Page Fault means the Data or Instruction needed for execution
is not present onto the Main memory.
Page thrashing refer to the condition where the Contents of
the Main Memory(DRAM) is swapped very frequently becouse the
part of the program in the main memory does not contain the
instruction to be executed thus those instruction are loaded
from the storage to the Main memory. This process Has a high
overhead.
