ปี Amount of RAM (GB) in a typical computer About 4TB in 2025
64-Bit Architectures IA-64 AMD 64, EM64T Or X86-64 True 64bit CPU Hybrid 32/64 bit CPU
A hybrid 32/64 bit system Has the benefits of a 64-bit programs Can also run older 32-bit programs 32-Bit programs will not benefit from the 64- bit architecture Architecture not as clean as true 64-bit systems
