simple definitions are: 
QA:assurance for process control.here we r going to follow certain quality standards and strive for process improvement.we r not going to deal with product.the intension is to follow good quality standards.if we follow these automatically we are going to produce better/best product. 
 
that means we are following prevention mechanism where we are going to follow the proverb"prevention is better than cure".that means instead not following the standards and releasing a worst product and then following its better to follow earlier. 
 
QC:control of the product.after finding defects we are going to rectify. 
it is quite reverse to QA.we r curing the defects. 
best examples for these QA ,QC are traffic rules.
