1. ICT DEVELOPMENT PRESENTED BY: Brenda Cadava Maria Ceceila Salvador Phenea Zamora Alliah Tabor Jean Castillo

2. The invention of the printing press 1440 century by Johannes Gutenberg,a goldsmith from the town of mainz in Germany,stands as the most significant event that launched a new social order. It would later on be known as the Gutenberg press. However , the history of printing stretches as far back as the third century when textiles became the first surface from where words were inscribed. By the fifth century, parts of East Asia used a technique called woodblock of wood,ink the wood,then transfer the images by pressing them into a surface if cloth or parchment. Is 1000s, Bi Sheng invented the movable type technology where each character or is carved or cast or hardened clay. A Korean monk named Baegun invented a metal movable type technology to produce a book titled Jikiji , which contained Buddhist texts collected from various monks and teachers.

3. The Industrial Revolution, which transpired from 1750 to 1850,brought unprecedented developments in agriculture,transportation , manufacturing,and technology.

4. Electronic Communication The rise of electronic communications took off from the invention of the telegraph in 1839 by Samuel Morse (1791-1872). The electrical telegraph’s system transmitted information via electric cables laid over several stations. Morse came up with a code composed of dots and dashes to signify words and numbers. After World War II, television even more popular and production of programs increase. In the Philippines, television was introduced in 1946 after James Lindenberg began assembling transmitters for the Bolinao Electronics Corporation.

5. From Analog to Digital These technological breakthrough have dramatically altered communications ang information dissemination.In 1943,the firts electronic computer was created.Like the television sets,it used the vacuum tubes technology.

6. Analog versus Digital Technology Analog and Digital are two types of signals. The difference between Analog and Digital is how the data is transmitted. Digital signals are transmitted as 1s and 0s, whereas analog signals are transmitted in waves.

7. The Global Villages As early as 1962, Marshall Mcluhan (1911-1980) already predicted that electronics would be crucial to the rise of the global Village. Mass media,travel,and electronic communications now make it easier for people to connect and communicate.

8. Computer history can be summed up in five generations base on when major technological developments in computer occurred.

9. First Generation(1940-1965) This period saw the use of vacuum tubes as processors. Vacuum tubes were large,taking a lot of space resulting in computers that were so huge,they almost always occupy a bug space in the room. Computers of this first generation were limited to single tasks. The idea of a multitasking computer was not yet a possibility then.

10. Second Generation (1957-1963) Transistors replaced vacuum tubes. In 1951,the Universal Automatic Computer(UNIVAC) was launched,making it the first commercial computer.

11. Third Generation (1964-1971) Third generation computers used integrated circuits and were considerably smaller than its predecessors. Transistors were miniatures and placed into silicon chips to provide accelerated processing capacity an efficiency.

12. Fourth Generation (1972-2010) From integrated circuits,computers are able to function using microprocessors which are computer processors on a silicon chips. In 1981, Intel developed the Intel 4004 chip which found all the vital components of a computer on a single chip. In 1984, apple introduced the Macintosh. It was during these times that the home computer more popular. They could now be linked together to form networks, thus ushering the development of the internet

13. Fifth Generation (2011-present) Fifth generation computers now employ artificial intelligence such as voice recognition. Computers can now understand spoken words and imitate human reasoning. Using various sensors, it can respond to its users mimicking the actions of human.

14. Joseph Carl Robnett Licklider Also known as J.C.R. , was an American computer scientist who was among the first people who conceived of the idea for a computer network.

15. Charles Babbage Was an English mathematician known for inventing the first mechanical and programmable computing device called “difference engine”.
