Computer Performance

1. Clock Speed

   • Why?
     • Current processor is too slow
       • Device is running slowly
     • Does not meet minimum or recommended spec for software required
   • What?
     • The speed at which a microprocessor executes instructions.
     • Fetch-Decode-Executes Cycle
     • Measured in hertz (Hz) - one instruction per second
       • GHz 1,000,000,000 instructions per second
   • How?
     • Software/games wouldrun smoothly
     • Can process more instructions per second, therefore programs will lod/run faster

2. Cores

   • What?
     • Quad core-4
     • Dual core-2
     • Individual processor
     • Allows the device to run applications simultanesously
   • How?
     • Improves multitasking
     • Improves performance by allowing multiple applications to run at the same time.
   • Why?
     • Good for multitasking
     • Minimum specification for software not being met

3. Cache

   • How?
   • Why?
   • What?
