- 1. INFORMATION AGE Science Technology and society
- 2. LESSON OBJECTIVES At the end of this lesson, the students should be able to: Define information age; Discuss the history of information age; and Understand the factors that need to be considered in checking website sources. INTRODUCTION Highly modernized, automated, data-driven, and technologically advanced -these best describe our society nowadays, as evidenced by how infor could be transferred or shared quickly. The information aged is defined as a "period starting in the last quarter of the 20th century when information became effortlessly accessible through publications and through the management of information by computers and computer networks." The information age is also called the Digital Age and the New Media Age because it was associated with the development of computers.
- 3. JAMES R. MESSENGER ■ who proposed the Theory of Information Age in 1982, "the Information age is a true new aged based upon the interconnection of computers via telecommunications, with basis. Furthermore, the primary factors driving this new age forward are convenience and user friendliness which, in turn, will create user dependence."
- 4. As man evolved, information and its dissemination has also evolved in many ways.. Eventually, we no longer kept them to ourselves; instead, we share them and manage them in different means. Information got ahead of us. It started to grow at a rate we were unprepared to handle. Because of the abundance of information, it was difficult to collect and manage them starting in the 1960s and 1970s.
- 5. RICHARD WURMAN CALLED IT "INFORMATION ANXIETY." IN THE 1990S, INFORMATION BECAME THE CURRENCY IN THE BUSINESS WORLD. INFORMATION WAS THE PREFERRED MEDIUM OF EXCHANGE AND THE INFORMATION MANAGERS SERVED AS INFORMATION OFFICERS.
- 6. "TRUTHS OF THE INFORMATION AGE". ROBERT HARRIS DETAILED SOME FACTS ON THE INFORMATIO 1. Information must compet. 2. Newer is equated with truer. 3. Selection is a viewpoint. 4. The media sells what the culture busy. 5. The early word gets the perm. 6. You are what you eat and so is your brain. 7. Anything in great demand will be counterfeited. 8. Ideas are seen as controver . 9 . Undead information walks ever on. 10. Media presence creates the story. 11. The medium selects the message.
- 7. COMPUTER A computer is an electronic device that stores and processes data (information). It runs on a program that contains the exact, step-by-step directions to solve a problem (UShistory org, 2017)
- 8. 1. PERSONAL COMPUTER (PC) It is a single-user instrument, PCs were first known as microcomputers. since they were a complete computer but built on a smaller scale than the enormous system operated by most businesses. 2. DESKTOP COMPUTER It is described as a PC that is not designed for portability. The assumption with a desktop is that it will be set up in a permanent spot. A workstation is simply a desktop computer that has a more powerful processor, additional memory, and enhanced capabilities for performing special group of tasks, such as 3D graphics or game development
- 9. 3. LAPTOPS These are portable computers that integrate the essentials of a desktop computer in a battery- powered package, which are somewhat larger than a typical hardcover book. They are commonly called notebooks. 4. PERSONAL DIGITAL ASSISTANTS These are tightly integrated com usually have no keyboards but touch screen for user input. PDA typically smaller than a paperba lightweight, and battery-powered.
- 10. 5. Server It refers to a computer that has been improved to provide network services to other computers. Servers usually boast powerful processors, tons of memory, and large drivers. 6. MAINFRAMES These are huge computer systems that can fill an entire room. They are used es large firms to describe the large, machines that process millions of every day. The term "mainframe replaced by enterprise server. 7. WEARABLE COMPUTERS They involve materials that are usually integrated into cell phones, watches and other small objects or places. They perform common computer applications such as databases, email, multimedia, and schedulers.
- 11. THE WORLD WIDE WEB INTERNET Several historians trace the origin of the internet to Claude F. Shannon, an American Mathematicians who was considered as the "Father of Information Theory". He worked at Bell Laboratories and at age 32, he published a paper proposing that information can be quantitatively encoded as a sequence of ones and zeroes. The internet is a worldwide system of interconnected networks that facilitate data transmission among innumerable computers. It was developed during the 1970s by the Department of Defense. In case of an attack, military advisers suggested the advantage of being able to operate on one computer from another terminal In the early days, the Internet was used mainly by scientists to communicate with other scientists. The Internet remained under government control until 1984. (Rouse, 2014).
- 12. Sergey Brin and Larry Page, directors of a Stanford research project, built a research engine that listed results to reflect page popularity when they determined that the most popular results to frequently be the most usable. Google is now the world's most popular search engine, accepting more than 200 million queries daily One early problem faced by internet users was speed. Phone lines could only transmit information at a limited rate. The development of fiber optic cables allowed for billions of bits of information to be received every minute. Back then, new forms of communication were also introduced. Electronic mail, or email, was a suitable way to send a message to fellow workers, business partners, or friends. Message could be sent and received at the convenience of the individual..
- 13. A letter that took several days to arrive could be read in minutes, Internet service providers like America Online and CompuServe set up electronic chat rooms. These were open areas of cyberspace where interested parties could join in a conversation with perfect strangers. "Surfing the net" became a pastime in and of itself. Consequently, companies whose businesses are built on digitized information have become valuable and powerful in relatively short period of time; the current Information Age has spawned its own breed of wealthy influential brokers from Microsoft's Bill Gates to Apple's Steve Jobs to Facebook's Mark Zuckerberg. Nowadays, crimes in various forms are rampant because of the use of social media. Cyber bullying is an issue that poses alarm worldwide.
- 14. APPLICATIONS OF COMPUTERS SCIENCE AND RESEARCH One of the significant applications of computers for science and research is evident in the field of bioinformatics, Bioinformatics is the application it information technology to store, organize, and analyze was amount of biological data which is available in the forms of sequences and structures or proteins-the building blocks of organisms and nucleic acids-the information carrier. The human brain cannot store all the genetic sequences of organisms and this huge amount of data can only be stored, analyzes, and be used efficiently with the use of computers.
- 15. SWISS-PROT protein sequence database, was initiated in 1986. Some of the software tools which are handy in the analysis include: BLAST (used for comparing sequences) Annotator (an interactive genome analysis tool) GeneFinder (tool to identify coding regions and splice sites) The sequence information generated by the human genome research initiated in 1988, has now been stored as primary information source for future applications in medicine.
- 16. Moreover, from the pharmaceutical industry's point of view, bioinformatics is rational drug discovery. Molecular modelling, which requires a lot of calculations, has become faster due to the advances in computer processors and its architecture (Madan,n.d). In plant biotechnology, bioinformatics is found to be useful in the areas of identifying diseases genes and designing plants with high nutrition value (Madan, n.d.).
- 17. HOW TO CHECK THE RELIABILITY WEB SOURCES The internet contains a vast collection of highly valuable information but it may a unreliable, biased information that mislead people. Who is the author of the article/site? -How to find out? Look for an "About" or "More About the Author" link at the top, bottom, or sidebar of the web page. If no information about the author(s) of the page is provided, be suspicious. One can also visit the university library and seek help from librarians as they are knowledgeable and in the library has a rich collection of online library resources that are very useful for academic and research purposes.
- 18. SUMMARY Therefore, we need to carefully check our mo before disseminating information and we also need to verify information before believing and using and sharing them.
