DRAW THE THING FROM MEMORY
oof
Fetch-Decode-Execute
retrieving an instruction from memory, decoding it and carrying it out
Central Processing Unit (CPU)
brains of the computer
Clock Speed
regulates the internal components of the computer by issuing a high-frequency signal
clock speed determines how quickly the central processing unit (CPU) can retrieve and interpret instructions
Cores
small CPU/processor built into a big CPU
Cache
hardware or software component that stores data so future requests for data can be faster
Pipelining
set of data processing elements connected in series, where the output of one element is the input of the next one
