Input and output devices allow information to enter and exit a computer. Input devices include keyboards, mice, scanners, and microphones. Output devices display or print information for users, such as monitors, printers, speakers and projectors. Together, input and output devices facilitate interaction between users and computers by allowing data and instructions to be entered and results received in a usable form.

2024.06.01 Introducing a competency framework for languag learning materials ...Sandy Millin
http://sandymillin.wordpress.com/iateflwebinar2024
Published classroom materials form the basis of syllabuses, drive teacher professional development, and have a potentially huge influence on learners, teachers and education systems. All teachers also create their own materials, whether a few sentences on a blackboard, a highly-structured fully-realised online course, or anything in between. Despite this, the knowledge and skills needed to create effective language learning materials are rarely part of teacher training, and are mostly learnt by trial and error.
Knowledge and skills frameworks, generally called competency frameworks, for ELT teachers, trainers and managers have existed for a few years now. However, until I created one for my MA dissertation, there wasn’t one drawing together what we need to know and do to be able to effectively produce language learning materials.
This webinar will introduce you to my framework, highlighting the key competencies I identified from my research. It will also show how anybody involved in language teaching (any language, not just English!), teacher training, managing schools or developing language learning materials can benefit from using the framework.

2. HOW??
•Do you ever wonder how
information gets in your
computer and how comes
out in a form you can use?
So, It is only possible with
the help of Devices.
3. It can be defined as the components or
peripeharls which are attached to the
computer to enter the data and get the desired
result.
Examples:-
Monitor,Keyboard,Mouse,Printer,etc.
What is Device?
7. Pointing Devices
A pointing device, or sometimes called a pointing tool,
is a hardware input device that allows the user to
move the mouse cursor in a computer program or

17. Printer was invented by Johannes Gutenberg
In computing, a printer is a peripheral which makes a persistenthuman-
readable representation of graphics or text on paper or similar physical
media
Types Of Printer:-
1. Impact Printer :- An impact printer makes contact with the paper. It
usually forms the print image by pressing an inked ribbon against the
paper using a hammer or pins. Eg. Dot-Matrix , Daisy Wheel, Etc.
2. Non-Impact Printer :- Non-impact printers do not use a striking device to
produce characters on the paper; and because these printers do not
hammer against the paper they are much quieter. Eg. Inkjet , Laser, Etc.
PRINTER
18. The term “Audio Output Device" refers to any device that
attaches to a computer for the purpose of playing sound, such
as music or speech. The term can also refer to a computer
sound card.

19. Projector was invented by Charles Francis Jenkins.
A projector or image projector is an optical device
that projects an image (or moving images) onto a
surface, commonly a projection screen.

20. CONCLUSION
Input and Output devices are indispensible
components of a personal computer.
Act as a intermediary between the user and the
machine in the process of communication.
Are the beginning and end of all processes,
instructions executed in the machine.
without these devices, no operation can be
effectuated.
