Information and Communication
Technology
What is Information and Communication Technology or ICT?
It deals with the use of different communication technologies such as mobile
phones, Internet and etc. to locate, save, send, and edit information.
Having a unified way to communicate is one of the goals of ICT. We spend less because
of ICT.
World Wide Web
• The World Wide Web, commonly referred to as WWW, W3, or simply the
Web is an interconnected system of public webpages accessible through the
Internet. It was invented Sir Tim Berners-Lee in 1989.
• Web pages are what make up the world wide web and it can either be static
or dynamic.
Web 1.0
Web pages are static and not interactive. You can’t post comments or create
an account.
Examples of Websites in Web 1.0

Web 2.0
• term used to describe the present generation of the World Wide Web that
concentrates on its capability of providing people the means to collaborate and
share information online.
• The second stage in World Wide Web
• Dynamic Website o The content of the website changes
• Interactive o The user may be able to comment or create user account
• enables an increased user participation in the web

• Darcy DiNucci, an information architecture consultant, coined the term
Web
2.0 in her 1999 article,
“Fragmented Future”.
• The term was popularized by
Tim O'Reilly and Dale Dougherty at the
O'Reilly Media Web 2.0 Conference in
late 2004 (TechTarget, 2015).
Features of Web 2.0
• Folksonomy - It allows users to categorize and classify/arrange
information using freely chosen keywords (e.g., tagging). Popular social
networking sites such as Twitter, Instagram, Facebook, etc. use tags that start
with the pound sign (#). This is also referred to as hashtag.
• Rich User Experience - Content is dynamic and is responsive to user’s
input. An example would be a website that shows local content. In the case of
social networking sites, when logged on, your account is used to modify what you
see in their website.
• User Participation - The owner of the website is not the only one who is
able to put content. Others are able to place a content of their own by means of
comment, reviews, and evaluation. Some websites allow readers to comment on
an article, participate in a poll, or review a specific product (e.g., Amazon.com,
online stores).
• Software as a Service - Users will subscribe to a software only when
needed rather than purchasing them. This is a cheaper option if you do not
always need to use a software. For instance, Google Docs is a free web-based
application that allows the user to create and edit word processing and
spreadsheet documents online. When you need a software, like a Word Processor,
you can purchase it for a one-time huge amount and install it in your computer
and it is yours forever. Software as a service allows you to “rent” a software for a
minimal fee.
• Mass Participation - It is a diverse information sharing through universal
web access. Since most users can use the Internet, Web 2.0’s content is based
on people from various cultures.
Web 3.0
• also called as Semantic Web

• Semantics – ability of Web technologies to understand and interpret
humangenerated content
• The aim of Web 3.0 is to have machines understand the user’s preferences
to be able to deliver web content specifically targeting the user.
• The Internet is able to predict the best possible answers to your question
by “learning from your previous choices
Trends in ICT
As the world of ICT continues to grow, the industry has focused on several innovations.
These innovations cater to the needs of the people that benefit most out of ICT. Whether
it is for business or personal use, these trends are current front runners in the
innovation of ICT.
1. Convergence
• Technological convergence is the combination of two or more
different entities of technologies to create a new single device.
• Example: Using of smartphone to create word documents that was
previously can only be created using desktop computer.
2. Social Media
• It is a website, application, or online channel that enables web users
to create, co-create, modify, and exchange user-generated content.
• Types of Social media:
1. Social Networks - sites that allow you to connect with other
people with same interests or background.
Examples: Facebook, Google+
2. Bookmarking Sites - sites that allow users you to store and
manage links to various websites and resources, and to tag
Examples: StumbleUpon, Pinterest
3. Social News - sites that allow users to post their own news
items or links to other news sources.
Examples: reddit, dig
4. Media Sharing - sites that allow you to upload and share
media content like images, music, and video.
Examples: Flickr, YouTube, and Instagram
5. Microblogging - sites that focus on short updates from the
user. Those who are subscribed will receive updates.

