  3. 3. Introduction of a processor Before discussing about i3 processor, let a small introduction of processor. A processor is the logic circuitry that responds to and processes the basic instructions that drive a computer. The term processor has generally replaced the term central processing unit (CPU). The processor in a personal computer or embedded in small devices is often called a microprocessor. 3
  4. 4. Brief introduction about i3 processor The only question I have is if theres any advantage to using a Core i3 over a Core2Duo. The Core i3 is a 3.2 GHz dual core chip, and its quite a big improvement over the Core2Duo. Its a good 700 MHz faster, much faster bus with significantly faster RAM. The first Core i3 processors were launched on January 7, 2010. 4

Malicious buffer overflow attacks pose a significant securitythreat to businesses.These attacks cost businesses precious productivity time, whichcan equal significant financial loss.It allows the processor to classify where application code can executand where it cannot in the memory.When a malicious worm attempts to insert code in the buffer,the processor disables code execution. 19
