What's the difference between a 32-bit system and a 64-bit system

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.

The differences are as follows: the maximum running memory supported is different: the maximum support for 32-bit systems only 4G (generally, only about 25G can be used), while the 64-bit operating system can support 128G or even larger.

The computing power is different: 64-bit systems are theoretically twice as fast as 32-bit systems, and their memory addressing is also different. The maximum running memory supported is different: 32-bit computers can only support 4G at most (generally, only about 25G), while 64-bit computers can support 128G or even larger.

What is the difference between a computer 64-bit system and a 32-bit system?

The supported memory is different. The 32-bit operating system supports up to 4G of memory, but the 64-bit system supports 4G, 8G, 16G, 32G, 64G, 128G, 256G, etc.

The supported memory is different (different addressing ability). The maximum addressing space of the 32-bit system is about the 32nd power of 2 = 4294967296 (bit) = 4 (GB); and the maximum addressing space of the 64-bit system is the 64th power of 2 = 4294967296 (b The 32nd square of it), the value is greater than 100 million GB.

The concepts and differences between computer 64-bit and 32-bit systems are as follows: 64bit CPU has a largerAddress capability, up to 16GB of memory, while 32bit only supports 4G memory. 64-bit CPU can extract 64-bit data at a time, which is twice as good as 32-bit, and theoretically, the performance will be improved by 1 times. But this is based on the 64bit operating system and 64bit software.

bit and 64-bit mainly refer to the ability of the CPU to process data at a time. 32-bit is 32bit, that is, it can process 4 bytes of data at a time; 64-bit is 64bit, that is, it can process 8 bytes at a time.

The computing speed is different. Theoretically speaking, the 64-bit system runs twice as fast as the 32-bit system; the 64-bit system can be said to be a fundamental change compared with the 32-bit system.

The difference between a bit system and a 64-bit system.The processing mechanism of the CPU processor is different. Relatively speaking, 64-bit optimizes the efficiency of computer processor processing information in RAM (random access memory) than 32-bit, which is more efficient and faster. The capacity of the effective memory that the operating system can support is different.

The difference between 64-bit and 32-bit

1. The original design intention is different 32-bit: The 32-bit operation 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.

2. The supported memory is different. The 32-bit operating system supports up to 4G of memory, but the 64-bit system can support 4G, 8G, 16G, 32G, 64G, 128G, 256G, etc.

3. Different computing power: 64-bit systems are theoretically twice as fast as 32-bit systems, and their memory addressing is also different.The maximum running memory supported is different: 32-bit computers can only support 4G at most (generally, only about 25G), while 64-bit computers can support 128G or even larger.

4. Different CPU requirements. CPUs are divided into 32-bit and 64-bit. 32-bit CPUs can only install 32-bit systems, while 64-bit CPUs can install both 32-bit systems and 64-bit systems.
