Here’s why there isn’t a 128-bit operating system. There are mainly 32-bit and 64-bit operating systems, but what about 128-bit operating systems? So if you want to learn why there aren’t 128-bit operating systems, then you’re in the right place. Keep reading! What About Bits and Operating Systems? Currently, there are 32-bit and 64-bit processors, operating systems, and programs. Before these existed, programmers worked with 8-bit and 16-bit systems. Therefore, it would be logical to assume that new devices and programs with higher bit depth will appear along with the progression of technical development. The logical next step should be 128-bits. But does that make sense? Let’s figure it out. The digit capacity in computer science is the number of bits that a device can simultaneously process. There is: Processor’s bit capacity—the capacity of its machine word. Data bus capacity—the operating system’s capacity. Capacity of programs and applications. All these are different concepts overlap and may partially depend on each other. At the lowest level is the processor capacity. Why Are There No 128-Bit Operating Systems? (3 Steps) We have to consider several issues: Challenges related to bit depth. Processor’s bit capacity and the bit version of OS and how they are related. Growth of bit depth occurred historically and why it has stopped at the moment. Increasing the system capacity over 64 at present may be of interest only for a narrow range of applied problems. With the growth of the bit depth, the calculation accuracy also increases. The 128-bit (or higher) architecture is useful for mathematically intensive operations such as graphics, cryptography, and complex system modeling, but not for operating systems. Based on the preceding conversation, we can conclude that a system with a 64-bit processor is now sufficient for the bulk of users. The 64-bit system offers enough computer performance capacity for most professional applications such as: Mathematics Physics Geodesy Cartography Cryptography Databases 64- or even 32-bits
