This article shows you how to know whether your windows system is 32-bit or 64-bit. The content is concise and easy to understand, which will definitely brighten your eyes. I hope you can get something through the detailed introduction of this article.

Step 1: enter winver (system version number command) in start > run.

Step 2: see the open system version information. If what you open is similar to the image below, then your system is 32-bit.

Step 3: if your system is 64-bit, "x64 edition" will be clearly marked.

Through the two comparative pictures above, you should know how many bits your system is, work smoothly and everything goes well.

Another way to check it: C:\ windows\ system32 (there is a difference) c:\ windows\ system64

Difference: online articles

32-bit and 64-bit operating systems refer to whether the computer operation mode is 32-bit or 64-bit, because in cpu, it is calculated in binary, 32-bit is binary in length, 32-bit is 64-bit, and binary is 64. So 64-bit cpu can install 32-bit, 64-bit operating systems, but 32-bit operating systems can only install 32-bit operating systems!

The operating system is just a platform between hardware and application software.

32-bit cpu design for 32-bit operating systems.

64-bit cpu design for 64-bit operating systems.

Our cpu has gone from 8-bit and 16-bit to 32-bit and 64-bit.

Cpu treats "data" and "instructions" differently when dealing with calculations.

An 8-bit cpu can only process an 8-bit "data" or an 8-bit "instruction" at a time. For example, '00001101'.

Another example: "+ 1" this operation, you have to instruct cpu to do "+", and then input "1" data to cpu.

The 8-bit cpu has the advantages of simple design and fast processing speed.

The disadvantage is that the software design is complex and tedious. It is not conducive to the development of computers.

Later, with the introduction of 16-bit cpu, we can process two bytes (16 bits) of data at a time, such as the "plus 1" command. "add" is an instruction that takes up 8 bits, and we can store the remaining 8 bits.

32-bit cpu is even more convenient, so we can process commands like a=a+b one at a time.

Advantages: simplifies the complexity of software design

Disadvantages: the hardware design is more complex and the computing speed decreases.

Generally speaking, 32-bit cpu is the most rational cpu for us, which is enough for software development.

But the 32 th power of 2 = 4294967296bit = 4G

It is obvious that 32-bit cpu has only about 4G memory addressing space, which is not enough for some servers. If we need more memory addressing space, we need to upgrade cpu. That's how 64-bit cpu was born. Do the math about the memory address space of 64-bit cpu.

2 to the power of 64 (theoretically).

But now amd and inter's 64-bit cpu is not really 64cpu, only some 64-bit improvements, such as 64-bit memory addressing and so on.

If all of them are 64-bit, then all the software on the market will be eliminated and cannot be used ~ hehe, imagine what it will be like.

The 64-bit operating system is designed for 64-bit cpu, with some 64-bit instructions added, but is still compatible with 32. A 64-bit system doesn't make much sense to us ordinary users.

The above is how to know whether your windows system is 32-bit or 64-bit. Have you learned any knowledge or skills? If you want to learn more skills or enrich your knowledge reserve, you are welcome to follow the industry information channel.
