The C.P.U. ?• Central Processing Unit.
Which one is it?
![Page 6: How are they called?](https://reader036.vdocuments.mx/reader036/viewer/2022081503/56816083550346895dcfaca4/html5/thumbnails/6.jpg)
System Unit• The system unit is the core of a computer
system. Usually it's a rectangular box which contains many electronic components that process data. The most important of these components is the central processing unit (CPU), or microprocessor, which acts as the "brain" of your computer.

Microprocessor – The C.P.U.
• A microprocessor incorporates the functions of a computer's central processing unit (CPU) on a single integrated circuit (IC, or microchip). Wikipedia http://en.wikipedia.org/wiki/Microprocessor

32 or 64 Bits?• The amount of bits they can use to perform any
given operation. • It refers to the amount of digits it can handle, or
its precision. • It’s not the same to be able to add numbers 32
digits long than add numbers 64 digits long. • Faster in very specific situations. Requires special
software.

o All programs you are running.o The more windows, programs and files you open the more RAM you
need.• Used only by the computer, users can’t access
them.
