cpu configuration
The CPU Configuration attributes refer to configuration characteristics such as CPU ID, CPU Family, and Clock Speed.
clock speed
measured in gigahertz
average is around 1-3.8 ghz
can be upgraded by a intel core
each 1 tick is one fde cycle
some brands that make CPUs are :
intel AMD
QUALCOMM
ARM
rockchip
Motorola
embedded systems
cheap to make
easy to manufacture
little machine inside a multi purpose computer
overclocking
overclocking is something people do to make their CPU run faster than intended they do this by increasing the clock speed so it can perform more tasks at once
people who would do this are gamers or people trying to get their cpu as fast as possible
downsides
casues cpu to get really hot
could lead to crashes
could lead to permanent damage
ram and cpu
Both RAM and the CPU work synchronously to ensure that your computer's performance fits your needs and you have a good experience when using your device
