The document discusses input devices, output devices, processing, and disadvantages of using computers. It provides examples of input devices like keyboards, scanners, and mice. Output devices mentioned include monitors and printers. Processing allows multitasking by switching between tasks on CPUs. Disadvantages of computer use include carpal tunnel, eye strain, too much sitting, and limited learning.

2. Benefits of Computer
The educational benefits of computer technology are
manifold. Computers in classroom provide young children
the opportunity to learn skills, such as touch-typing, and
core types of programs, such as word processing and
spreadsheet applications, they will need throughout their
careers.

3. INPUT DEVICES
In computing, an input device is a piece of computer
hardware equipment used to provide data and control signals to
an information processing system such as
a computer or information appliance.
Examples of input devices:-
Keyboards
Scanners
Mouse Joystick
Digital cameras

4. OUTPUT DEVICES
An output device is any device used to send data from
a computer to another device or user.
Mostcomputer data output that is meant for humans is in
the form of audio or video.

5. PROCESSING
Multitasking is a method to allow multiple processes to
share processors (CPUs) and other system resources. Each CPU
(core) executes a single task at a time. However, multitasking
allows each processor to switchbetween tasks that are being
executed without having to wait for each task to finish.

6. DISADVANTAGES OF USING A COMPUTER
Although there are a lot of advantages to using a computer, there
are also many disadvantages to using a computer (like most
things in life). What type of problems you may personally
encounter while using a computer.
 Carpal tunnel and eye strain
 Too much sitting
 Short attention span and too much multitasking
 Can limit learning and create a dependenc
