OVERVIEW OF ICT INTRODUCTION TO ICT & WEB EVOLUTION LEARNING OBJECTIVES Define ICT Discuss clearly the Discuss correctly the merging of the two nuances of the three technologies: versions of the web Computer and Communications Technology Give examples of the different uses of ICT in everyday activities Appreciate the benefits of ICT 01 WHAT IS TECHNOLOGY? 02 03 WHAT IS ICT? COMPUTER TECHNOLOGY Let us define technology. Let us define Information and Let us discuss computer Communications Technology technology and its evolution 04 COMMUNICATIONS TECHNOLOGY 05 06 ICT IN OUR LIVES WEB EVOLUTION Let us discuss communications Let us discuss the applications of Let us discuss how the web technology as one of the ICT in the society technology evolve over the years technologies involved in the and its impact to online users. development of ICT TECHNOLOGY refers to the practical application of knowledge in a particular area (Merriam-webster) “Technology should improve your life… not become your life.” —BILLY COX WHAT IS ICT? Information and Communications Technology is a broader term for Information Technology - It refers to all computer and communications technologies enabling users to access, retrieve, store, transmit and manipulate information in a digital form. ICT IS A CONVERGENCE OF TWO TECHNOLOGIES COMPUTER COMMUNICATIONS TECHNOLOGY TECHNOLOGY Technology that consists of Technology that consists of people, processes, methods, people, processes, methods, computing devices, peripherals, electromagnetic devices, and and software use to speed up systems use for problem solving and increase communicating over long productivity.. distances COMPUTER TECHNOLOGY COMPUTER A computer is a programmable machine that accepts data (raw facts and figures) and processes or manipulates them into information that people can use.. EVOLUTION OF COMPUTER TECHNOLOGY FIRST GENERATION 1951-1957 - Vacuum Tubes SECOND GENERATION 1958-1963 - Transistors THIRD GENERATION 1964-1969 - Integrated Circuits FOURTH GENERATION 1970-1990 - Microprocessors FIFTH GENERATION 1991 - 2021 & beyond - Age of Connectivity EVOLUTION OF COMPUTER TECHNOLOGY 1 VACUUM TUBES DEVELOPED BY: Invented in 1904 by John Ambrose Fleming ADVANTAGES: Vacuum tubes were a basic component for electronics throughout the first half of the twentieth century, which saw the diffusion of radio, television, radar, sound reinforcement, sound recording and reproduction, large telephone networks, analog and digital computers, and industrial process control. SETBACKS: - large use of power - more heat = more downtime - more downtime = more expensive maintenance - huge size of computers - difficult to program = limited performance EVOLUTION OF COMPUTER TECHNOLOGY 2 TRANSISTORS DEVELOPED BY: American physicists John Bardeen, Walter Brattain, and William Shockley in 1947 ADVANTAGES: - less use of power - less heat = less downtime - less downtime = less expensive maintenance - smaller sized but faster processing time - more reliable SETBACKS: - The need for smaller and more reliable circuitry EVOLUTION OF COMPUTER TECHNOLOGY 3 INTEGRATED CIRCUITS An integrated circuit (IC or microchip) or monolithic integrated circuit is a set of electronic circuits on one small plate ("chip") of semiconductor material such as silicon. It is composed of millions of transistors ADVANTAGES: - size is compact - less cost to manufacture = less expensive - very fast processing time - more reliable SETBACKS: The need for a better circuitry EVOLUTION OF COMPUTER TECHNOLOGY 4 MICROPROCESSOR A specialized single chip developed for computer memory and logic.. A computer's central processing unit (CPU) is built on a single integrated circuit chip that greatly reduced the cost of processing power. ADVANTAGES: - single chip = reduced manufacturing cost - fewer electrical connections = more reliable - with smaller components = more smaller designs - faster and more powerful SETBACKS: None 5 AGE OF CONNECTIVITY Connected Generation” - The birth of ICT - All efforts are geared towards communication of computers in the information superhighway What is (tele)communication? It is the electronic transfer of data from one place to another TELECOMMUNICATIONS can TAKE PLACE through: WIRED TRANSMISSION WIRELESS TRANSMISSION communications take place using solid communications takes place without the use substances to transmit data - wired solid substances to transmit data - wireless transmission media such as coaxial cable, media send data through air or space using twisted pair, and fiber-optics cables, among infrared, radio, or microwave signals others SATELLITE TRANSMISSION communications take place using satellite to amplify radio or microwave signals and create a communication channel between a source and a receiver What is ONLINE? A term used to refer to a computing or information device connected to a network allowing transfer of information What is a NETWORK? It is a communications system connecting two or more computers; The internet is known as the the largest of all networks. WORLD WIDE WEB One of the subsets of the Internet that was developed by Sir Tim Berners-Lee. where information are interlinked by hypertext and are accessible over the Internet WEB TECHNOLOGY Web technology is the mechanism which enables two of computer devices to communicate over a network..

Making the web information INTELLIGENT. very limited content distribution YouTube, eZine Articles, Flickr and Currently, there is a communication gap between “shopping cart” applications where Facebook human web users and computerized applications. customers view products similar to Websites are responsive (i.e. the phone Computer applications cannot understand DATA in image does something when clicked). context. catalogs It is all about Semantic Web Technologies, Distributed Allows INTERACTION Retailers provide information to Sites uses LESS words, MORE images. Databases and Intelligent Applications customers about their products and Example: Semantic emails make emails both human how to purchase. and machine understandable, making it possible for machines to easily collect information on the relationships of the sender, the recipients, the email content, and the topics resulting to automation of common email-related tasks. APPLICATION OF ICT IN THE SOCIETY EDUCATION BUSINESS GOVERNMENT Research websites such as EBSCOHOST, Google E-commerce (buying and selling online) Use of ICT in Government Services and Scholar; Information is available anytime and such as Lazada, Amazon; Online Agencies such as SSS, LTO anywhere; Use of Learning Management banking and online payment Use of ICT to facilitate elections System such as Moodle, Google Classroom; (transactions such as payment, Use of ICT by Police in checking criminal Online Classes and Webinars; Distance Learning deposits are made without being records, monitoring traffic and crimes physically present in the establishment) on the streets (use of CCTV), patrolling Cash Value Card (such as HappyPlus, e-tap card)- the use of card as an equivalent for money MEDIA AND ENTERTAINMENT Business Intelligence Tools - software HEALTHCARE Online streaming of videos and music that can collect large data that can be - electronic health record (EHR) Video Games used by businesses for sales or - electronic prescribing Photo sharing market prediction - electronic-aided dispensing of Social networking sites (i.e. facebook, twitter) drugs in the hospitals Blogs - Imaging devices (e.g. Xrays, MRI, ultrasound) CREDITS: This presentation template was created by Slidesgo, including icons by Flaticon, and infographics & images by Freepik and illustrations by Stories THANKS!
