Information Communication Technologies Presented by : Benarbia Zakaria Introduction to Information and Communication Technologies (ICT) What is Information? is associated with data and knowledge, as information is data in context and with meaning attached is stimuli that has meaning in some context for its receiver. When information is entered into and stored in a computer, it is generally referred to as data What is Communication? The transmission of data from one computer to another, or from one device to another. A communications device, therefore, is any machine that assists data transmission. For example, modems, cables, and ports are all communications devices. What is Technology? The application of scientific knowledge to the practical aims of human life Is science or knowledge put into practical use to solve problems or invent useful tools. Is the collection of techniques, skills, methods, and processes used in the production of goods or services or in the accomplishment of objectives, such as scientific investigation. What is ICT? Information Communication Technologies ICT stands for Information and Communication Technologies. It encompasses devices and systems for processing, storing, and sharing information in multimedia formats and for various purposes. What is ICT? A good way to think about ICT is to think about all the ways digital technology is used to help individuals, businesses and organizations use information. ICT includes any product that will process information electronically ICT will store, retrieve, manipulate, transmit or receive information electronically. What do you think is an example of ICT? Anything that help you access, use, and share information is ICT: from computer, digital television, email, robots or household devices, such as electronic calendars, clocks, timers, to cell phones Defining ICT: Components Hardware Software Physical devices such as computers, smartphones, Applications and operating systems that enable servers, and networking equipment that form the users to perform specific tasks and manage tangible infrastructure of ICT systems. information efficiently. Networks Systems that connect devices and facilitate information sharing, including the internet, intranets, and wireless networks. ICT encompasses a broad spectrum of technologies that enable the processing, storage, and transmission of information. By integrating these components, ICT creates a powerful ecosystem that drives innovation and efficiency across various domains. Understanding the interplay between these elements is crucial for grasping the full potential of ICT in our digital age. Digital Devices: Types and Functions Device Type Key Features Primary Uses Desktop Computers High processing power, Office work, gaming, large storage content creation Laptops Portability, moderate Mobile computing, student power work Smartphones Compact, always Communication, mobile connected apps, social media Tablets Large touchscreens, Media consumption, light lightweight productivity Wearables Health sensors, Fitness tracking, quick notifications information access The diversity of digital devices caters to a wide range of user needs and preferences. From powerful workstations to ultra-portable smartwatches, each device type offers unique capabilities that enhance our digital interactions. Understanding the strengths and limitations of each device category is crucial for selecting the right tools for specific tasks and optimizing our digital experiences. Software System Software Application Software Utility Software Operating systems like Windows, Applications like word Utilities enhance the macOS, and Linux provide the processors, spreadsheets, and functionality of the system, foundation for other software to photo editing software are including antivirus programs, function, managing hardware designed for specific tasks and compression tools, and disk resources and user interactions. cater to user needs in various defragmenters, optimizing domains. performance and security. What is a Network? 1 Interconnected Devices A network is a group of interconnected devices, like computers, smartphones, and servers, that can share data and resources. 2 Communication Channels These devices communicate through various channels, including wired connections like Ethernet cables and wireless connections like Wi-Fi. 3 Shared Resources Networks allow devices to access shared resources, such as printers, files, and internet connections. ICT's Impact Across Sectors Business E-commerce platforms and customer relationship management (CRM) systems revolutionize how companies operate and interact with customers. Education Learning Management Systems and video conferencing enable remote and interactive learning experiences. Healthcare Telemedicine and health information systems improve patient care and data management. Government E-services and smart city initiatives enhance public services and urban management. What is the impact of ICT on the information centers? ICT made information creation in digital format possible. ICT made online access and file transfer possible ICT made networking and sharing of information resources possible Advantages and Disadvantages of ICT Advantages Disadvantages Time saving Cost for charging, credit and mobile phone Receive information faster and timely Loss of mobile phone Enables and facilitates communication Educational and literacy barriers of usage Find people Information breakdown Organize transport, inputs, workforce Fraud via treacherous calls Safer and easier money transfer
