3. Motherboard
• A motherboard (also called mainboard, main
circuit board, system board, baseboard, planar
board, logic board, and mobo) is the main
printed circuit board (PCB) in general-purpose
computers and other expandable systems. It
holds and allows communication between
many of the crucial electronic components of a
system, such as the central processing unit
(CPU) and memory, and provides connectors for
other peripherals. Unlike a backplane, a
motherboard usually contains significant sub-
systems, such as the central processor, the
chipset's input/output and memory controllers,
interface connectors, and other components
integrated for general use.

4. CPU(central prossessing unit)
• The main part of any computer is the central
processing unit or CPU.
• The CPU does all of the operations and
calculations that make a computer run. It is
made up of a control unit and an arithmetic
and logic unit (ALU). The control unit does
just that, it controls which instruction is
carried out next.
• The arithmetic and logic unit performs
mathematical calculations that allow the
computer to execute many programs.

5. The process generally works like this:
1.the computer receives some input from
an input device such as a keyboard (i.e., a
stroke),
2.that input, or instruction, is processed
through the central processing unit, very
quickly, and
3.some output is displayed on a screen or
sent to a printer, etc.
That’s it. Input is received, it is processed,
and output is generated.

6. • RAM (or random access memory) is called the main
memory because it is available and quicker—it allows the
computer to randomly access data and “appear” to be
doing many things at one time, when in reality a computer
processes one thing at a time (it is just able to process
billions and billions of things in one second through its
CPU).
• RAM needs electricity to operate and therefore it typically
goes away when the computer is shut off. It is called
volatile memory.

7. Secondary memory
is the
computer’s permanent memory
and it allows a person to save files
and information on the hard drive.
It does not go away when a
computer is shut off, therefore
your file is still there when you
turn your computer back on. It is
not volatile.
