The difference between 32-bit and 64-bit operating systems

1. Of course, the 32-bit operating system is installed on a 64-bit computer, and its hardware is just like a "big horse cart": 64-bit performance It will be greatly discounted.

2. Bits and 64 bits represent the maximum number of bits that the CPU can process at a time. Theoretically, the data efficiency processed by the 64-bit system is higher than that of 32-bit, which is equivalent to single-lane and dual-lane driving, and more vehicles can pass in a double-lane unit time.

3. The original design intention is different. 32-bit: The 32-bit operating system is designed for ordinary users.64-bit: Meet the customer needs of mechanical design and analysis, 3D animation, video editing and creation, as well as scientific computing and high-performance computing applications that require a large amount of memory and floating-point performance.

What does the number of digits of the Windows operating system mean?

1. The bit system refers to the data length, instruction length and address length in the machine is binary 32 bits. The 64-bit system refers to the data length, instruction length and address length in the machine are binary 64 bits. The 64-bit system is fast.

2. The number of bits of the operating system means that the operating system has the corresponding characteristics expected by the N-bit CPU, such as larger or even unified addressing space. Perhaps some old codes in the operating system will also be replaced by N-bit new instructions for better performance.

3. That is, the operating number allowed by the operating system is 32 bits. If the operand can reach up to 64 bits, the general register (GPR) that stores the operand must also be 64-bit, and the 64-bit processor also has a 64-bit GPR.

4. This bit refers to the memory addressing space that the operating system can control, that is, the maximum memory limit that the operating system can support. Calculation method: The 16th square, 32nd and 64th square of 2.

5. Some people say that Windows95 is not 32-bit at all. I'm also a little dizzy. 32-bit operating system: Windows NT, 2000, XP should all be counted. Of course, there is also Linux, Vista X86 64-bit operating system: Vista X64 also has XP 64-bit system."Bit" is simply understood as the addressing space of the CPU.

6. The number of system bits refers to the number of operations allowed by the operating system. The larger the number of digits, the greater the processing and running speed.

How to check the operating system bits?

1. Execute 'unAme -a' command The highlighted i686 (or sometimes i386) indicates that the operating system is 32-bit, but if it shows x86_64, it means that the operating system is 64-bit.

2. You can also right-click the computer icon on the desktop, open the property interface, and view the digits of the operating system in the system-system type. If "Magic Cube Computer Master" is installed on the computer, you can also check the digits of the operation. Open "Magic Cube Computer Master", open the radar-native information, and you can see the operating system bits.

3. Method 1: Right-click on this computer (My Computer, Computer) and click Properties. In viewing the basic information about the computer - system type: specific digits will be displayed, such as the 64-bit operating system shown in the figure.
