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
amount of memory that is really available is certainly less than 4GB, which is the 3.xxG shown in the system properties that we see.
However, the 64-bit CPU has changed a lot, the 64-bit CPU's maximum addressing space is 2 of the 64
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.

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 sup
32-bit Linux supports up to 4 GB of memory, and 64-bit Linux supports up to TB level. (In fact, the maximum supported content is not related to the type of the operating system, but to the number of operating systems and the number of CPUs .) DOS is 16 bits, so the maximum memory supported by DOS is 64 MB (the 16-power
The 32-bit 64-bit operating system supports memory differences. Why does Win7 only display 4 GB memory ?, Win74g

To use a 64-bit version of Windows Vista, you must meet the following two conditions:1. The computer must have a 64-bit processor;2. A 64-bit device driver must be provided for devices
The difference between 32-bit systems and 64-bit systems has the following four points:
First, the CPU requirements are different
