Functions of the
computer
Categorize parts of a
computer by function
(input, output,
processing, & storage)
and explain how parts
work together
Direct – PowerPoint
presentation with
discussion and
questioning included
Quiz
Compare between
human and computer
parts & functions
Indirect – Comparison
activity to make
predictions and draw
analogy between humans
and PC’s
Parts / Functions
Direct – watch video
Indirect – have students
review web article from
“Howstuffworks” web
site
Class will be divided into
4 groups and given a part
of the PC and asked to
come up with a human
comparison and share
with the whole class.
Monitor students group
discussion and use
worksheet to ensure
correct comparisons are
made.

Four Functions of a Computer

•
Input
Process
Storage
Output
In 4 assigned groups spend five minutes
discussing what you think human function relates
to your assigned function and computer
examples
Motherboard
Contains:
• CPU
• Ports
• Memory chips
that control
functions like
video &
networking
•Connects to
main power
source
Input
• Gets information into the computer and translates to digital
form. Comes from devices such as:
–
–
–
–
–
–
Keyboard (Qwerty style from typewriters)
Mouse
Scanner
Microphone
Camera
Graphic tablet
• Texts, graphics, sounds, video, music, are all transformed
into binary code. Letters, words, numbers, and even colors
all use the universal ASCII language
• ASCII – zeros and ones stand for electrical pulses (1 = +, 0 =
neutral
– Each zero or one is a bit and 8 bits = a byte
– A byte is a single letter, number, symbol, or sound
Human comparison – Ears, Eyes, Nose, Mouth
Input Devices
Process
• CPU is main processing unit of a computer
• It coordinates all of the actions of the machine by following
instructions such as:
– Perform calculations
– Interact with other components to operate the computer
• The microprocessor is the primary work area where
information gets processed
• Software (i.e. games or programs on the computer) are the
sets of instructions that you give to the processor
• Microprocessor primary steps are:
– Fetch
– Decode
– Execute
Human Comparison – Certain Sections of the Brain or Digestive
System
Storage
• Computers have two types of storage
– Temporary
• RAM or Random Access Memory stores information as you
use it
• Constantly gets erased and rewritten as you open & close
files
– Long-term
•
•
•
•
Hard Drives
CD-ROMs
Floppy disks
Flash Drives
– The capacity of these types of memory vary – but the
more you have, generally the better
Human Comparison – Brain (Different parts – long-term
and short –term memory)
Process and Storage
All of these
can store the
same amount
of information
Output
• Display the information the computer has
been processing or retrieve the information or
result of the instructions given earlier
– Monitor
– Printer
– Speakers
Human Comparison – Written work, speech, song,
poem, painting, sculpture, repaired car
