Information Technology
Information Technology is the process of
gathering and storing data to be used in
various forms: It has:
– Streamlined access to vast sources of
information
– Allows us to produce more accurate forms of
communication
– Expanded resource choices
– Enabled us to retrieve data in seconds
Examples of
Information Technology
• Data collected on
paper
• Data stored in
computers
• Data stored in books
• Data stored in
equipment or
machines
Impacts of Information Technology
POSITIVE
IMPACTS
COMPUTERS –
use of a computer
to gather data
easily and store
INTERNET – using
to store information
for easy access
NEGATIVE
IMPACTS
OBSCELENCE –
machines need to
be maintained and
upgraded
INTERNET –
information is not
always accurate or
reliable
Communication Technology
Communication Technology is a process
of giving or exchanging information.
It has:
– Streamlined publishing techniques and allows
us to produce more accurate drawings
– Expanded entertainment choices
– Enabled us to contact people thousands of
miles away
Examples of
Communication Technology
• Cell Phones
• Computer Aided Drafting
• Video Cassette
Recordings
• Internet
• Radio
• Television
• Graphic Arts
Impacts of Communication Technology
POSITIVE
IMPACTS
CAD – using a
computer to
generate drawings
INTERNET – a
means of
communicating
quickly and
inexpensively over
long distances
NEGATIVE
IMPACTS
PAPER USAGE –
people tend to
create and print
more documents
INTERNET –
people tend to
misuse the internet
for personal gain
Bio-related and Agricultural
Technology
• Biotechnology is the application of
the principles of biology to create
commercial products or processes.
• Agricultural Technology is the
application of processes that make it
possible for food to be available
year-round and to conserve
resources.
• Both deal with living things
– Plants
– Animals
– People
Examples of Bio-Related and
Agricultural Technology
Bio-related Technology
• Pharmaceuticals
• Artificial limbs
• Genetic engineering
• Hydroponics
• Imaging devices
• Cardiovascular devices
• Ethics
Agriculture
• Food, Fiber, and Fuel
• Plant growth
• Machines
• Production of ag
products
• Transportation of ag
products
• Storage of ag products
Impacts of Bio-Related and
Agricultural Technology
POSITIVE IMPACTS
NEGATIVE IMPACTS
HEALTH – improves
quality of life
HEALTH – Drugs may
cause birth defects
ENVIRONMENTAL –
can produce more food
per acre than before
ENVIRONMENTAL –
Chemicals have found
their way into ground
water, polluting good
drinking water
Medical Technology
Medical Technology is the study of
medicine through the use of and advances
of technology, such as medical
instruments and apparatus, imaging
systems in medicine, and mammography.
Related terms: Bio-medical Engineering

Pharmaceuticals
Artificial limbs
Imagining equipment
Ergonomics – the study of designing
equipment to fit the human body, its
movement & thinking patterns
Impacts of Medical Technology
POSITIVE IMPACTS
HEALTH – improves
quality of life
NEGATIVE IMPACTS
HEALTH – use of
technology may hinder
life span
DISEASE – research on DISEASE – not all
controlling diseases and cultures embrace use of
their spread is shortened vaccines and thus
disease spreads
Environmental Technology
Environmental Technology is study of the
processes to control waste, soil erosion,
reducing sediment in waterways,
conserving water, and improving water
quality, artificial ecosystems, and the
effects of technology on the development
of flora and fauna.
Examples of Environmental
Technology
• Conservation
• Synthetic energy
• Waste management
Impacts of Environmental
Technology
POSITIVE IMPACTS
NEGATIVE IMPACTS
EARTH – improves
quality of life
EARTH – use of
technology may hinder
life span of the planet
DISEASE – reduces
chance of disease from
bad air and chemicals
DISEASE – economical
forces the need to make
choices that are not
easily made
Production Technology
Production Technology is the
manufacturing of physical goods on an
assembly line and the construction of
structures on a job site.
Manufacturing
• Manufacturing is the process of changing
materials into usable products
• Natural (found in nature) or
• Synthetic (human-made)
– Most takes place in factories on assembly
lines
– Results in items that are either consumer
products (used up) or industrial products
(used to make other products)
Examples of Manufacturing
Technology
• Clothing
• Entertainment
devices
• Automobiles
• Chemical products
• Lumber
• Steel
• Food
Construction Technology
Construction Technology is the
study of the processes to
– Build a structure – made by joining
parts to meet a certain need.
• Involves building a foundation, erecting the
super structure, and finishing work.
– Support the load – external force on an
object.
– Control the quality of construction using
control systems.
Examples of Construction
Technology
• Human-made
structure:
–
–
–
–
–
–
Houses
High-rise buildings
Bridges
Roads
Dams
Schools
Impacts of Production Technology
POSITIVE IMPACTS
MANUFACTURING –
new products help to
make our life easier and
increase leisure time.
NEGATIVE IMPACTS
MANUFACTURING –
many industries use
materials that can harm
the environment.
CONSTRUCTION –
provides shelter,
improves roads, creates
employment
opportunities.
CONSTRUCTION –
noise and debris, traffic
problems, accidents &
injuries

Transportation Technology is
the process by which people,
animals, products, and materials
are moved from one place to the
next.

Use of energy
Energy and Power Technology
• Energy is the ability to do work.
• Power is the rate at which energy is
transformed from one form to another or
as the rate at which work can be done.
• Technological products and systems need
energy to function.
• The availability of energy often determines
the development of technology.
Examples of Energy and Power
Technology
• Chemical Energy
– Gasoline
• Mechanical Energy
– Motion
• Thermal Energy
• Electrical Energy
– Electricity
• Radiant Energy
– Light
– Steam
Power Measurement
Examples:
• Horsepower
• Kilowatt
