Memory
You cannot change any values in the Memory fields; they are only for your information.
The fields show the total installed random access memory (RAM) and amounts
allocated to base memory, extended memory, and other (high) memory. RAM is
counted in kilobytes (KB: approximately one thousand bytes) and megabytes (MB:
approximately one million bytes).
RAM is the computer's working memory, where the computer stores programs and data
currently being used, so they are accessible to the CPU. Modern personal computers
may contain up to 64 MB, 128 MB, or more.
Base Memory
Typically 640 KB. Also called conventional memory. The DOS operating system
and conventional applications use this area.
Extended Memory
Above the 1-MB boundary. Early IBM personal computers could not use memory
above 1 MB, but current PCs and their software can use extended memory.
Other Memory
Between 640 KB and 1 MB; often called High memory. DOS may load terminate-
and-stay-resident (TSR) programs, such as device drivers, in this area, to free as
much conventional memory as possible for applications. Lines in your
CONFIG.SYS file that start with LOADHIGH load programs into high memory.
Total Memory
System total memory is the sum of base memory, extended memory, and other
memory.
