 It is the temporary storage device
of the computer. It is used to hold
the data that the computer is
working on. The black rectangles
are called RAM chips.
Motherboard
 It is the main circuit board of
the computer that connects
other parts.
CPU fan and heats
 These two components work together in
keeping the CPU from overheating. The metal
is called the heatsink as it conducts heat from
the CPU while the CPU fan blows the air to
the heatsink.
Central processing unit
 This referred to as the
