Computer Performance

1. Cores

   • What?
     • Individual processors
       • Quad core-4
     • Quad core-2
     • Allows the devices 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

2. RAM

3. Clock Speed

   • What?
     • Cycles per second
       • Fetch-Decode-Execute-Cycle
         • Instructions
     • Measured in Hz
       • 1GHz-1,000,000,000 instructions per second
         • 1Hz=instruction/cycle per second
   • How?
     • Programs will toad faster as more instructions can be processed per second
   • Why?
     • Minimum specification for software not being met
     • Devices may be slow at loading programs/applications and files

4. Cache

   • What?
