The difference between "literacy" "32-bit and 64-bit Windows

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 theory is true, However, depending on the actual hardware situation of your personal computer, you have to choose.

Overview of 32-bit and 64-bit Windows operating systems

The general description of the 32-bit and 64-bit Windows operating systems is about CPU and memory addressing relationships, and now most of the CPU products sold on the market support 64-bit, while memory addressing is about the operating system's 64-bit or 32-bit, with 32-bit systems with a maximum memory addressing space of 2 32 times, approximately 4GB, while the 64-bit system has a maximum addressable space of 2 64, which allows the 32-bit system to support a maximum of 4G memory, while a 64-bit system supports a higher maximum memory. In layman's words, if your system exists below 4GB, you can install 32-bit operating system, you can install 64-bit system, but if your system memory exceeds 4GB, then installing 32-bit operating system will not play a role beyond 4GB, so you should choose 64-bit operating system.

Advantages and disadvantages of 64-bit operating systems

The advantage of using a 64-bit version of Windows is better access to and management of memory, and increased performance for the operating system, and Microsoft's official emphasis on 64-bit systems to enhance overall security performance, such as Kernel patch protection, and support hardware data execution protection and forced driver signature, and the support for 32-bit drivers is canceled, and more applications written for 64-bit operating systems are more practical than the 32-bit version. The relative disadvantage is not so important, such as the driver is incompatible with 32-bit systems, individual applications need to download 64-bit version, and the driver is not as flexible as the 32-bit system, 64-bit operating system must be digitally signed by the developer.

Select the correct operating system

In summary, the difference between 32-bit and 64-bit Windows is clear, and how to choose the version of Windows depends on the actual needs of the user. If the user uses 4GB of memory, then should go to choose 64-bit version, but if it is some time longer computer or old machine, here is still recommended not to use 64-bit system, should be for some of the latest driver does not support the old device or simply for the old device did not develop the corresponding 64-bit driver, In addition, the genuine 64-bit system is priced higher than the genuine 32-bit system, so enterprise users should also be considered from the actual needs.