Examples: Twitter Plurk
6. Blogs and Forums - sites that allow users to post their
content.
Examples: Blogger, WordPress, Tumblr
3. Mobile Technologies
• The popularity of smartphones and tablets has taken a major rise
over the years. This is largely because of the devices’ capability to do
tasks that were originally found in personal computers.
• Different types of mobile operating systems:
1. iOS – used in Apple devices such as the iPhone and iPad
2. Android – an open source operating system developed by
Google. Being open source means several mobile phone
companies use this OS for free.
3. Blackberry OS – used in blackberry devices
4. Windows Phone OS – a closed source and proprietary
operating system developed by Microsoft
5. Symbian – the original smartphone OS used by Nokia
devices
6. WebOS – originally used for smartphones; now used for
smartTVs
7. Windows Mobile – developed by Microsoft for smartphones
and pocket PCs.
4. Assistive Media
It is a nonprofit service designed to help people who have visual and
reading impairments. A database of audio recordings is used to read to
the user. You may visit http://assistivemedia.org/ for several of their
audio recordings.

Online Safety, Security, Ethics and
Etiquette
Online Safety and Security
The Internet, truly, is a powerful tool. It can be used to promote your business, gain new friends, and
stay in touch with the old ones. It is also a source of entertainment through games, online communities,
and everything in between. But like most things in this world, there is always “other side of the coin”.
The internet is one of the most dangerous places especially if you do not know what you are doing with
it. But there is no need to worry; it is never that late. Hopefully, by the end of this lesson, you can
consider how you go about your use of the Internet.
Let us go back to the previous activity. Let us visit each item and see how risky it is to share them.

The Internet is defined as the information superhighway. This means that anyone has access to this
highway, can place information, and can grab that information. This is why social networking sites like
Facebook continue to improve their security features. The threat of cybercrime is very real. Whatever
information we share today could affect our future.
Tips to Stay Safe Online
The Internet is a public place and it is up to you to protect yourself. Here are some tips to help you stay
safe when using the internet.
1. Be mindful of what you share online and what site you share it to.
2. Do not just accept terms and conditions; read it.
3. Know the security features of the social networking site you use. By keeping your profile private,
search engines will not be able to scan your profile.
4. Do not share your password with anyone.
5. Avoid logging in to public networks/Wi-Fi. Browsing in “incognito (or private) mode will NOT
protect you from hackers.
6. Do not talk to strangers whether online or face-to-face/
7. Never post anything about a future vacation. It is similar to posting, “Rob my house at this date.”
8. Add friends you know in real life.
9. Avoid visiting untrusted websites.
10. Install and update an antivirus software on your computer. Use only one antivirus software to
avoid conflicts.
11. If you have Wi-Fi at home, make it private network by adding a password.
12. Avoid downloading anything from untrusted websites.
13. But the software, do not use pirated ones.
14. Do not reply or click links from suspicious emails.
15. Make Online Purchases from Secure Sites
Most people would dispute that there is no such thing as private over the Internet and they may be
right. Some hackers can find a backdoor even if your profile is already set to private. You have no control
whoever is looking at your friend's screen whenever they open your profile or chat with you.

Internet Threats
Here are some of the threats you should be aware of when using the Internet:
1. Malware – or malicious software, is any program or file that is harmful to a computer user.
Types:
a. Virus - a malicious program designed to replicate itself and transfer from one computer
to another (internet, local networks, FDs, CDs, etc.)
b. Worm - a malicious program that transfers from one computer to another by any type
of means.
Ex. ILOVEYOU Worm - The malware originated in the Pandacan neighborhood of
Manila in the Philippines on May 5, 2000.
c. Trojan - a malicious program that disguises as a useful program but once downloaded
or installed, leaves your PC unprotected and allows hackers to get your information.
d. Spyware - a program that runs in the background without you knowing it (thus called
“spy”). It has the ability to monitor what you are currently doing and typing through
keylogging.
Ex. Keylogger – used to record keystrokes done by the user. This is done to steal their
password or any other sensitive information. The key logger software typically uses log
file to store its recording.
e. Adware - a program designed to send you advertisements, mostly as pop-ups.
f. Ransomware - or ransom software is a type of malicious software from cryptovirology
that threatens to publish the victim's data or perpetually block access to it unless a
ransom is paid.
2. Spam - an unwanted email mostly from bots or advertisers. It can be used to send malware.
3. Phishing - its goal is to acquire sensitive personal information like passwords and credit card
details. This is done by sending you an e-mail that will direct the user to visit a fake website and
be asked to update his/her username, password, credit card or personal information.

