Difference between DOS and HIMEM.SYS

DOS vs. HIMEM.SYS

DOS is a family of disk operating systems. HIMEM.SYS is a DOS device driver which allows DOS programs to store data in extended memory via the Extended Memory Specification (XMS).

Similarities between DOS and HIMEM.SYS

DOS and HIMEM.SYS have 14 things in common (in Unionpedia): CONFIG.SYS, Conventional memory, Device driver, DOS, DR-DOS, EMM386, Expanded memory, Extended memory, FreeDOS, High memory area, Kernel (operating system), Microsoft Windows, Upper memory area, Windows 9x.

CONFIG.SYS

CONFIG.SYS is the primary configuration file for the DOS and OS/2 operating systems.

EMM386

The name EMM386 was used for the expanded memory managers of both Microsoft's MS-DOS and Digital Research's DR-DOS, which created expanded memory using extended memory on Intel 80386 CPUs.

Expanded memory

In DOS memory management, expanded memory is a system of bank switching that provided additional memory to DOS programs beyond the limit of conventional memory (640 KB).

Windows 9x

Windows 9x is a generic term referring to a series of Microsoft Windows computer operating systems produced from 1995 to 2000, which were based on the Windows 95 kernel and its underlying foundation of MS-DOS, both of which were updated in subsequent versions.
