Computer Performance

1. Cores

   • what
     • Used for multitasking
     • Dual core - 2
     • Quad core - 4
     • Individual processors
   • why
     • Minimum specification for software not being met
   • how
     • Improves performance by allowing multiple applications to run at one time
     • Improves multitasking

2. Clock Speed

   • how
     • Applications will run faster
   • what
     • Cycles per second
       • Fetch-Decode-Excecute
         • Instructions
     • Measured in Hz
       • 1Gz - 1,000,000,000 instructions per second
       • 1Hz - 1 instruction/cycle per second
   • why
     • Your computer may be slow at loading programs
     • Minimum specification for software not being met

3. Cache

   • Stores frequently accessed data.
   • Your computer is running slow.
   • You would get a CPU with a larger capacity of cache.
