1. KEYWORDS

   • PROCESSOR-the logic circuitry that responds to and processes the basic instructions that drive a computer
   • MHz
   • GHz-1 billion cycles per second. maximum frequency of the clock to each core.
   • HERTZ-unit of frequency of one cycle per second.
     • (a change in state or cycle in a sound wave alternating current,or other cyclical waveform)
   • INSTRUCTION- an order given to a computer processor by a computer program
   • EXCECUTE- to run the program in the computer and implication to start it to run
   • EMBEDDED SYSTEM- a combination of computer hardware and software that has a fixed in capability or programmable
   • CLOCK SPEED- the number of pulses per second generated by an oscillator that sets the tempo for the processor
   • CACHE-to store data locally in order to speed up stubsequent retrivels
   • CORE- an organisation defining strength,providing foundation from which the b
