The document discusses the role of computers in community education, emphasizing their use as teaching aids that promote learning through interactive and personalized instruction. It covers essential hardware components, such as memory, storage devices, input and output devices, and highlights the advantages of computer-assisted learning, including increased motivation and self-esteem among learners. Additionally, it touches on modern technologies like telecommunications and teleconferencing, which enhance educational delivery and pose implications for social equity.

2. Computers

3. Computer
 A computer is a programmable
machine.
The two principal characteristics of a
computer are:
◦ it responds to a specific set of instructions
in a well-defined manner;
◦ it can execute a prerecorded list of
instructions (a program).

4. Modern Computers Defined Modern computers are electronic and digital. The actual machinery -- wires,
transistors, and circuits -- is called hardware; the instructions and data are called
software.
 All general-purpose computers require the following hardware components:
 Memory enables a computer to store, at least temporarily, data and programs.
 Mass Storage Device allows a computer to permanently retain large amounts of
data. Common mass storage devices include disk drives and tape drives.
 Input Device usually a keyboard and mouse, the input device is the conduit
through which data and instructions enter a computer.
 Output Device a display screen,
 Printer or other device that lets you see what the computer has accomplished.
 Central Processing Unit (CPU) The "brain" of all computers and console
systems. The CPU is like a manager or boss. They tell what the other
components of the system should be doing at a given moment.

5. COMPUTERS
 used as teaching aids to help individuals to learn. They serve
to access information for learning, as well as to promote the
formation of new ideas.
 students can be assisted in writing, graphing, idea generating,
word processing, and applying managerial principles to
problem solving and research.
 can now be programmed to be interactive.
 Learners can proceed at their own pace, skip ahead, or review.
 For the uneducated, non-traditional and reentry students, computers
allow individual learning in an environment where they can avoid
embarrassment, track their own progress, and engage in drill and
practice until they are competent.
 student get a variety of responses by way of animation, graphics, and
audio.
 beneficial to instruction are computer learning in mathematics,
computational skills, basic reading skills, and general education.
 lend itself to positive attitudes toward learning such as by way
on increased motivation and improved self esteem among
learners.
 Used as enhancements to traditional instruction.

6. HIGH TECH
PERIPHERALS
Specialized peripherals are electronic devices which can be
attached to computers in order to expand the computer's use.

7. There are
devices that give
options to learners for
registering decisions
on the screen and
participating actively
in the learning
process.

8. Light Pen
Light pens provide a
very precise pointing
capability directly on
the screen.

9. Joystick
Input device
consisting of a stick
that pivots on a base
and reports its angle
or direction to the
device it is
controlling.

10. Game paddle
an input device
commonly used with
games that may
contain various
buttons used to steer
and utilize different
options in a game.

11. A computer
mouse
is an input device that
is most often used with
a personal computer.

12. A local area network
(LAN) is a group of
computers that are
connected together in a
localized area to
communicate with one
another and share
resources such as
printers.

13. The videodisc when
linked with the
computer can allow
access to scenes or
segments useful to a
topic being studied.
The videodisc
produces full-color
pictures and a sound
track. Text, graphics,
photos, slides and
films can also be
combined in a single
medium.
Videodisc

14. Telecommunications
It is the transmission and
reception of messages
over long distance. It
allows the transfer of the
spoken and written word
to anyone, anywhere, at
anytime. With the advent
of fiber-optic technology,
current transmission
capabilities consist in a
billion bits of information
per second.

15. It is designed as a
substitute for face-to-
face meetings and
travel. It can transmit
voices, at times
images, and allows for
instruction at off-
campus locations.
Teleconferencing

16. It is the use of the
classroom
computer to search
through data base
information
sources and to get
topic information.
Telecomputing

17. Implications of the New Technologies
o Methods and content of instruction, both
supplementing and changing the relationship
between the teacher and the learner.
o Have the potential of broadening the gap between
haves and have-nots in society and throughout the
world.
o Have freed many individuals to enjoy their leisure
and to work at home in a distraction-free
environment.
o Most educational services are foreseen to be
delivered electronically by teleconferencing, cable
and satellite television, computer networks and other
