Detailed explanation of the difference between Windows 32-bit operating system and 64-bit operating system

With the popularity of Windows 7 system, more and more people find that the system on the market begins to be divided into 32-bit and 64-bit, and even processors have 32-bit and 64-bit. The difference between the bits, then what is the difference between 32-bit and 64-bit, which performance is good? Anxia.com tells you.
32-bit and 64-bit Operating system
means: The ability of the CPU to process data at one time is 32-bit or 64-bit. CPUs on the market today are generally 64-bit, but these CPUs are not really 64-bit CPUs. They still retain most of the 32-bit technology, but only some 64-bit improvements. The difference between 32-bit and 64-bit also involves the addressing aspect of memory. The maximum addressing space of a 32-bit system is 2 to the power of 32 = 4294967296 (bit) = 4 (GB), and the maximum addressing of 64-bit systems. The addressing space of the space reaches 2 to the 64th power = 4294967296 (bit) of the 32nd power = the value is greater than 100 million GB. In other words, the 32-bit system's processor only supports up to 4G of memory, while the 64-bit system supports up to 100 million bits of memory.

If the CPUs on the market are all developed on a 64-bit platform, then all the software can't be used now, because most of the software is currently based on 32-bit development. Currently we are talking about 64-bit. The windows7 system only adds some 64-bit addressing functions based on the 32-bit system. In fact, for us, the 64-bit CPU has little meaning for the operating system. After all, most of the memory we use is still 2G. It is also a commonly used software, and the requirements for the operation speed are not large. 64-bit is mainly used in large machinery or large service stations. So 32-bit and 64-bit are faster than 64-bit, but 32-bit is more suitable for us. If you install a 64-bit operating system, you will find that a lot of software can't be used.

The difference between 332 and 64 is that the amount of one-time operation is different. In theory, 64-bit will be twice as fast as 32-bit, and memory addressing is different, but these are meanings for ordinary users. Not big, for the current stage, 32 people will be more suitable for everyone to use.
And in terms of value, 64-bit systems require higher configurations and higher prices, so consider which system you choose from a comprehensive perspective.
