Inputting Data into the Computer
I. INTRODUCTORY CONCEPT
In a small sized office, computerizing a paper system can create additional space at
the same time saves the environment, as there is no longer a need to use more paper to
store a large volume of files.
INPUT DEVICE
An input device is used to provide data and control signals to an information processing
system such as a computer or other information appliance.
Examples of input devices
A. mouse
B. keyboard
C. digital cameras
D. microphone
E. scanner
A. Mouse
Mouse is used to interact with items on your computer screen. You can
move objects, open them, change them, throw them away, and perform
other actions all by pointing and clicking with your mouse.

Kinds of Mouse
Optical
Optical mice ditch the ball/roller mechanics for a small glowing light and
a sensor.
1. Touchpads
Found on many laptops, this square pad lets you
move the cursor by dragging your finger across
its surface.
2. Wireless
Wireless mice work just like their keyboard
counterparts; in fact, some share the same
receiving unit, which plugs into your computer’s
USB or mouse PS/2 port.
3. PS/2
PS/2 an older mouse comes with a PS/2-style
connector, which still work fine. Just don’t ever unplug
the mouse while the computer is turned on, the mouse
will stop working — even after you frantically plug it back
in.(Restart the computer, and the mouse will begin
working again.)
B. Keyboard
Keyboard is an input device
that leads to enter information
into your computer. But did you

know you can also use your keyboard to control your
computer? Learning just a few simple keyboard commands
(instructions to your computer) can help you work more
efficiently.
The keys on your keyboard can be divided into several groups based on
function:
Typing (alphanumeric) keys. These keys include the same letter, number,
punctuation, and symbol keys found on a traditional typewriter.
Control keys. These keys are used alone or in combination with other keys to
perform certain actions. The most frequently used control keys are Ctrl, Alt, the
Windows logo key, and Esc.
Function keys. The function keys are used to perform specific tasks. They are
labeled as F1, F2, F3, and so on up to F12. The functionality of these keys differs
from program to program.
Navigation keys. These keys are used for moving around in documents or
webpages and editing text. They include the arrow keys, Home, End, Page Up, Page
Down, Delete, and Insert.
Numeric keypad. The numeric keypad is handy for entering numbers quickly. The
keys are grouped together in a block like a conventional calculator or adding
machine.

Keyboard comes with three ports supported technology USB, PS2, and Wireless.
C. Digital camera
Digital camera is used to capture photographs in digital memory. Most cameras
produced today are digital and while there are still dedicated
digital cameras. Many more cameras are now incorporated
into mobile devices like smartphones which can be used
among many other purposes
D. Microphone
Microphone is a device that captures audio by converting
sound waves into an electrical signal.
E. Scanner
Scanner is a device that captures images from
photographic prints, posters, magazine pages, and similar
sources for computer editing and display
STORAGE DEVICE
What are storage devices?
A storage device is a hardware device capable of holding information. The computer has
many types of data storage devices. Some of them can be classified as the removable
data storage devices and the others as the non-removable data storage devices.

1. Primary Storage
Is also known as main storage or memory, the main area in a computer in which
data is stored for quick access by the computer's processor.
2. Secondary Storage
Referred to as external memory and secondary storage is a storage medium that
holds information until it is deleted or overwritten regardless if the computer has power. It
refers to storage devices and storage media that are not always directly accessible by a
computer. This differs from primary storage technology such as an internal hard drive
which is constantly available.
Examples of secondary devices
Solid State Drive
Hard Disk Drive

3. ODD (Optical Disc Drive)
CDs tend to be used for large files (but
smaller than 1 GB) which are too big for a
floppy disc to hold such as music and
general animation.
DVDs are used to hold very large files
(several GB) such as movie films. Both CDs
and DVDs are portable i.e. they can be
transported from one computer to another.
Both can be used to store computer data.
CD ROM/DVD ROM Applications which
require the prevention of deletion of data.
USB flash drives are typically removable and rewritable
much smaller than a floppy disk. Storage capacities
typically range from 64 MB to 64GB. USB flash drives
offer potential advantages over other portable storage
devices, particularly the floppy disk.
Flash memory cards
A memory card or flash memory card is a solid-
state electronic flash memory data storage
device used with digital cameras, handheld and
Tablet/Mobile computers, music players, video

game consoles, and other electronics.
External/Portable hard disk
External/Portable hard disk are good fun because you
can carry data about all over the place and transfer
information, programs, pictures, etc. between
computers.
II. LEARNING COMPETENCIES
