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]
Intel Trusted Execution Technology (Intel TXT, formerly known as LaGrande Technology) is a computer hardware technology of which the primary goals are: Attestation of the authenticity of a platform and its operating system. Assuring that an authentic operating system starts in a trusted environment, which can then be considered trusted.
The barrier is not present with a 64-bit processor and 64-bit operating system, or with certain x86 hardware and an operating system such as Linux or certain versions of Windows Server and macOS that allow use of Physical Address Extension (PAE) mode on x86 to access more than 4 GiB of RAM.
Ubuntu Linux stopped delivering a 32-bit variant in 2019. [9] Nvidia stopped to develop 32-bit drivers in 2018 and deliver updates after January 2019. [10] 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 ...
In computing, a memory barrier, also known as a membar, memory fence or fence instruction, is a type of barrier instruction that causes a central processing unit (CPU) or compiler to enforce an ordering constraint on memory operations issued before and after the barrier instruction. This typically means that operations issued prior to the ...
A light-weight Linux distribution is a Linux distribution that uses lower memory and processor-speed requirements than a more "feature-rich" Linux distribution. The lower demands on hardware ideally result in a more responsive machine , and allow devices with fewer system resources (e.g. older or embedded hardware ) to be used productively.