Protecting Reputations Online
Here are the things you might want to consider before posting something over the internet:
1. Before your post something on the web, ask these questions to yourself: Would you want your
parents or grandparents to see it? Would you want your future boss to see it?
2. If you feel that a post can affect you or other’s reputation, ask the one who posted it to pull it
down or report it as inappropriate.
Copyright Infringement
It is the use of works protected by copyright law without permission for a usage where such permission4
is required.
Here are some tips that could help you avoid copyright infringement:
1. Always assume that the work is copyrighted.
2. Do not copy, share or alter without seeking permission.
3. Review and retain licensing agreements.
4. Consider buying content.
5. Give credit to the original author of the page or information.

Contextualized Online
Search and Research Skills
Tips on Improving Search and Research Skills
Online search and research are more than just ‘googling’ – typing a word in Google and then
clicking the search button. It is a skill that every Internet user should know to do smart searching
and this starts with improving search and research skills to get better results.
Here are the things that you need to know to improve your online search and research skills. This
will guide you to obtain the most relevant information that you need.
1. When searching online, narrow your topic. Identify the key concepts or
important ideas. Assuming that you would like to search for the answer to this question:
“What precautionary measures should you observe when you are
loggedin in a public computer?”
Do not type the whole question in the search box. Typing the whole question often leads
to a large number of and inappropriate search results.
From the question, the keywords are: precautionary measures, observed,
logged-in, public computer.
Keywords are terms that are used in by most search engines to find related documents.
2. Put the word “AND” between each keyword to create a search string.
You may type the following in the search box:
Precautionary measures AND observe AND logged-in AND public
computer
You will notice a decrease in search results as shown below.

3. Identify synonyms of the key words. Not all databases or articles use the same
words to describe a topic. Group similar words together by using the word “OR” for a quick
and relevant search.
In the case of our example: the synonyms of some of the keywords are:
Precautionary measures – preventive measures
Observe – pay attention to
Logged-in – signed-in
You may type the following in the search box:
Precautionary measures OR preventive measures AND observe OR pay
attention to AND logged-in OR signed-in AND public computer
This gives you another set of search results:

4. Review the first pages returned. If these are not helpful, change your keywords
for a better description.
In this case you may remove the phrase “pay attention to” and then type the following in
the search box:
Precautionary measures OR preventive measures AND observe
AND logged-in or signed-in AND public computer. This gives you
another set of search results.
If you think you have found what you are searching for, then you may stop here. Otherwise, you
may proceed with these other techniques.
5. Use the plus (+) sign for a more specific search. Just type + before a keyword
to indicate that the word after the sign is a required word that must be found in the search.
Example: +preventive measures
6. Use the minus (-) sign for a more specific search. If you want to exclude a
word from your search, place a minus sign just before (without any space) the word you
want to exclude.
Example: public computers -personal
7. Use wildcards for a broader search. Wildcard characters (*) let you find
variations of a word.
Example: measur*
8. Use quotation marks to find phrases or names. Enclose the phrase or names
that you want to search in quotation marks.
Example: “precautionary measures"
9. Use several search engines. Search engines are programs that look for documents
based from specified keywords and return these documents where the keywords were
found. Major search engines include Google, Yahoo (which uses Google), AltaVista, Bing,
and Lycos.
Evaluating Websites
To help you evaluate the website’s credibility, here are the questions that you need to answer:
1. What is the domain type of the website?

