2. What is information and Communications Technology? Information and communications technology (ICT) is a field of technology that deals with the control of communications processes including telecommunications, broadcast media, intelligent building management systems, audiovisual processing and transmission systems, and network-based control and monitoring tasks.

3. What is information and Communications Technology? Although there is no single, universal definition of ICT, the term is generally accepted to mean all devices, networking components, applications and systems that combined allow people and organizations (i.e., businesses, nonprofit agencies, governments and criminal enterprises) to interact in the digital world .

4. What is information and Communications Technology? The list of ICT components is exhaustive, and it continues to grow. Some components, such as computers and telephones, have existed for decades. Others, such as smartphones, digital TVs and robots, are more recent entries.

6. Brief History of Computer and its Development The history of Computer started from a simple device called Abacus .

7. Brief History of Computer and its Development It is the first computing device developed by the Chinese. The abacus is made up of beads or pebbles arranged in rows that represent values to facilitate calculations

8. Information and Communications Technology In 1617, inventors created a better calculating device, John Napier of Scotland invented a calculating device called Napier Bones. It can perform multiplication and division. It contains a set of 11 sticks, which were bones, and used by placing them side by side Napier Bones

9. Information and Communications Technology Napier Bones

10. Information and Communications Technology In 1642, Blaise Pascal, A French scientist, invented an adding machine called Pascal’s calculator. Instead of moving the beads manually, it worked mechanically and can add and subtract by means of rotating ten-toothed wheels and cogs Pascal Calculator

11. Information and Communications Technology Leibniz Calculator in 1671, Gottfried Leibniz, a German Mathematician, Modified the Pascal Calculator and developed a machine that could perform various calculations based on multiplication and Division

12. Information and Communications Technology Charles Babbage, a Scientist from England invented the Analytical Engine. A machine that can store numbers and perform arithmetic computations and logical operations. Analytical Engine

15. First Generation Computer First Generation Computer In 1946, ENIAC or Electronic Numerical Integrator and Calculator is the world’s first successful electronic computer ENIAC was developed and it was a starting point of the current generation of Computer

16. First Generation Computer It was the first general-purpose and programmable electronic computer. It utilized 18,000 vacuum tubes that worked simultaneously. The size of this machine requires a huge rooms. The storage capacity is quite small and could only process one program at a time

17. First Generation Computer ENIAC

18. Second Generation Computer Transistors were invented as a electronic components instead of Vacuum Tubes. Because a transistor is much smaller than a vacuum tube, This paved the way for second generation computers to become smaller compared with the first generation of computers.

19. Third Generation Computer The use of Integrated circuits or IC in its components is the defining characteristics of third generation computer. The main advantage of IC is not only its small size but also its superior performance and reliability compared to previous circuits.

20. Third Generation Computer This Generation of computers has far greater storage capacity and higher calculating speed than its predecessors. However, technological progress in miniaturization or the trend of producing even smaller devices and electronic products led to the development of smaller yet more powerful generation of computer

21. Fourth Generation Computers The Computers which we see around us belongs to this generation. A Microprocessor is a Single chip which is used in a computer for any arithmetical or logical function to be performed in any program.

22. Fourth Generation Computers Ted Hoff , an American electrical engineer, developed the first microprocessor, the Intel 4004 while working for intel corporation. With the use of microprocessor in the fourth generation computers, computers became very fast and efficient, combined with eh concept of Artificial intelligence

23. Fifth Generation Computer. Artificial Intelligence is the science and engineering of making intelligent machines by imitating human characteristics and behavior . some applications for fifth generation computers include robots that can interact with human

25. Data and Information DATA can be defined as a representation of facts , concepts or instructions in a formalized manner which should be suitable for communication, interpretation, or processing by humans or electronic machines . Data is represented with the help of characters such as alphabets, digits, or special characters and Idea.

26. Data and Information Data are simply facts or figures, When data are processed, interpreted, organized, structured or presented so as to make them meaningful or useful, they are called information .

27. Data Processing Data processing  is the conversion of data into usable and desired form . This conversion or “processing” is carried out using a predefined sequence of operations either manually or automatically . Most of the processing is done by using computers and thus done automatically. The output or “processed” data can be obtained in various forms.

28. Data Processing Input is the task where verified data is coded or converted into machine readable form so that it can be processed through a computer

29. Data Processing Processing is when the data is subjected to various means and methods of manipulation it can done Manually or automatically ,

30. Data Processing Output is the stage where processed information is transmitted to the user .

33. ICT in School ICT is constantly changing. It is important to keep up with how ICT is used at school, at home and at work At school, computer can help you: ∙ Research a topic; ∙ Record or organize information; ∙ Write a report; and ∙ Deliver a class presentation

34. ICT at home ∙ Find information ∙ Listen to music and watch movies; and ∙ Play games ∙ Communicate with friends and family;

35. ICT at work ∙ Maintain Schedules; ∙ Place orders and track sales; and ∙ Track products and workers. ∙ Create Documents;

36. Success is for ones who are busy looking for it. -Mark Robert E. De Jesus Thankyou Class! Goodluck, Be safe and God Bless.
