Open Ended
Explain one difference between RAM and the Hard-drive.
10
ROM is Read Only Memory
ROM permanently stores the instructions to 'boot up' (start) the computer
(RAM is Random Access Memory - used for running programs)
from RAM to ROM

22
FDE cycle
In the central processing unit (CPU), the next code instruction is fetched from memory (RAM)
fetch
23
FDE cycle
In the central processing unit (CPU), the next code instruction is fetched from memory (RAM)
fetch
decode
The control unit (CU) decodes the instruction, so that it knows what task to process
24
FDE cycle
In the central processing unit (CPU), the next code instruction is fetched from memory (RAM)
fetch
decode
The control unit (CU) decodes the instruction, so that it knows what task to process
execute
The control unit (CU) signals to other parts of the CPU how to execute the task
25
FDE cycle
In the central processing unit (CPU), the next code instruction is fetched from memory (RAM)
fetch
decode
The control unit (CU) decodes the instruction, so that it knows what task to process
execute
The control unit (CU) signals to other parts of the CPU how to execute the task
26
Poll
Each step in the FDE cycle is necessary, of course. BUT if one of the steps were the most important -- which would you VOTE for?
FETCH
DECODE
EXECUTE

FDE cycle simulator
#1 run the turtle code on Trinket
#2 debug line 72 so that the
FDE cycles iterate
#3 can you increase the turtles' processor speed (clockspeed)?
29

31
clock speed video...
32
clock speed is measured in hertz
hertz (1 - 999)
kilohertz (thousand)
megahertz (million)
gigahertz (billion)
33
clock speed is measured in hertz
hertz (1 - 999)
kilohertz (thousand)
megahertz (million)
gigahertz (billion)
press ctrl + alt + del
to open task manager and performance tab
what clock speed is your CPU?
how many FDE cycles per second?
