1. EMPOWERMENT TECHNOLOGIES

2. Information and Communications Technology Today   Module 1 1 st Semester

3. At the end of this module I will understand development of the information and communication technology over the years and how it is used in many different learning situations. I will compare and contrast the differences of varied online platforms, sites, and content to best achieve specific objectives in different settings in daily living.

4. QUESTIONS: How many times have you checked your phone this morning? How many status updates have you posted in Facebook and Twitter today? Did you use the Internet for an hour after you woke up this morning? Do you follow a celebrity via his/her social media?

5. Do you think you are a DIGITAL NATIVES?

6. If you happen to be “guilty as charged” in most of these questions, chances are, you are a DIGITAL NATIVE . And chances are, from the moment you were born, You were surrounded by technology You are surrounded by ICT

7. Refers to the technologies, both hardware and software , that enable humans to communicate with one another. It is any form of technology that enables you to communicate. - Mobile Phones - Telephones - Internet Information and Communications Technology (ICT)

8. ICT in the Philippines

9. Philippines is dub as the “ ICT Hub of Asia” (BPO) According to the 2013 edition of Measuring the Information Society by the International Telecommunications there are 103 cellphones per 100 Filipinos. ICT in the Philippines

10. In data gathered by the Annual Survey of the Philippines Business and Industries, NSO, in 2010, the ICT industry shares 19.3% of the total population in the Philippines. ICT in the Philippines

11. To add these statistics, Time Magazine’s “The Selfiest Cities around the World” of 2013 places two cities from the Philippines in the Top 1 and Top 10 spots . This was conducted using Instagram. ICT in the Philippines

12. With these numbers, there is no doubt that the Philippines is one of the countries that benefits most of the ICT ICT in the Philippines

13. THE EVOLUTION OF ICT

14. The beginning of ICT can be traced back when humans started to use objects to communicate with one another. It is ascertained that ICT began along with the rise of humans. EVOLUTION OF ICT

15. FOUR PERIODS OF ICT PRE MECHANICAL PERIOD MECHANICAL PERIOD ELECTROMECHANICAL PERIOD ELECTRONIC PERIOD

16. THE PRE MECHANICAL PERIOD 3000 B.C. - 1450 A.D.

17. Writing and Alphabets - Communication. PRE MECHANICAL PERIOD First humans communicated only through speaking and picture drawings. 3000 B.C., the Sumerians in Mesopotamia (Southern Iraq today) devised cuneiform. Around 2000 B.C., Phoenicians created symbols The Greeks later adopted the Phoenician alphabet and added vowels. T he Romans gave the letters Latin names to create the alphabet we use today. CUNEIFORM PHOENICIAN ALPHABET

18. Paper and Pens – Input Technologies PRE MECHANICAL PERIOD Sumerians' input technology was a stylus that could scratch marks in wet clay. About 2600 B.C., the Egyptians write on the papyrus plant around 100 A.D., Chinese made paper from rags, on which modern-day papermaking is based

19. Books and Libraries - Permanent Storage Devices. PRE MECHANICAL PERIOD Religious leaders in Mesopotamia kept the earliest “ books” The Egyptians kept scrolls around 600 B.C., the Greeks began to fold sheets of papyrus vertically into leaves and bind them together

20. The First Numbering Systems PRE MECHANICAL PERIOD In the late stage of this period, humans started using the numerical system. This numerical system spread around the world gradually, enabling a simpler, faster , and more organized way to count. Numbers 1-9 as vertical lines N umber 10 as a U or circle N umber 100 as a coiled rope N umber 1,000 as a lotus blossom. Egyptian Numbering System

21. The First Calculators - The Abacus PRE MECHANICAL PERIOD Humans started to optimize and invent devices and techniques in counting. The most popular device created in this period is said to have come from China – the ABACUS. The Abacus is a manually operated device similar to the modern calculator. This was considered as the first device to process information. The Abacus

22. THE MECHANICAL PERIOD 1450 - 1840.

23. The machines driven by mechanical means such as steam and gears dominated information processing and calculation. This period also concentrated primarily on development of machines that will enhance calculation speed. Bridge between our Current period and Pre Mechanical period

24. The highlight of this period is the advent of the mechanical calculator called  Pascaline. Invented by the famous mathematician inventor Blaise Pascal along with Wilhelm Schickard . The Mechanical period Pascal’s Calculator / Pascaline. Note: Play the video >

25. Charles Babbage , a mathematician invented the Analytical Engine, which is considered the first programmable mechanical computer. This earned him as the “Father of Computers” The Mechanical period Charles Babbage (1792-1871), eccentric English mathematician Charles Babbage Engine

26. THE ELECTRO MECHANICAL PERIOD 1840 - 1940

27. The electromechanical period ushered in a new age in communications and information. The use of electricity for information handling and transfer bloomed. The need and the urgency to share information with one another in a faster yet reliable manner over long distances aroused. The information is coded in sounds of dots, spaces, and dashes over wired ( and eventually wireless) media. The Electromechanical Period

28. The Telegraph is considered the fist electrical communications device that transmit information. First invented by William Cooke and Sir Charles Wheatstone, the first working models used five magnetic needles that could be pointed around  sets of letters and numbers by using electric current.  The Electromechanical Period Telegraph

29. Then in 1844, an American inventor named Samuel Morse successfully introduced the first single-circuit telegraph, which gave rise to Morse Code. In 1876, Alexander Graham Bell was granted the patent for the telephone. The telephone converts sounds into electricity and enables the telephone network to transmit it over copper wires. The Electromechanical Period Samuel Morse Morse Code Alexander Graham Bell

30. THE ELECTRONIC PERIOD 1940 - Present

31. THE ELECTRONIC PERIOD This highlight on the advent of solid state devices or electronic devices. The four main events found in this period are: The Late Vacuum Tubes period T he Transistors period T he Integrated Circuits period T he Computer Processors period.  

32. THE ELECTRONIC PERIOD Vacuum tubes as their main logic elements. Punch cards to input and  externally  store data. Rotating magnetic drums for  internal  storage of data and programs Programs written in Machine language Assembly language Requires  a compiler . The Late Vacuum Tubes period (1951-1958) Vacuum tubes

33. THE ELECTRONIC PERIOD The transistor was invented in 1947. The electronic device with properties and functions similar to vacuum tubes , but it is lightweight and faster . The first full transistor was developed in 1957 and was faster than vacuum computers and was faster than vacuum computers.   The Transistors period (1959-1963) Transistors

34. THE ELECTRONIC PERIOD The Integrated Circuit (IC) is a device that is composed of a group of transistors and circuit elements compressed in a single package . The IC revolutionized the use of computers and electronic devices because circuits are integrated in a chip or a single package, limiting the distances between components, resulting in a faster operating speed. The Integrated Circuit period (1964-1979) Integrated Circuits

35. THE ELECTRONIC PERIOD Microprocessors that contained memory, logic, and control circuits (an entire  CPU = Central Processing Unit)  on a single chip. Which allowed for home-use  personal computers or PCs , like the Apple (II and Mac) and IBM PC. The Computer Processor period (1979- Present) Computer Processor
