Windows 11 running in safe mode. Microsoft Windows' safe mode (for 7/Vista [1] /XP [2] /2000/ME/98/95 [citation needed]) is accessed by pressing the F8 key as the operating system boots. [3] Also, in a multi-boot environment with multiple versions of Windows installed side by side, the F8 key can be pressed at the OS selector prompt to get to ...
In DOS memory management, the upper memory area (UMA) is the memory between the addresses of 640 KB and 1024 KB (0xA0000–0xFFFFF) in an IBM PC or compatible. IBM reserved the uppermost 384 KB of the 8088 CPU 's 1024 KB address space for BIOS ROM , Video BIOS , Option ROMs , video RAM, RAM on peripherals, memory-mapped I/O , and obsoleted ROM ...
Automatic memory management in the form of garbage collection is the most common technique for preventing some of the memory safety problems, since it prevents common memory safety errors like use-after-free for all data allocated within the language runtime. [11]
In computing, protected mode, also called protected virtual address mode, [1] is an operational mode of x86-compatible central processing units (CPUs). It allows system software to use features such as segmentation, virtual memory, paging and safe multi-tasking designed to increase an operating system's control over application software.
Three segments in real mode memory (click on image to enlarge). There is an overlap between segment 2 and segment 3; the bytes in the turquoise area can be used from both segment selectors. In real mode or V86 mode, the size of a segment can range from 1 byte up to 65,536 bytes (using 16-bit offsets).

Hibernation (also known as suspend to disk, or Safe Sleep on Macintosh computers [1]) in computing is powering down a computer while retaining its state.When hibernation begins, the computer saves the contents of its random access memory (RAM) to a hard disk or other non-volatile storage.
The first DPMI specification drafts were published in 1989 by Microsoft's Ralph Lipe. [4] [1] While based on a prototypical version of DPMI for Windows 3.0 in 386 enhanced mode, several features of this implementation were removed from the official specification, including a feature named MS-DOS Extensions [5] or DOS API translation that had been proposed by Ralph Lipe in the original drafts.
