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]
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.
Opera GX is a gaming-oriented alternative to Opera. The browser was announced on 21 May 2019 and released in early access for Windows on 11 June 2019, during E3 2019. The macOS version was released in December of the same year. [94] [95] [60] Opera GX adds features geared toward gamers and other audiences, with the regular Opera browser ...
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.
In January 2018, Opera launched Opera News, an AI-driven news app dedicated to African users. It reached more than a million downloads in less than a month. [41] In April, the company released a new mobile browser called Opera Touch. It includes an innovative user interface focused on ease of use and one-handed browsing. [42]

Memory bus (interface) width: Each DDR, DDR2, or DDR3 memory interface is 64 bits wide. Those 64 bits are sometimes referred to as a "line." Those 64 bits are sometimes referred to as a "line." Number of interfaces : Modern personal computers typically use two memory interfaces ( dual-channel mode) for an effective 128-bit bus width.
