Memory
Values in the Memory field cannot be changed and 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
Base Memory is typically 640 KB. It is also referred to as conventional memory.
The DOS operating system and conventional applications utilize this type of
memory.
Extended Memory
Extended Memory is 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; which is often called High memory, DOS may load
Terminate-and-Stay-Resident (TSR) programs, such as device drivers, to free as
much conventional memory as possible for applications. Lines in your
CONFIG.SYS files that begin with LOADHIGH will load programs into high
memory.
Total Memory
System total memory is the sum of base memory, extended memory, and other
memory.
