History of ICT Computer is any device which aids humans in performing ICT, or information and communications technology (or various kinds of computations or calculations. technologies), is the infrastructure and components that Three principal characteristics of computer: enable modern computing. It responds to a specific set of instructions in a well-defined Uses of ICT In Our Daily Lives manner. - Communication It can execute a pre-recorded list of instructions. - Job Opportunities It can quickly store and retrieve large amounts of data. - Education Applications of ICT (Computers) in Our Daily Lives - Socializing 1.

History of Computer: Basic Computing Periods Distance learning: students can access teaching materials Earliest Computers originally calculations were computed by from all over the world. humans, whose job title was computers. ICT facilitates the ability to perform ‘impossible’ These human computers were typically engaged in the experiments’ by using simulations. calculation of a mathematical expression. Creation of new more interesting jobs. The calculations of this period were specialized and Negative impacts of Information and Communication expensive, requiring years of training in mathematics.

The ENIAC The development of the World Wide Web(WWW) was begun was the first high-speed, digital computer capable of being in 1989 by Tim Berners-Lee and his colleagues at CERN, an reprogrammed to solve a full range of computing problems. international scientific organization based in Geneva, This computer was designed to be used by the U.S. Army for Switzerland. They created a protocol, HyperText Transfer artillery firing tables. Protocol (HTTP), which standardized communication between History of Computer: Generations of Computer servers and clients. Their text-based Web browser was made There are five generations of computer: available for general release in January 1992. First generation – 1946 to 1958 WEB 1.0 THE STATIC WEB Second generation – 1959 to 1964 The first version of the Web 1.0 invented by Tim Burners-Lee Third generation – 1965 to 1970 lasted a decade from 1990, often called the "Read-Only Web", Fourth generation – 1971 to Today was a place where content was consumed but not interacted Fifth generation – Today to future with. Websites were like digital brochures, providing a. The First Generation information but lacking the dynamic interactivity we associate The first computers used vacuum tubes for circuitry and with today's internet. magnetic drums for memory, and were often enormous, Things works in WEB 1.0 taking up entire rooms. First generation computers relied on machine language, the lowest-level programming language understood by computers, to perform operations, and they could only solve one problem at a time. Input was based on punched cards and paper tape, and output was displayed on printouts. b. The Second Generation Transistors replaced vacuum tubes and ushered in the second generation of computers. One transistor replaced the equivalent of 40 vacuum tubes. Allowing computers to become smaller, faster, cheaper, more energy-efficient and more reliable. Second-generation computers moved from cryptic binary machine language to symbolic Examples: UNIVAC III, RCA 501, Philco Transact S-2000, NCR 300 series, IBM 7030 Stretch, IBM 7070, 7080, 7090 series c. The Third Generation WEB 2.0 INTERACTIVE WEB The development of the integrated circuit was the hallmark of Web 2.0 is referred to as the Social web or the “read-write the third generation of computers. Transistors were web” by Dale Dougherty from 2000 to 2010. Web 2.0 miniaturized and placed on silicon chips, called brought about an explosion of user-generated content and semiconductors, which drastically increased the speed and social interaction. efficiency of computers. It could carry out instructions in In Web 2.0 you have a distribution relationship billionths of a second. Much smaller and cheaper compare to the second-generation computers. d. The Fourth Generation The microprocessor brought the fourth generation of computers, as thousands of integrated circuits were built onto a single silicon chip. Fourth generation computers also saw the development of GUIs, the mouse and handheld devices. e. The Fifth Generation Based on Artificial Intelligence (AI). Still in development. The use of parallel processing and superconductors is helping to make artificial intelligence a reality. The goal is to develop devices that respond to natural language input and are capable of learning and self-organization. WEB 3.0 INTELLIGENT WEB INTERNET Web 3.0 was devised by John Markoff of the New York Times Internet or “net” is the largest computer network in the world in 2006. is the envisioned next evolution of the internet, that connects billions of computer user. Internet comes from aiming to address concerns with Web 2.0 such as combination between “interconnection” and “network”. centralization and data control.

Geographic Location - rural areas and remote community often lack adequate broadband infrastructure, making internet access unreliable or unavailable. 2. Social Divide - Variations in ICT access within a country based on factors like income, education, age, and GENERATION COHORT Each generational cohort has experienced the evolution of The concept of generational cohorts was first proposed by the technology in different ways, leading to varied levels of digital German sociologist Karl Mannheim in his 1923 essay "The literacy, communication preferences, and attitudes toward Problem of Generations". He suggested that a generation technology. Understanding these generational differences is shares a common perspective because they live through the crucial where technological advancements influence same major events at similar stages of life, leading them to everything from work environments to education and social develop similar attitudes, values, and behaviors. interactions. William Strauss and Neil Howe generational theory in their 1991 book Generations: The History of America’s Future, 1584 to 2069, in this book, they identified and defined generational cohorts based on recurring cycles of generational traits and historical events. A generational cohort refers to a group of individuals who were born during the same period and share everyday historical, cultural, and societal experiences. Generational cohorts are often used to categorize and analyze people based on the era in which they were born INTERNATIONAL CONFLICT - is a complex issue, impacted by Silent Generation (1928 – 1945). These years span from the various factors, including generational differences. beginning of the Great Depression to the end of World War II. GENERATION GAP - is the difference in values, beliefs, and People born during this time are also sometimes called “Radio opinions that exist between members of varying generations.

BRIDGING THE GENERATION GAP 1. Facilitate Intergenerational Dialogue: Encourage platforms for discussion across generations. 2. Leverage Technology and Social Media: Engage all generations on digital platforms. 3. Collaborative Decision-Making: Ensure diverse generational representation in policy. 4. Focus on Common Values: Emphasize peace, security, and human welfare shared across generations. IMPORTANCE OF CROSS GENERATIONAL COLLABORATION - Diverse Perspectives. - Increased Innovation. - Enhanced Problem Solving. - Sustainable Solutions. ROLE OF TECHNOLOGY IN BRIDGING GENERATIONS DIGITAL PLATFORMS - Social media, online forums, and video conferencing tools facilitate communication and connection. E-LEARNING - Online courses and educational platforms provide opportunities for knowledge sharing and skill development across generations. VIRTUAL COLLABORATION - Project management tools and collaborative workplaces enable seamless teamwork, regardless of location or age. DIGITAL STORYTELLING - Using digital tools to share personal experiences and perspectives can foster understanding and bridge generational gaps. Managing international conflict requires a comprehensive approach that considers the perspectives of all generations. By embracing diversity, fostering understanding, and leveraging the power of technology, we can work together to create a more peaceful and harmonious world.
