The technology attempts to decrease hard drive usage by moving frequently accessed data over to the flash memory. Flash memory can be accessed faster than hard drives and requires less power to operate, thereby allowing laptops to operate faster while also being more power efficient. [3] [4]
Extended memory is located above 1 MB, includes the high memory area, and ends at 16 MB on the Intel 286 and at 4 GB on the Intel 386DX and later. In DOS memory management, extended memory refers to memory above the first megabyte (2 20 bytes) of address space in an IBM PC or compatible with an 80286 or later processor.
Launched by Google in February 2013, the Chromebook Pixel was the high-end machine in the Chromebook family. The laptop has an unusual 3:2 display aspect ratio touch screen featuring what was at its debut the highest pixel density of any laptop, [131] a faster CPU than its predecessors in the Intel Core i5, and an exterior design described by ...
The 1 MB total address space was a result of the 20-bit address space limit imposed on the 8088 CPU. Using the color video buffer space, some third-party utilities could add memory at the top of the 640k conventional memory area, to extend memory up to the base address used by hardware adapters. This could ultimately backfill RAM up to the MDA ...
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 ...

President-elect Donald Trump’s Surgeon General nominee caused a gun accident when she was 13-years-old that left her dad shot dead — a tragedy which inspired her to pursue a career in medicine ...
Later processor families use interconnects such as Hypertransport or QuickPath Interconnect, which lack dedicated memory address signals, so this relationship is less apparent. The 32-bit size of the virtual address is not changed, so regular application software continues to use instructions with 32-bit addresses and (in a flat memory model ...
