Memory

1. RAM

   • Random access Memory
     • Allows storage of data and information such as OS's
     • RAM advantages you can "write" to ram at any time, and then erase the ram at any time and "rewrite" over it.
     • It has a disadvantage in that you need to constantly supply it with power or it will lose its information.
   • Is volatile, loses its state when power supply is lost

2. ROM

   • Read Only Memory
     • ROM advantage is that (generally) once it is "written" to, it will be there forever.
     • It does not require constant source of electricity.
     • cannot be altered

3. Flash Memory

   • Faster read and write compared to traditional hard disk drives.
   • Currently costs a lot more per gigabyte than traditional hard drives for large storage capacities.
   • Less prone to damage.
