On DOS systems, conventional memory refers to the portion of memory that is available to standard DOS programs. DOS systems have an address space of 1MB (megabyte), but the top 384K (called high memory) are reserved for system use. This leaves 640K of conventional memory. Everything above 1MB is either extended or expanded memory.

The term memory identifies data storage that comes in the form of chips, and the word storage is used for memory that exists on tapes or disks. Moreover, the term memory is usually used as shorthand for physical memory, which refers to the actual chips capable of holding data. Some computers also use virtual memory, which expands physical memory onto a hard disk. Conventional Memory is the first 640K of memory.

The reader has 1MB of battery-backed dynamic RAM. The first 640K is conventional memory and is virtually the same as that of a PC. You can use this memory to run applications.

Relating to the DOS memory map, conventional memory is the memory addresses between 0 and 640K. MS Dos requires the Operating System, Vector Table, and all programs to load and run in this small amount of memory. While trying to maintain backwards compatibility with the older OS, newer programs and Operating Systems have had to deal with what is termed the 640K barrier.

The first 640K of memory on MS-DOS computers. If you use no memory managers, this is the only memory that programs can use. See also expanded memory, extended memory (EMS), extended memory blocks, high memory area (HMA), memory manager, upper memory blocks (UMBs).

DOS memory where programs run - lower 640kBytes - sometimes considered as first 1MByte

Memory below 640 KB, sometimes called base memory. It is generally where the operating system and applications are loaded. It is usually referred to as RAM (Random Access Memory).

Memory located in the first 640K block.

DOS memory, sometimes referred to as conventional memory, refers to the memory-addressing scheme used in the original IBM and compatible PCs. These came with only one operating system, Disk Operating System, and this operating system had to be designed to work with the PC's microprocessor, the Intel 8088. Because of 8088 engineering limitations, storage or memory addresses were limited to a maximum of one megabyte. (Later, of course, PC's came with 2, 4, 8, and today's common 256 and 512 megabytes of RAM.) At the time, however, one megabyte was considered a rather large amount of memory to be able to access.

The first 640 KB of RAM. Conventional memory is found in all computers.

The most basic type of memory in a computer used to run programs designed for use with DOS. conventional memory is limited to 640K. (DOS and Windows)

The region between 0K and 640K used by DOS for running all programs.

On IBM PC and compatible computers, the first 640 kilobytes of memory (RAM).

The memory space between zero and 1024KB that is directly addressable by the 8086 and 8088 CPU= s or by 80286, 80386 and 80486 CPU= s operating in real mode. DOS and it= s applications are designed to use only the lower 640KB of this conventional memory space. The remaining 384KB is used for video RAM, the BIOS and/or RAM for hardware cards.

(Memoire Conventionnelle) : In a PC DOS system, part of storage between 0 and 640 KB, in which most DOS native applications work. Synonymous of "Base Memory".

In an IBM PC or compatible computer, up to the first 640K of memory in your computer. MS-DOS by default uses only this memory to run programs.

Refers to the fist 640 KB of RAM, particularly within the context of MS-DOS programs. There are programs which can modify this standard.

the first 0-640KB of memory referred to as "Base Memory."

Conventional memory is the first 640 kilobytes of an IBM PC's memory.