If it is a personal website, then you should further evaluate the website.
2. Who wrote the article?
Check if the author’s credentials or affiliations are listed so you can tell whether or not
the author is qualified to write the topic. Check also the publisher of the article if it is a
reliable publisher. Make sure that the author provides e-mail or a contact address/phone
number.
3. What is the purpose of the document and why was it produced? It is
also important to check the document’s purpose and why it was produced. The document
should provide accurate information and must be objective in presenting it. Some
websites produce documents for the purpose of motivating users to buy products. If this
is the case, information might be biased. However, bias is not necessarily bad but you
need to investigate the author or connections.
4. When was the document published and updated?
The document should be regularly updated. As to the freshness of the date, it depends
on the information needed. For some topics you want current information. For others,
you want information near the time it became known. The links should also be up-to-
date. There should be no dead links.

Advanced Techniques using
Microsoft Word
Word processor is an application that allows users to create, edit, and print documents.
One of the most widely used word processors is Microsoft Word. It is developed by
Microsoft and was released on October 25, 1983. With Microsoft Word, you can create
random things like calendar, newsletter, invitations, etc. Microsoft Word offers several
elements that can be used in editing documents which is shown in the figure below.
Microsoft Word is a complex program which people use to perform various functions such
as composing and editing, formatting and saving, and printing. With these functions you
were able to correct spelling, grammar, format your text using boldface and italics, and
save your documents electronically to the computer's hard drive.
Mail Merge
This feature of Microsoft Word allows you to create documents and combine them with
another document or data file. It is commonly used when sending out advertising materials
to various recipients.
The simplest solution for the previous scenario is to create a document and just copy and
paste it several times then just replace the details depending on whom you send it to. But
what if you have hundreds or thousands of recipients? Would not that take too many

hours? What if you have a small database on information where you can automatically
generate those letters?
Mail merging basically requires two components:
1. Main Document
The document that contains the body of the message we want to convey or
send.
Example: Letter
2. Data Source
It is your Excel® spreadsheet containing the names and addresses you want
to merge into a Word® document from the Data Source.
How to Perform Mail Merge?
In Mail Merge you need to:
• Create the main document • Create data
source
• Merge data with document
To create a form letter, do the following:
1. Open an existing Word document, or create a new one.
2. Click the Mailings tab.

3. Click the Start Mail Merge command.
4. Select Step by Step Mail Merge Wizard.
Mail Merge task pane appears at the right side of your screen.
5. Choose the type of document you want to create. If you want to create a
letter, select Letters. Six main steps in guiding you to complete a
merge will be displayed at the bottom.
Mail merge
task pane

6. Click Next: Starting document to move to Step
2.
7. Select Use the current
document. Click Next:
Select recipients to move to Step 3.
You will need an address list so Word can automatically place each address into the
document. The list can be in an existing file, such as an Excel workbook, or you can
type a new address list from within the Mail Merge Wizard.

8. From the Mail Merge task pane, select Type a new list,
then click Create.
9. The dialog box of New address list
appears, displaying fields that Word assumes
you need. Select an entry that you don't
need and click the Delete button. Use the
TAB key to move from cell to cell.
When you delete, a confirmation dialog box will
appear.

To customize the address list, click Customize Columns button at the bottom of the
window.
Fill in the recipient list by typing the record’s data. Type the information that’s appropriate
to each field, then press Tab to enter the next field. After filling in the last field, and add
another record just press the Tab key after inputting the last field. When you press the Tab
key on the last field in a record, a new record is automatically created and added on the
next line.
The dialog box of Customized
Address List will appear. The resulting
window lists the Field Names provided.
When you are done, click OK then
customized fields appear as column
headings in the New Address Listdialog
box.

10. Click OK after filling the recipient list. A special Save As dialog box
pops up, allowing you to save the recipient list. Type a name for the address
list then click the Save button.
Return to your document. You are now ready to write your letter, each copy of the
letter will mostly be the same, except the recipient data (name and address). You
have to add placeholders for the recipient data so Mail Merge identifies correctly where
to add the data. If you're using Mail Merge with an existing letter, make sure the file is
open.
11. Click Next: Write your letter. Click the Address Block button to
insert an address block into your letter.

