'''Invalid''' - Line data is not valid.
For efficiency this core will now read the stored cache value instead of reading the same value from memory when possible this will save time and processing power.
core 2 also starts to read values but from value 2 from the main memory.
Lastly. core 2 notifies core 1 of the changes in values. which marks the cache line as '''invalid'''.
