Upgrading an existing system can sometimes be a wise thing to do, but sometimes the upgrade costs more than the system is worth. Also, if existing components are old, they might not be compatible with components you want to use for the upgrade. A friend, Renata, asks your advice about several upgrades she is considering. Answer these questions:
Renata has a four-year-old desktop computer that has a Core2 Duo processor and 2 GB of memory. It does not have an eSATA port.

The CPU accounts for 50% of total server power in a server, the memory system accounts for 30%, the disc accounts for 10%, and other components account for the remaining 10%.
You have $500 to spend on upgrading your server to make it more energy efficient.
You intend to replace your memory module with a new memory module or your hard drive with a new hard disc.
With the money, you may either buy a new memory module that uses 40% less power than your previous memory module or a new disc that uses 40% less power than your old disc.
Which would you buy if you were solely concerned with lowering your server's power consumption?