12. Dialog box of Insert Address Block appears. Choose the desired
format for the address block and click OK. The placeholder of Address
block will appear in the document.
Use the Match Fields button to match your field names with the
required fields to correct problems. This may be essential if you created
the address list in another program, such as Excel.

13. Click Greeting Line from the Mail Merge task
pane to insert a greeting line into your document.
Dialog box of Insert Greeting Line will
appear.
14. Choose a
format for the
greeting line and
click OK.

The placeholder of Greeting lines will appear in
the document.
15. To view your merged data, click the Preview Results button on the Mail
merge task pane or on the ribbon to replace the merge fields with data from
your recipient list.

Kinds of Materials
There are various kinds of materials Microsoft Word is capable of integrating to make your
documents richer, more impressive, and more informative.
1. Pictures – these are electronic, “soft copy”, or digital pictures you have saved in
any local storage device. Three common types of picture files:
a. .JPG – pronounced as “jay-peg”. Short term for Joint Photographic
Experts Group. This type of image file can support 16.7 million colors.
Suitable for use when working with full color photographic images.
b. .GIF – This stands for Graphics Interchange Format. This type of
image file is capable of displaying transparencies and animation. It only
supports Only supports 256 colors.
c. .PNG – It stands for Portable Network Graphics. It is capable of
displaying transparencies but not animation. It supports only 16 million
colors.
2. Clipart - This is generally a .GIF type; line art drawings or images used as generic
representation for ideas and objects that you might want to integrate in your
document.
3. Shapes - These are printable objects or materials that you can integrate in your
document to enhance its appearance or to allow you to have some tools to use for
composing and representing ideas or messages.
4. SmartArt - Generally, these are predefined sets of different shapes grouped
together to form ideas that are organizational or structural in nature.
5. Chart - Another type of material that you can integrate in your Word document
that allows you to represent data characteristics and trends.

6. Screenshots - Screenshot. Sometimes, creating reports or manuals for training
or procedure will require the integration of a more realistic image of what you are
discussing on your report or manual.

Microsoft Excel
What is a spreadsheet?
It is a software application that enables a user to save, sort and manage data in an arranged form
of rows and columns.
Beyond arithmetic operations, spreadsheets provide invaluable tools such as functions that are
very useful in calculating data. As a result, spreadsheets have become one of the widely used
software programs, and MS Excel is the most commonly used spreadsheet tool. Spreadsheets can
be used to determine statistical analysis, compute student’s grades, keep track business accounts
and inventories, and manage databases. Spreadsheets are made up of the following:
• Columns – identified with alphabetic headings Rows - identified with numeric
headings

• Cells – are the intersection of rows and columns
• Cell Reference – also known as cell address that identifies a cell on a worksheet.
- B2 and D4 are examples of cell references
- Use cell reference when creating formulas in Excel to ensure that your formulas are
accurate. Take a look at the table below, instead of using the actual values which are 5,
10, and 20 use the cell references A1, A2, and A3.
• Active Cell – the currently selected cell in a spreadsheet and is indicated by a bold
outline that surrounds the cell
The formula in cell A4
refers to the value in cell A1
which is 5 multiplied by the
value in cell A2 which is 10
plus the value of A3 which
is 20.
The formula calculates
and displays the answer
equation
to the A1
multiplied by A2 plus A3
is 70.
The formula
automatically
recalculates when the
value of a referenced cell
is changed.

- B5 is the active cell
• Texts or labels – It identifies the purpose of a cell, it can be a brief instruction, a
title or caption.
• Number data or constant – a value that doesn’t change and is directly inserted
into a cell.
• Formula (mathematical equations) – an expression that calculates the value
of a cell.
• Mathematical Operators – MS Excel uses standard operators for formulas.
• Functions- These are pre-defined formulas that are already available in MS Excel.
Examples of Formula
This formula used
the SUM function to
add the numbers

Note: A formula always begin with an equal (=) sign.
Commonly Used Excel Functions
SUM – Adds all the numbers in a range of cells.
COUNT - Counts the number of cells that contain numbers.

