Hardware

1. CPU

   • Clock Speed
     • Number of cycles per second
     • MHz
     • GHz
   • Cache memory
     • Smaller memory
     • Faster memory
     • Stores copies of frequently used data
   • Multicore processors
     • Adds speed
       • Processes more than one instruction at a time
     • Many types
       • Octa
       • Hexa
       • Quad
       • Dual
     • Two or more independent processing units
   • Made up of switches
     • On (1)
     • Off (0)

2. Logic gates

   • NOT gate
     • Output is oppposite of input
   • AND gate
     • Both inputs have to be on for output to be on
   • OR gate
     • Atleast one input must be on for output to be on
