The
CPU
helps
the
computer
to
read
and
to
follow
the
that
are
in
the
program
.
(
it
is
called
``execute
program´´
)

This
program
is
loaded
in
the

which
instruccion
it
is

.
When
a
computer
shows
you
a
picture
,
it
is
using
its
memory
.
The

All
these
different
parts
work
together
.
It
is
possible
because
there
is
a
program
,
the
,
that
controls
all
these
hardware
components
.
