Direct mapped cache is how to map memory addresses in cache blocks. A worst case scenario for direct mapped cache can be:
When the different blocks present in the main memory map to certain location only in the cache, then it is the case that two different blocks will be mapped to one location at aa time, and both them will be referenced perpetually, this will cause the perpetual swapping. So the memory scheme for the two blocks will fluctuate as the as the two blocks will continuously be going in and out.

Value at Risk (VaR) is used to describe the worst-case scenario over some time horizon with a specific probability. Suppose that an investment on a stock is expected to grow during the year by 10% with SD 35%. Assume a normal model for the change in value. What is the VaR for an investment of $500,000 at 5%?
