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 ]
Apache OpenOffice 4.1.0 was released for x86 and X86-64 versions of Microsoft Windows XP or later, Linux (32-bit and 64-bit), and Mac OS X 10.4 "Tiger" or later. [ 67 ]
Many 32-bit computers have 32 physical address bits and are thus limited to 4 GiB (2 32 words) of memory. [3] [4] 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, [5]: 445 which allows addressing up to 64 GiB (2 36 words) of memory.
The operating systems the office suites were designed to run on without emulation; for the given office suite/OS combination, there are five possibilities: . No indicates that it does not exist or was never released.
Apple stopped developing 32-bit Mac OS versions in 2018 delivering macOS Mojave only as a 64-bit operating system. [11] The end-of-life for Windows 10 has been set to 2025 on the desktop which is related to the latest upgrades from old systems like Windows 7 & Windows 8 in January 2020 as some of those system ran on old computers built on the ...
This is a list of free and open-source software (FOSS) packages, computer software licensed under free software licenses and open-source licenses.Software that fits the Free Software Definition may be more appropriately called free software; the GNU project in particular objects to their works being referred to as open-source.

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 [16] 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.
The Intel 8080 used by these computers was an 8-bit processor, with 16-bit address space, which allowed it access up to 64 KB of memory; .COM executables used with CP/M have a maximum size of 64 KB due to this, as do those used by DOS operating systems for 16-bit microprocessors.
