     • <- Encoding happens here ->
   • RAM - Short-Term Memory
     • Holds limited amount of information
     • Runs programs
     • Limited capacity
     • Rehearsal is important
   • Storage - Long-Term Memory
     • Unlimited capacity
     • Permanant
     • Able to access and retrieve
   • <- Storage and retrieval both ways ->
   • CPU - Executive Processor
     • Executes functions
     • Moves info
     • Calls programs
     • Directs all activity
     • Monitors all activity
