10. 7
Input: Information and programs are entered into the computer through input devices such
as the keyboard, disks, or through other computers via network connections or modems
connected to the Internet. The input device also retrieves information off disks.
Output: Output Devices display information on the screen (monitor) or on the printer and
sends information to other computers. They also display messages about what errors may
have occurred and brings up message or dialog box asking for more information to be
inputted. The output device also saves information on the disk for future use.
Processing: The CPU or central processing unit is sometimes called the Control Unit and
directs the operation of the input and output devices. The memory or RAM temporarily stores
information (files and programs) while you are using or working on them.
INPUT DEVICES
DEVICE NAME DESCRIPTION
Keyboard
This is a primary input
device used with a
computer. It is composed
of different buttons with
specific function, letters,
numbers, and symbols.
Mouse
This is a device that
controls the movement of
the cursor or pointer on a
display screen.
Touch Screen
This is a computer screen
that can be used by
touching it with a finger or a
stylus pen to interact with a
computer.
11. 8
Microphone
This is a device that accepts
audio input from users.
Webcam
This is a typically small camera
that sit on a desk, attach to a
user's monitor, or are built into
the hardware. Webcam can be
used during a video chat session
involving two or more people,
with conversations that include
live audio and video.
Computer Scanner
This is a device that optically
scans images, printed text,
handwriting or an object and
converts it to a digital image.
Graphics Tablet
It is also known as a digitizer,
drawing tablet, drawing pad,
digital drawing tablet, pen
tablet, or digital art board) is a
computer input device that
enables a user to hand-draw
images, animations and
graphics, with a special pen-
like stylus, similar to the way a
person draws images with a
pencil and paper.
Joystick
This is an input device that
can be used for controlling the
movement of the cursor or a
pointer in a computer device.
12. 9
Aside from input devices that is used in entering data, computer also needs
application software that interact between user and computer hardware. Each application
software has its own specific function, so determining the appropriate software to be used
based on the tasks to be done is necessary.
Some of the common application software used:
Word Processor – this software main purpose is to encode data.
Examples: MS Word, Libre Office Writer, Open Office Writer
Spreadsheet – it is a spreadsheet program, which contains several columns and rows,
where each intersection of a column and a row is a “cell.”
Examples: MS Excel, Libre Office Calc, Google Sheets
Database Software - is a collection of information that is organized so that it can be easily
accessed, managed, and updated.
Examples: MS Access, MySQL, Oracle
Presentation Software - is a category of application software that is specifically designed
to allow users to create a presentation of ideas by stringing together text, images and
audio/video.
Examples: MS PowerPoint, Prezi, Zoho Show
Desktop Publishing Software - software is designed for creating visual communications
such as brochures, business cards, greeting cards, web pages, posters, and more for
professional or personal printing online or on-screen.
Examples: MS Publisher, Adobe InDesign, QuarkXPress
Graphics Programs- is a software application that allows you to draw, edit, and manipulate
an image or graphic file.
Examples: CorelDraw, Photoshop, and Computer Aided Design (CAD)
Educational Software- these include tutorials and electronic lessons that give students’
knowledge or training in a particular subject or skill, such as Math or Science or in gardening
or cooking.
Web Browser Software – this is a software application for accessing information on the
World Wide Web.
Example: Internet Explorer, Google Chrome, Mozilla Firefox, Safari, Opera

Computer Storage Devices Computer need storage devices before and after processing
the data to store information and access later.
STORAGE DEVICES DESCRIPTION EXAMPLE
Volatile Storage Device
This is a computer memory
that requires power to
maintain the stored
information.
RAM
Non-Volatile Storage Device
This is a computer memory
that can retain the stored
information even when not
powered.
ROM, Flash drive,
Memory Stick, SD
Card, Hard Disk
Despite essentially functioning as opposites, both primary storage and secondary
storage often work together to create ideal storage conditions. For instance, when you save
your work in Word, the file data moves from primary storage to a secondary storage device
for long-term retention. Likewise, a primary storage device retrieves data from a secondary
source to speed up access.
PRIMARY STORAGE DEVICE
A primary storage device is a medium that holds memory for short periods of time
while a computer is running. Although it has a much lower access time and faster
performance, it is also about two orders of magnitude more costly than secondary storage.
Example: RAM & Cache
SECONDARY STORAGE DEVICE
Secondary storage hard drives, which store data for the long-term include internal
and external types.
Example: Hard Disk, CD, DVD, Flash Drive, Memory Stick, SD Card
14. 11
Hard Disk
Computer Storage Devices
Fixed Storage Devices – devices that is attached inside the computer unit.
This is a type of computer memory that can
be accessed randomly.
It is usually installed internally in a
computer, attached directly to the disk
controller of the computer's motherboard.
Removable Storage Devices – devices that can be detach after use and use again later
to another computer.
Flash drives are often referred to as pen
drives, thumb drives, or jump drives.
Flash drives connect to computers and
other devices via a built-in USB Type-A or
USB-C plug.
This is a disc drive that uses laser light or
electromagnetic waves within or near the
visible light spectrum as part of the process
of reading or writing data to or from optical
discs.
An external drive is just a hard drive (HDD)
or solid-state drive (SSD) that is connected
to a computer on the outside rather than on
the inside.
Cloud Storage – some websites offer free storage to users. They just need to sign up
before they can avail these free storages.
Cloud storage is a cloud computing model
that stores data on the Internet through a
cloud computing provider who manages
and operates data storage as a service.
Example: pCloud, Google Drive, Dropbox,
Microsoft SkyDrive, iCloud, Amazon drive,
OpenStack
RAM (Random Access Memory)
Flash Drive
Optical Drive
External Hard Drive

Ergonomics” is the science of designing the workstation to fit within the
capabilities and limitations of the worker. The goal is to eliminate discomfort and risk
of injury due to work.
It is important to make sure you have
backups of all documents you created. Nowadays all
files could be accessed anywhere just save it using
online platform.
