what is the diffrence between win7 32 bi and 64 bit
doing the math......32 bits :0
1. RAM - With a 32-bit operating system, there's the 4 GB of system RAM. Even if you install additional RAM, it will go to waste as the 32-bit operating system will not be able to access it. With a 64-bit OS, there's support memory far in excess of 4 GB. There are 64-bit versions of the Windows that can handle 192 GB of RAM, tho Home is limited to 16 if memory serves (pun intended). The actual
2. Security - All device drivers for 64-bit versions of Windows must be digitally signed. Attempt to install incompatible or unsigned device drivers will fail. This feature meansl 64-bit operating systems have better security than their 32-bit counterparts. 64 bit systems also provide kernel patch protection DEP protocols and other goodies to keep your system safe.
3. Performance - The bits refer to how big the chunks of data being transferred are. A 64 bit system can lift data off storage devices 64 bits at a time. In 32 bit systems, only half as much can be sent at one time. Having a 64 bit OS doesn’t automatically make all applications faster because much of today’s software is written and optimized for a 32 bit era. You’ll need software specifically optimised for 64 bit processing to take advantage of any speed improvements. If ya just went grocery shopping and have 12 bags in the car, you'll generally get them inside faster carrying 2 bags at a time.....maybe not twice as fast, but faster.
4. Compatibility - Running newer 64 bit programs will run faster on a 64 bit windows system than in compatibility mode on a 32 bit system.
