1. TECHNOLOGY

2. o Technology is the evolution of an idea.
o It’s the thinking of a man or woman who sees before
them an opportunity to improve a process, or to create a
device or object that facilitates, improves or aids
something or someone else.
o Technology is about a unique inspiration given the remit
of creativity and the notion to express that idea as
something real and tangible.
o However, the motives for this spark of creativity aren’t
always as laudable and arguably lamentable.

4. 
 Up till now it is still a mystery
as to who invented the
wheel and when the wheel
was invented.
 It was made by joining
planks of wood together.
 It was a roller made of wood.
WHEEL

5. 
WHEEL
FIRST STAGE
 Early man placed roller
beneath heavy objects
so that they could move
it easily.
SECOND STAGE
 Then they began to place
runners under a heavy
load which they
discovered would make it
easier for the load to drag.
 This was the invention of
sledge.

6. 
WHEEL
THIRD STAGE
 Then they began to
combine the roller and
the sledge.
 As the sledge moved
forward first roller then
the second roller was
placed one after
another to move the
load forward.
FOURTH STAGE
 Men discovered that the
rollers became grooved with
use.
 They soon discovered that
these deeper grooves allowed
the sledge to advance with
greater distance before the
next roller was needed to
come on!

7. 
WHEEL
FIFTH STAGE
 The roller where
changed into wheels.
 The first wooden carts
where made.
SIXTH STAGE
 A slight improvement
was made to the cart.
 Axel were drilled
through the frame of
the cart.
 Axel and wheel were
separated.

8. 
WHEEL
 Today we see that the wheel has gone a great transformation from a
simple one made of wood to the pneumatic rubber tyres that we see
on vehicles today.
 The wheel is probably the most important mechanical inventions of
all times.
 Nearly every machine built since the beginning of the industrial
revolution has or needs wheels.
 Its hard to imagine any mechanized system that would be possible
without the wheel.
 From tiny match gears to automobiles, jet engines and computer disk
drives the principle is same.

10. TRANSPORT
 It is the
movement of
people, cattle, ani
mals and goods
from one location
to another.

11. TRANSPORT
• It is the most
common way of
transport in
olden days.
• It is the least
expensive way of
transport.

12. TRANSPORT
An engine or
motor is a
machine designed
to convert energy
into useful
mechanical
motion.

13. TRANSPORT
 Ship transport is
watercraft
carrying people ,
passengers or
goods.
 Sea transport
has been the
largest carrier of
goods and people
throughout
recorded history.

14. TRANSPORT
• Airline transport
is aircraft carrying
people ,
passengers or
goods.
• It is expensive
than sea line
transport.
• Airline transport
is the fastest mode
of transport.

15. CIRCUITS
o An electrical circuit is a closed loop formed by a power source, wires, a fuse, a
load, and a switch.
o When the switch is turned on, the electrical circuit is complete and current
flows from the negative terminal of the power source, through the wire to the
load, to the positive terminal.
o Any device that consumes the energy flowing through a circuit and converts
that energy into work is called a load.
o A light bulb is one example of a load; it consumes the electricity from a circuit
and converts it into work — heat and light.

16. THERE ARE THREE TYPES OF CIRCUITS.

17. The history of computer development is often
referred to in reference to the different generations of
computing devices.
 Each generation of computer is characterized by a
major technological development that fundamentally
changed the way computers operate, resulting in
increasingly smaller, cheaper, more powerful and
more efficient and reliable devices.

18. *First Generation (1940-1956)=
Vacuum Tubes
*The first computers used vacuum
tubes for circuitry and magnetic
drums for memory, and were
often enormous, taking up entire
rooms.
*They were very expensive to
operate and in addition to using
a great deal of
electricity, generated a lot of
heat, which was often the cause
of malfunctions.

19.  Transistors replaced vacuum
tubes and ushered in the second
generation of computers.
 The transistor was invented in
1947 but did not see widespread
use in computers until the late
1950s.
 The transistor was far superior
to the vacuum tube, allowing
computers to become smaller,
faster, cheaper, more energy-
efficient and more reliable than
their first-generation
predecessors.

20.  The development of the
integrated circuit was
the hallmark of the third
generation of
computers.
 Transistors were
miniaturized and placed
on silicon chips, called
semiconductors, which
drastically increased the
speed and efficiency of
computers.

21. • The microprocessor brought
the fourth generation of
computers, as thousands of
integrated circuits were built
onto a single silicon chip.
• Microprocessors also
moved out of the realm of
desktop computers and into
many areas of life as more
and more everyday
products began to use
microprocessors.

22. o Fifth generation computing devices, based on artificial
intelligence, are still in development, though there are
some applications, such as voice recognition, that are
being used today.
o The use of parallel processing and superconductors is
helping to make artificial intelligence a reality.
o Quantum computation and molecular and nanotechnology
will radically change the face of computers in years to
come.
o The goal of fifth-generation computing is to develop
devices that respond to natural language input and are
capable of learning and self-organization.

23.  Cell phone technology is based on RADIO
technology and this was developed in
1940.
 The first official cell was used by Sweden
police in 1946
 First Generation (1G)
 Second Generation (2G)
 Third Generation (3G)
 Forth Generation (4G)

24.  First generation mobile had ability to transfer
call from one place to another while traveling .
 The first cellular network of first generation
was launched in japan in the year 1979 .
 Second generation was launched in the early 90,s
 This generation phones had digital network .
 The second generation network provide internet
and sums facilities .
SECOND GENERATION (2G)

25.  In third generation network it has high IP data
network and mobile broadband .
 Third generation network has high speed
internet , video calling and many more .
 Before the launch of 3G network it was told of
fourth generation .
 This network is faster than 3G network .
 The first to provide this service is Wi MAX in
U.S .
FOURTH GENERATION (4G)

27. • Medical equipment is designed to aid in the diagnosis,
monitoring or treatment of medical conditions.
• Biomedical Equipment Technician or BMET knows how to
operate on the equipments.
• Classification:
Diagnostic equipment, such as ultrasound, MRI.
Therapeutic Equipment such as medical laser, infusion
pumps.
Medical monitors allow medical staff to measure a
patient's medical state.
Medical laboratory equipment like DNA analysis.

industrial robots into intelligent
service providers through robot
technology convergence in
varied areas such as
education, medical
care, silver, national
defence, construction and
maritime fields.

44. DRAWBACKS OF TECHNOLOGY
0 Though we welcome
these blessing of
technology we have
to consider the outer
of the picture also .
0 Man has not been
able to face the
problem created by
inventions of
technology and to
stop the misuse or
harmful
consequences of
scientific inventions.

45. TECH-WARS
0 Again technology has put in
our hands such fiendish
weapons as the nuclear
bombs the guided missiles
and means of chemical and
biological warfare .
0 We are in danger of
destroying ourselves with
these monstrous means
which ironically , are out
own creations.

46. DRAWBACKS OF TECHNOLOGY
0 Machine have made available to
man plenty of leisure instead of
using leisure for creation and
recreation man is misusing it to
get cheap and vulgar
entertainment which destroys his
physical and mental health.
0 Rightly used technology can
bring heaven on earth wrongly
used it can turn this earth into
hell by destroying civilization.
