1.1 system architecture

1. processor

   • number of cycles per second

2. MHz

3. GHz

   • executes 1 billion instructions per seconds

4. Hertz

5. intructions

6. execute

7. embedded system

   • examples
     • microwave

8. clock speed

   • doubling this will double the number of instructions executed per second

9. cache

10. core

    • quad core
    • dual core

11. ram

    • random access memory a place where data and instructions that are currently in use by the cpu or have recently been used are stored

12. mother board

    • motherboard connects all components to each other which allows them to communicate

13. bios

    • basic input output system. a small program is stored on the rom chip to load the operating system correctly

14. cpu

    • central processing unit. used to control and execute commands within the computer. the performance is measured in GHz which is the number of processes which can be executed in 1 second

15. cmos battery
