• Central processor. The
processor is called the brain
of the computer. The
computer brain is made up
of thousands of transistors. It
is responsible for performing
all functions of computer
programs - without a CPU
you do not have a computer .


• RAM is a chip inside a computer
that temporarily stores
information used by the
computer when it is turned on.
This is one of the main parts of
the computer that ensure fast
system operation. The increase
in RAM for the computer leads
to an increase in the functioning
of the system. RAM only runs
while the computer is powered
on, and when it is powered off,
all data stored in the RAM is
lost. This makes it an energydependent memory.


• The motherboard is the
main board in the
computer. It is attached
to RAM, video card,
processor, fan. It also
contains a chip with a
BIOS and a battery for
its operation.


A video card is a device that

computer's memory or the
adapter itself, into another
form intended for further
display on the monitor
screen. At present, this
function has lost its basic
meaning and, above all, a
graphic adapter is
understood as a device with
a graphics processor - a
graphic accelerator, which is
engaged in the formation of
the graphic image itself.


• Cooler - applied to
computer subjects - slang
computer name of the
device - a combination of
a fan and a radiator
installed on the electronic
components of a computer
with increased heat
generation (usually more
than 5 W): CPU, graphics
processor, chipset chips,
Power Supply


• The computer power
supply unit is a
secondary power source
intended for supplying
computer units with DC

• A modem (short for
can also be attributed to
one of the main
