What is Storage: Definition and 256 Discussions

CONFIG.SYS is the primary configuration file for the DOS and OS/2 operating systems. It is a special ASCII text file that contains user-accessible setup or configuration directives evaluated by the operating system's DOS BIOS (typically residing in IBMBIO.COM or IO.SYS) during boot. CONFIG.SYS was introduced with DOS 2.0.

    Neodymium Magnets as energy storage?

    Neodymium magnets have an energy capacity of 512 kJ/m3 or 0,512 MJ / cubic liters. That's equivalent to 0.0085 kWh or 8.5 Wh each 1 dm^3. You could recharge an mp3 player for 34 hours, and then you'd have to throw away your magnet. That's still 468 times less than the capacity of a Lead-acid...

    What is the total memory storage of the human genome?

    My answer is that the 3Gigabits of base 4 memory in the human genome is equivalent to 750MB of binary standardised to 8 bits/byte. Once I have taken into account that there are two copies, evolutionary junk and repeated or copied areas, I am getting an estimate of around 30MB.
