3. Lesson Objectives:
At the end of this lesson, the students should be able to:
Define Information Age;
Discuss the history of Information Age; and
Understanding the factors that need to be considered in
checking website sources.
4. Introduction
Highly modernized, automated, data-driven, and technologically advanced
this best describe our society nowadays, as evidenced by how our society
have been influenced tremendously such as communication, economics,
industry, health, and the environment. Despite our gains due to the
growing development of information technology, the rapid upgrade of
information also has disadvantages. This lesson will discuss the history
and impact of technological advancements to society.
Life is accompanied by endless transmission of information that takes
place within and outside the human body.
Webster’s Encyclopedic Unbridged Dictionary - Information is
“knowledge communicated or obtained concerning a specific fact or
circumstance.”
5. Information Age
Period starting in the last quarter of the 20th century when
information became effortless accessible through publications
and through the management of information by computers and
computer network.
The Information Age is true new age based upon the
Interconnection of computers via telecommunications, with
these information systems operating on both a real-time and as-
needed basis. Furthermore, the primary factors driving this new
age forward are convenience and user-friendliness which, in
turn, will create user dependence (Messenger, J.R., Theory of
Information Age.1982).

8. “Truths of the Information Age”, Some facts on the Information Age by
Robert Harris.
1. Information must compete.
2. Newer us equated with truer.
3. Selection is a viewpoint.
4. The media sells what the culture buys.
5. The early word gets the perm.
6. You are what you eat and so is your brain.
7. Anything is great demand will be counterfeited.
8. Ideas are seen as controversial.
9. Undead information walks ever on.
10. Media presence creates the story.
11. The medium selects the message.
12. The whole truth is pursuit.
9. Computer
Computers are among the most important contribution of
advances in the Information Age to society. A computer is an electronic
device that stores and processes data (information). It runs on a program
that contains the exact, step-by-step direction ls to solve a problem
(UShistory.org, 2017).
10. Types of Computer
1. Personal Computer (PC)
- It is the single-user instrument. Known as “microcomputers”
11. Types of Computer
2. Desktop Computer
- It is described as a PC that is not designed for portability.
12. Types of Computer
3. Laptops
- Portable computers that integrate the essentials of a desktop
computer in a battery-powered package. Commonly called
“notebooks”
13. Types of Computer
4. Personal Digital Assistants (PDAs)
- These are tightly integrated computers that usually have no
keyboards but rely on a touch screen for user input.
14. Types of Computer
5. Server
- It refers to a computer that has been improved to provide
network services to other computers.
15. Types of Computer
6. Mainframes
- They are used especially by large firms to describe the large,
expensive machines that process millions of transactions every day.
Although some supercomputers are single computer systems, most
comprise multiple, high performance, parallel computers woking as a
single system
16. Types of Computer
7. Wearable Computers
- They involve materials that are usually integrated into
cellphones, watches, and other small objects or places.
17. The World Wide Web (Internet)
• Claude E. Shannon – “Father of Information Theory”
• Internet – world wide system of interconnected networks that facilitates
data transmission among innumerable computers.
18. Applications of Computers in Science
Research
1. Bioinformatics
• Application of Information technology to store, organize, and
analyze vast amount of biological data.
2. SWISS-PORT protein sequence database
• initiated in 1996 It now has about 70,000 protein sequences from
more than 5,000 model organisms, a small fraction of all known
organisms
19. Applications of Computers in Science
Research
3. Rational drug discovery
• Potential targets for drug development are hypothesized from the
genome sequences. Molecular modeling, which requires a lot of
calculations, has become faster due to the advances in computer
processors and its architecture (Madan, n.d.).
4. Plant biotechnology
• Bioinformatics is found to be useful in the areas indentifiying
diseases resistance genes and designing plants with high nutrition
value (Madan, n.d.).
