详细解说Win 7系统32位、64位不同的地方

认证系统分享：详细解说关于Win 7系统32位、64位不同的地方
       Windows 7从另一种角度上来说，包含两类大版本，一个是32位，另一个则是64位。64位系统就一定强过32位吗？你是否需要64位Windows 7？32位系统和64位系统有什么区别？
       在内存与CPU上的区别
       首先，相信选择64位Windows 7的网友中很有大比例是内存大于或等于4GB的。在32位Windows 7下，可能会显示内存可使用3.25G，这让很多网友感到不安。没错，可寻址的内存空间确实是32位Windows 7和64位Windows 7最为显著的特点。

       32位的CPU（准确的说是运行在32位模式下的CPU）只能寻址最大4GB的内存，受制于此，32位的操作系统也只能识别最大4GB的内存，由于在系统中，

除了内存之外，还有很多存储设备，因此，真正可以利用的内存空间肯定小于4GB，也就是我们看到的系统属性中显示的3.xxG。

       但64位CPU则有了很大改变，64位CPU的最大寻址空间为2的64次方bytes，计算后其可寻址空间达到了惊人的16TB（treabytes），即16384GB。当然，这只是理论，从实际应用上，Windows 7 64bit的各版本分别为8GB-192GB，其中，家庭普通版能支持8GB内存，家庭高级版能支持16GB内存，而64位的Windows 7专业版、企业版和旗舰版最高可支持192GB内存。
       也就是说，内存大于等于4GB的用户，由于受到32位硬件限制，因此，不能最大化的利用硬件资源，这就很有必要安装64位操作系统以最大化利用资源。
       需要注意的是，64位系统需要64位CPU的支持，在安装64位Windows 7前请先确认你的CPU是否支持64位，一般而言，2006年之后购买的CPU均支持64位模式。

       如果仅考虑这点，对于内存小于4GB的用户，32位Windows 7更适合大家使用，因为64位版本会占用更多的系统内存资源，起的作用适得其反了。