MIN - Returns the smallest number in a set of values.
MAX - Returns the largest value in a set of values.

AVERAGE - Returns the average (arithmetic mean) of the arguments.
SUMIF – Adds the cells specified by a given condition or criteria. SUMIF function has
the following syntax:
SUMIF(range, criteria, sum_range)
• Range - The range of cells that you want to evaluate based on a given
criteria.
• Criteria – It determines which cells will be added.
• Sum_Range – These are the cells containing numeric values and the
cells to add if the condition is met.
For example, you want to find the total ratings of the teachers in terms of the product’s
quality. The formula to use to get the total ratings of the teachers is shown below.

Sometimes the use of sum_range is optional just like in the example below. The formula
in the following example will add the total scores of the students which are higher than
10. Students with scores lower than ten will not be added.
AVERAGEIF - Returns the average (arithmetic mean) of all the cells in a range that meet a
given criteria. AVERAGEIF function has the following syntax:
AVERAGEIF(range, criteria, average_range)
• Range - The range of cells that you want to apply the criteria.
• Criteria – It determines which cells to average.
• Average_Range – These are the cells containing numeric values
and the actual set of cells to average.

For example, you want to get the average of the students’ ratings in terms of the
product’s quality. The formula to use to get the average rating of the students is shown
below.
COUNTIF - Counts the number of cells within a range that meet a single criterion that
you specify. COUNTIF function has the following syntax:
COUNTIF(range, criteria)
• Range – The range of cells to count.
• Criteria – The criteria that determines which cells to be counted.
The formula =COUNTIF(I3:I7,”YES”) will count the number of respondents that voted for
“Yes”.
If you want to count the number of students who got grades of 90 and above in the first
quarter you can use the formula below.

The example below shows the formula on how to count the number of students who got
grades of 85 and above from the first to the second quarter.
IF – This function is one of the most popular functions in Excel. It can perform a logical
test and returns one value if TRUE, and another value if FALSE. The following is the syntax
of IF function:
IF(logical_test, value_if_true, value_if_false)

• Logical Test - A value or logical expression that can be evaluated as
True or False.
• Value if True – The value to return if the logical test or logical
expression evaluates to TRUE.
• Value if False – The value to return if the logical test or logical
expression evaluates to FALSE.
The table below shows the formula to display “Passed” if the student’s average is 75 and
above, and “Failed” if the average is below 75. Since the cell reference H2 has the value
of 73.6, “Failed” will be displayed. But not in the case of cell references H3 and H4, since
their values are higher than 75 “Passed” will be displayed.

Microsoft PowerPoint
Microsoft PowerPoint
Microsoft PowerPoint is a powerful presentation software that helps you produce an effective
presentation in the form of on-screen slides. It provides hyperlinks and several animation styles such as
Entrance, Emphasis, Exit and Motion Paths. Animation and hyperlinks are great tools in making a
presentation more dynamic.

Imaging and Design for the Online
Environment (Part I)
Computer graphics are visual representations of data made on a computer and is displayed on a
computer screen or monitor. They can be a single image or series of images called video. They can be
anything on computers such as photographs, drawings or movies that does not involve sound.
Layout is the arrangement of graphic elements on a page. An effective graphics and layout contribute
to the efficiency of website. Hence, you must begin learning the basic principles of graphics and layout
before creating your own graphic design which you can integrate on the online environment.

Principles of Graphics and Layout
Across disciplines, the following principles are followed to standardized image creation and
manipulation using any graphics software. It will help you create layouts and design web pages
compliant with protocols.
1. Balance – It describes the placement of elements of equal weight on the page. The three types
of balance are symmetrical, asymmetrical, and radial.
Image source: https://en.wikipedia.org/wiki/File:Artistic_balance.png
2. Movement – It describes the flow of elements on the page. Visual elements guide the viewers’
eyes around the page.
3. Unity – the sense of oneness of the elements that creates balance and harmony.
4. Repetition – It describes the consistent and balanced repetition of a design or element.
An example is infographics that applied
repetition to the design. It repeatedly used callouts
with identical font size of inside texts.
5. Proximity – It describes the organization and relationship of the elements included in the
design.
6. Contrast – it is the combination of the opposing characteristics of an element like color, size,
thickness, and among others. It allows emphasis on key elements.
7. Emphasis - An area in the design that catches viewer’s attention. The area may appear different
in size, color, texture or shape.

