PROCESSORS Flashcards
a PROCESSOR is
a chip responsible for calculations
it makes all the logical decisions
which are the tasks the computer carries out
is known as the brain of the computer
INPUT DEVICES - list
keyboard
mouse
trackpad
a MOTHERBOARD is
The mode of communication between the computer components
it’s responsible for linking together all the components of the computer
a PROCESSOR does
- receive input data
- process this data
- provide output data
FOUR features of PROCESSOR
socket
cores
clock
cache
a PROCESSOR SOCKET does
a type of physical connection between the Processor and the motherboard
responsible for sending energy to the Processor
a PROCESSOR CORE does
are responsible for processing speed
the more cores a computer has the more functions it can execute simultaneously without overloading the system
a PROCESSOR CLOCK does
responsible for defining the frequency the Processor uses to execute a task
the frequency is the rate of cycles per second
measured by Hz[Hertz]
the higher GHz is the lower execution time is
a PROCESSOR CACHE does
is the auxiliary memory of the Processor
is where the most processed data is identified and stored
is an extremely fast computer chip
RAM is
random access memory
comes in different sized sticks
measured in megahertz
BIOS is
basic input operation system
is software before you get into the main computer
it’s like the Setting menu on a phone and is very close to the hardware
a CORE is
an independent processing unit
can execute more than one instruction at a time
a CPU is
central processing unit
executes a sequence of stored instructions i.e. a program
4 CPU steps
fetch
decode
execute
write back
SYSTEM SOFTWARE is
OS all the applications run on it
