to provide you with a little grounding here, home computers purchased at the time this book was written (1999) commonly have 32 MB or 64 MB or sometimes 128 MB of random access memory. (And don’t get too confused just yet—I haven’t mentioned anything about hard drives; I’m talking only about RAM.) That’s 33,554,432 bytes or 67,108,864 bytes or 134,217,728 bytes.
