I only understand in simple words that there are Three types of Pipelining Hazards
1)Resource Hazards
this type of hazards occur when the two instructions require the same resource at same time.
2)Data hazards
suppose there are two Registers or operands values A and B to be used
like Add A,B
Sub A,B
then during the timing signals it maybe possible that two instructions require it both simultaneously at same time then this is data hazards
3)Control hazards
it occurs when the two branching condintion if else both are required at the same time
Now there are three types of Data hazards ie RAW WAW WAR
please explain
