Most people don't know the difference between a 32-bit and a 64-bit operating system. With the release of Windows 7, the question is raised again on whether you should install the 32-bit version of the operating system or move up to 64-bit. (See the tutorial: How to figure out if you have a 32 or 64-bit Operating System on your PC or Laptop?) For the high end users, who want to squeeze every drop of his computer's processing power, knowing the difference between a 32-bit and a 64-bit processor and an operating system is important. And if you are still stuck with a 32-bit Operating System, an upgrade to a 64-bit Operating System is a must.
The most basic difference is the amount of memory (RAM) that a 32-bit Operating System can make use of. If you want to use 4 GB of RAM with a 32-bit system - it is not going to work. Even if you install 4 GB modules, due to technical reasons, the Windows Operating System will still be able to detect and make use of a maximum of 3.5 GB.
Besides more RAM, more advantages of the Windows 64-bit are listed below:
1. Better performance for 64-bit software: If a 64-bit version of your favorite application is available and you have a 64-bit Operating System, go for that. The 64-bit software would be faster in processing speeds.
2. Some programs such as data encryption software can benefit greatly from 64-bit registers (if the software is 64-bit compiled) and effectively execute 3 to 5 times faster on 64-bit than on 32-bit.
3. A 64-bit Operating System can run 32-bit applications, there is backward compatibility, but 32-bit Operating System cannot run 64-bit applications.4. If you have a 64-bit processor, you are safe for the near future because 64-bit is the trend. 64-bit will replace 32-bit one day soon.
A 64-bit PC will be supplied with a large hard drive, generally over 250GB in size and with Windows and other applications pre-installed. The hard drive is generally pre-configured either as one large partition. But if you upgrade from XP for other earlier operating systems, your system partition might be insufficient for the Windows 7 64-bit installation. There is no easy way of changing the sizes of these partitions from within Windows, using the supplied tools. So a reliable third party 64-bit partition manager software is the only way out. The famous and cost-efficient EaseUS Partition Master is the best recommendation for 64-bit partition manager software.
