The 2 GB limit refers to a physical memory barrier for a process running on a 32-bit operating system, which can only use a maximum of 2 GB of memory. [1] The problem mainly affects 32-bit versions of operating systems like Microsoft Windows and Linux, although some variants of the latter can overcome this barrier. [2]
These processors have 8-bit CPUs with 8-bit data and 16-bit addressing. The memory on these CPUs is addressable at the byte level. This leads to a memory addressable limit of 2 16 × 1 byte = 65,536 bytes or 64 kilobytes. 16 address bits, 20 address pins: 8086, 8088, 80186 & 80188

v. t. e. In computer architecture, 32-bit computing refers to computer systems with a processor, memory, and other major system components that operate on data in 32- bit units. [1] [2] Compared to smaller bit widths, 32-bit computers can perform large calculations more efficiently and process more data per clock cycle.
However, "client" versions of 32-bit Windows (Windows XP SP2 and later, Windows Vista, Windows 7) limit physical address space to the first 4 GB for driver compatibility even though these versions do run in PAE mode if NX support is enabled. Windows 8 and later releases will only run on processors which support PAE, in addition to NX and SSE2.
Physical address limits. Many 32-bit computers have 32 physical address bits and are thus limited to 4 GiB (2 32 words) of memory. x86 processors prior to the Pentium Pro have 32 or fewer physical address bits; however, most x86 processors since the Pentium Pro, which was first sold in 1995, have the Physical Address Extension (PAE) mechanism,: 445 which allows addressing up to 64 GiB (2 36 ...
At the time of launch, Microsoft deemed Windows 7 (with Service Pack 1) and Windows 8.1 users eligible to upgrade to Windows 10 free of charge, so long as the upgrade took place within one year of Windows 10's initial release date. Windows RT and the respective Enterprise editions of Windows 7, 8, and 8.1 were excluded from this offer.