Infographics
Information graphics or infographics are used to represent
information, statistical data, or knowledge in a graphical manner
usually done in a creative way to attract the viewer’s attention.
Infographics make complex data become more visually appealing to
an average user.
An infographic should have the following characteristics:
1. Thesis/Story. The subject and the main idea of your infographic must be clear.
2. Data. Data must be well-organized and supports the main idea.
3. Simplicity. (color, style, and illustrations). You must be able to create your own palette; your
style must be able to attract readers so as not to make your infographic full of text. Do not use
stock photos.
4. Sources. You must cite your sources so as to give credibility to your data.
5. Branding/Shareability. Your infographic must be creative and innovative.
The following websites will help you create infographic:

4. https://infogr.am/
Image File Formats
Since the introduction of graphics on the web., file formats also became an important aspect in the
design stage. The most common file formats are JPEG, GIF, BMP, TIFF, and PNG.
1. JPEG – Joint Photographic Experts Group. It is the most popular image format used on the web.
JPEG are very ‘lossy’ files where much of the information about the image is lost from original
state to keep the image file size small. JPEG files are used mostly by photographers, artists, graphic
designers, medical imaging specialists, art historians, and other groups because image quality and
color fidelity is important in the field.

2. GIF – Graphics Interchange Format. It is limited to the 8-bit palette with only 256 colors. GIF is
best used for diagrams, cartoons, and logos which use few colors and is the chosen format for
animation effects.
3. PNG – Portable Network Graphic. This file format is best with line art, text, and logo. It is capable
to display transparencies.
4. TIFF – Tagged Image File Format. It is considered as a high-quality image format, where all color
and data information are stored. However, it produces a very large file size and take huge disk
consumption.
Imaging and Design for the Online
Environment (Part II)
From the previous lesson, we’ve learned the following:
• Balance, movement, unity, repetition, proximity, contrast and emphasis composed the basic
principle of graphics and design.
• Balance deals with the visual weight of objects.
• Emphasis is the area designed to attract the viewer’s attention.
• Movement guides the viewer’s eye around the screen.
• Contrast is the combination of opposing characteristics of an element like color, size, thickness,
to allow emphasis on key elements.
• Infographic is also known as data visualization.
• For infographic to be effective, it must have the following: thesis, wellorganized data, simplicity
in color, style and vivid illustrations. It must contain reliable sources and must be creative for
public sharing.
• Common image file formats that are used for the web are JPG, GIF, TIFF, and PNG.
• JPEG is best used for photographs.
• GIF is best used for diagrams, cartoons, logos and animated graphics. It also limited with online
256 colors.
• TIFF is considered a high-quality image format, where all color and data information are stored.
• PNG is best with line art, text, and logo.

Principles and Basic Techniques of Image Manipulation
Whether you are using a free image manipulation program or purchased one, there are basic
techniques common to all image editing programs.

1. Cropping – It is a process of removing unwanted parts of the image, focusing only on the
subject. When cropping, one must always follow the Rule of Thirds to organize the image
composition.
2. Color Balance – In any image manipulating program, this command will allow you to make
changes in the mixture of colors in an image.
3. Adjusting Brightness and Contrast – This command is the most basic technique when
adjusting the image tone (highlights, shadows, and midtones).

4. Compression and Resizing – Compressing and Resizing an image is an important aspect
in image manipulation. Images to be uploaded on the web must be pf the standard resolution of
72 dpi (dots per inch) to maintain its image file size of 30-50 KB. If the image is for printing, set
the maximum resolution to 300 dpi at set its physical printing size in inches.

5. Color Blending – Use the different special effects buttons available in the different image
editing software. You can combine colors and commands that will give you a more dynamic image
result.
