The article talks about how the processor can reference (or address) the memory. In all modern architectures memory is byte-addressable, which means that every byte-sized memory cell has a number (its address), which the CPU uses to identify that cell.
3 Μαρ 2009 · The main advantage of a 64-bit CPU is the ability to have 64-bit pointer types that allow virtual address ranges greater than 4GB in size. On a 32-bit CPU, the pointer size is (typically) 32 bits wide, allowing a pointer to refer to one of 2^32 (4,294,967,296) discrete addresses.
10 Ιουν 2024 · A major difference between 32-bit processors and 64-bit processors is the number of calculations per second they can perform, which affects the speed at which they can complete tasks. 64-bit processors can come in dual-core, quad-core, six-core, andeight-coreversions for home computing.
18 Μαρ 2024 · 64-bit applications can be optimized for 64-bit architectures, taking full advantage of the increased capabilities. In contrast, 32-bit apps may not benefit from these optimizations and could run less efficiently on a 64-bit system.
28 Μαρ 2010 · In a 64bit processor, the processor can (in theory) use 64 bits to address memory, or 2^64 bytes of addressable memory. I believe that amounts to 16 Exo Bytes, which is a huge amount that is almost to the point of counting the amount of molecules in your machine.
25 Ιουλ 2010 · A 64-bit machine should be able to address up to 2 64 addressable units (in architectures designed over the last few decades, addressable units are invariably bytes, a.k.a. octets). If you define a "gigabyte" as 2 30 addressable units, then yes, 2 34 gigabytes would be another way to express the same count.
28 Σεπ 2022 · Given the fact that the system space is shared across all processes, on 32-bit Windows, processes that create large amount of handles (like threads, semaphores, files, etc.) consume system space by kernel objects and can run out of memory even if you have lot of memory available in total.
