, recently this problem has been tangled for a long time, in the native 32 for the system test dynamic call DDL successfully, deployed to 64-bit win

First of all, I believe that the choice of 64-bit WINDOWS7 users in a large proportion of memory is greater than or equal to 4GB. Under 32-bit Windows7, it is possible to show that memory can be used 3.25G, which makes many netizens feel uneasy. Yes, addressable memory space is indeed the most notable feature of the 32-bit
The latest computer configuration is better than a few years ago, the use of XP system is no longer suitable for the full performance of the computer, so the Win7 system is currently the best choice. Win7 and the previous XP system, also divided into several versions, now users generally choose win7 32-bit or 64-bit system, then the two versions of the Win7 syste
because dynamic libraries are called in the project, these dynamic libraries are placed under C:\Windows\System32, but they may be problematic when deployed to a 64-bit machine. Recently this problem has been entangled for a long time, in this machine 32 for the system test dynamic call DDL succeeded, deployed to the 64-bit
The difference between the 32-bit and 64-bit Win8.1 system is actually the difference between the 32-bit system and the 64-bit system, which generally includes the following and major differences.

For the average user, it will certainly take into account that, since the existing 32-bit version of Windows is still used well, why upgrade to 64-bit, and because 32-bit and 64-bit hardware (mainly
We usually use 32-bit machines for development and install 32-bit software, but our servers are generally 64-bit, so sometimes a VS debugging program needs to be installed in a 64-bit environment. Recently, a problem occurs when a
