identifying purposes and characteristics off processors Flashcards
what is the role of cpu?
control and direct activities using buses
whats the largest cpu manufacturers?
intel and amd
what was used as a cpu prior to 1981?
dual in line package (dip)
what do modern cpus use as ff?
lga
what is hyperthreading a form off?
for of simuktaneous threading (smt)
what can smt do?
have multiple instructions operating on seperate data in parralel
what can htt do?
schedule two processes at the same time
what does symmetric multiprocessing (smp) do?
uses 2 or more processers to use the same resources
what must os support to take advantage of htt?
smp
what does multicore architecture have?
separate processor dies in the same package
what does systems have to be written in for smp to work?
parralel
explain intels core 2 labelling?
doesnt mean theres 2 processors on a single die
explain core 2 microarchitecture?
solo/duo has single die
quad has two dies
what is cpu throttling?
reducing operating frequency when in less demand or battery saving is in process
how can you see cpu throttling in action?
lower clock frquency
how is speed measured?
mhz or ghz
what does the mb have to measure speed?
oscillators
what happens when a current goes through quart crystals?
vibrates
what is the piezoelectric effect?
when quarts crystals vibrate when a current is run through them
what is a 32 bit/64 bit processor?
chunks of info per unit of time
where is virtualisation supported in?
in the hardware even though its a software its built oin
Is there a need to install gpu?
theyre already built in
what is a gpu?
large chip on the graphics adapter
what does gpu help minimise?
off package communication
what is disable execute bit?
it doesnt allow any code to be erased when its in a certain place in memory location this prevents and malicious overun attacks
