Because of a limitation of DOS, 640 kilobytes
was the maximum that any program could use directly, and the 8086 and 8088 processors contained in the PC could not address more than I megabyte of -memory in any case.
Both are GSM standards that target data transmission at speeds greater than 115 kilobytes
But the KDDI Java service is capable of downloading up to 50 kilobytes
of software, compared with 10 kilobytes
EXE followed by the number of kilobytes
you want for the maximum cache size, followed by the number of kilobytes
you want in the cache at a minimum.
A typical scanned page, at a resolution of 200 dots per inch, takes up about 20 kilobytes
Even if your PC is equipped with 1 megabyte of memory, the amount between 640 kilobytes
and 1 megabyte is not normally available for running programs, as this 384 kilobytes
is reserved for peripherals.
Bottom line: Look for Cache memory of between 128 and 256 kilobytes
That's because the original IBM personal computer was designed with the idea that 640 kilobytes
of random-access memory was all anyone would and should ever need.
The LaserCard optical memory card is capable of recording and storing up to 2,800 kilobytes
