1. Processor

   • ~Brains of the computer system
   • Processes data
   • Executes instructions
   • Processors have a clock speed measured in Hertz
     • Doubling the clock speed will double the number of instructions executed per seconds

2. Processor Speed

   • Measured in Hertz(Hz)
   • Typical speeds have spanned across MHz and GHz
   • 1GHz processor executes 1 billion instructions per second
   • 2 GHz executes 2 billion instructions per second
