What is APES? AP Environmental Science (APES) is a year-long course that is the equivalent to a one semester college level Environmental Science course. Students will be expected to take the AP Environmental Science test in May 2016.
RAID is basically a group of disks, usually with one or both characteristics of parity and striping. Parity is redundancy of your blocks of data on the disks; striping allows the individual drive speeds and feeds to add up, giving you more performance than a single disk could provide.
RAID is short for redundant array of independent disks. Originally, the term RAID was defined as redundant array of inexpensive disks, but now it usually refers to a redundant array of independent disks. RAID storage uses multiple disks in order to provide fault tolerance, to improve overall performance, and to increase storage capacity in a system.
