Weak current College】 【avoid mistakes on the correct understanding of the 64-bit operating systems and applications.

<br> As the era of development and hardware advances, now 64-bit is increasingly becoming PC development trend, win7s Server version WindowsServer2008R2 has only 64-bit version. But the outside world on 64-bit, in fact, there are still many .misconceptions: <br> <br> 1.64 bit better than the 32-bit <br> <br> In fact, this was a different issue, namely the General Internet browsing, Office and normal game, the 32-bit system to cope with .more than adequate. But for some users who need large memory, 64-bit will be the better choice. In addition, there is no doubt that the 64-bit is, indeed, trends and fashion. <br> <br> 2.64 bit .compatibility as 32-bit <br> <br> Many people mistakenly believe that some 32-bit program will not run on 64-bit systems, in fact, 64-bit systems will provide a name for the ProgramFiles (x86) folder, which .is 32-bit applications. But there is a built-in Windows764-bit to 32-bit and 64-bit versions of IE8. At the same time, the 32-bit programs in the taskbar and Explorer will display as XX.EXE * .32. Or even, in some cases, a 64-bit program compatibility also better than 32 bits. For example, the impression is not in the earlier AION in 32-bit win7s running, but the 64-bit down without problems. <br .> <br> 3.64 bit software performance higher than 32-bit <br> <br> This is also known for 64-bit in the most vulnerable of misunderstanding. In response to this issue, Adobe specialist company JohnNack in its blog issued explained that .he first invoked the Apple Developer documentation in the original: <br> <br> "For most developers, be they code packaged as a 64-bit program and does not provide any advantages. Unless the program requires more than 4 GB of memory, .or packaged into a 64-bit program not only will not create performance boost, but will result in performance degradation. "<br> <br> Subsequently, John once again refer to Apple's original 's64-bitTransitionGuide explained: <br> <br .> "Rumor: native support for 64-bit programs run faster <br> <br> Fact: some 64-bit programs on 64-bit Intel architecture because cache pressure run more slowly <br> <br> On a 64-bit Intel .architecture machines, 64-bit programs as native support for 64-bit code relationships may cause some performance, but because of the increased pressure of the cache so that upgrading is often enough to make up for the cache pressure brought about by the loss of performance ..
