1. Clock speed

   • What?
     • Clock speed processes instructions.
     • Fetch-Decode-Execute cycle.
     • It is measured in hertz (Hz) 1 GHz (1,000,000,000)
       • 1 GHz - 1,000,000,000 instructions per second
   • How?
     • Can process more instructions per second, therefore programs will run/load faster.
     • Software/games would run smoothly
   • Why?
     • Current processer is slow.

2. Cores

   • What
     • Dual core - 2 Quad core - 4
     • It multi-tasks.
   • How?
   • Why?

3. Cache

   • What?
     • The cache is memory that is very fast. Its very expensive to buy and has 6 MB.
   • How?
   • Why?
