The processor architecture determines the bit rate of data processing and the address that the processor can process. The main difference between 32-bit and 64-bit architectures is the number of bits used to represent addresses and data in computer memory.
The 32-bit architecture means that the processor can simultaneously process 32-bit addresses and data. This means that the processor can address up to 2^32 (about 4.3 billion) unique places in memory. Such an architecture limits the amount of RAM that the processor can use efficiently.
The 64-bit architecture allows the processor to process 64-bit addresses and data. This allows the processor to address and work with large amounts of memory, as it can address up to 2^64 unique places in memory, which greatly exceeds the needs of most users.
However, for full use of the 64-bit architecture, support for both the hardware and software parts of the system is required. This means that the operating system, drivers and applications must also be specifically designed and optimized to work with a 64-bit architecture. Most modern computers support a 64-bit architecture, which allows you to effectively use larger amounts of memory and work with more powerful programs and operating systems.
Why has the 64-bit architecture gained popularity recently, and 32-bit vice versa?
- Larger memory capacity: A 64-bit architecture can address significantly larger memory capacities than a 32-bit architecture. This is especially important for modern computers, which require more RAM to run large programs, virtual environments, databases, etc.
- Increased performance: 64-bit operating systems and applications can use computer resources more efficiently, such as processors with higher bits and memory. They are able to process larger amounts of data at the same time, leading to improved performance and performance.
- Support for more powerful applications: Many modern applications and games require more memory and more powerful processors. The 64-bit architecture allows you to work effectively with such applications, increasing their performance and providing greater functionality.
- Compatibility with modern technologies: Many new technologies and standards such as high-resolution images, 4 K video, encryption, virtualization, etc. require more memory and computing resources The 64-bit architecture provides a powerful platform to support these modern technologies.
With the progress and development of technology, the 32-bit architecture loses its relevance because it is limited in memory and performance. Therefore, the 64-bit architecture is becoming more and more popular and is widely used in modern computers and operating systems. For example, the popular operating system Ubuntu (based on Linux) no longer supports 32-bit architectures as it did before. For boot Ubuntuprovides 64-bit ISO images.
