Introduction to Information System
An Information System is a combination of people, hardware, software, data, and procedures used to collect, process, store, and distribute information. It helps organizations and individuals in decision making, planning, and control. Examples include school management systems, banking systems, and railway reservation systems. In education, information systems help in managing student records, attendance, and results. In digital literacy, students learn how information systems work and how to use them efficiently. Information systems increase speed, accuracy, and efficiency of work. They reduce manual effort and save time. Proper use of information systems improves productivity and supports smooth functioning of institutions and organizations.

Information Representation
Information representation refers to the way information is shown or presented so that it can be easily understood. Information can be represented using text, numbers, tables, charts, graphs, images, and symbols. In digital systems, information is stored in binary form using 0 and 1. For users, information is displayed in readable formats like documents, reports, and dashboards. Good representation makes information clear and meaningful. Students understand concepts better when information is presented visually along with text. In digital literacy, learning how to represent information properly helps in communication and presentation skills. Proper information representation avoids confusion and helps in quick understanding and decision making.

Digital Media
Digital media refers to content created, stored, and shared in digital form using electronic devices. Examples include text files, images, audio, video, graphics, and animations. Digital media is widely used in education, entertainment, advertising, and communication. Students use digital media for online classes, presentations, and projects. Digital media is easy to store, edit, copy, and share through the internet. In digital literacy, understanding digital media helps users create and consume content responsibly. Digital media makes learning interactive and interesting. It also helps in spreading information quickly to a large audience. Proper use of digital media improves communication and creativity.
- Image
An image is a visual representation of an object, person, or scene. In digital form, images are made using pixels and are stored in formats like JPEG and PNG. Images are used in books, websites, advertisements, and educational materials. Students use images to understand concepts better and make presentations attractive. In digital literacy, users learn how to view, edit, and share images safely. Images help in visual learning and memory. They communicate ideas quickly without using many words. However, images should be used responsibly and verified to avoid misinformation. Proper use of images improves understanding and visual communication.
- Graphics
Graphics are visual elements like drawings, diagrams, charts, and illustrations created using computer software. Graphics help in presenting complex information in a simple and attractive way. Examples include graphs in economics, flowcharts in computer studies, and diagrams in science. In digital literacy, students learn to create and understand graphics using tools like presentation and design software. Graphics improve clarity and attention. They help in comparing data and explaining ideas effectively. Good graphics save time and improve communication. They are widely used in education, business reports, websites, and digital advertisements to make information more appealing and understandable.
- Animation
Animation is the technique of showing moving images by displaying a series of pictures rapidly. In digital media, animation is created using computer software. Animation is used in cartoons, educational videos, advertisements, and games. In education, animation helps students understand difficult concepts easily, especially in science and technology subjects. In digital literacy, animation makes learning interactive and engaging. It captures attention and improves interest. Animation explains processes step by step and improves memory. However, animation should be used meaningfully and not only for decoration. Proper use of animation improves visual learning and communication.
- Audio
Audio refers to sound that is recorded and stored in digital form. Examples include music, speech, podcasts, and sound effects. Audio is used in education, entertainment, communication, and online learning. Students use audio for listening lessons, language learning, and lectures. In digital literacy, users learn how to play, record, and share audio files. Audio helps in improving listening skills and understanding. It is useful for people who prefer auditory learning. Audio content can be accessed anytime and anywhere. Proper use of audio improves communication, learning experience, and accessibility of information.
- Video
Video is a digital media that combines images, audio, and motion. Videos are widely used in education, entertainment, news, and social media. Students learn concepts easily through video lectures and tutorials. In digital literacy, video helps in visual and practical learning. Videos explain real life situations and processes clearly. They are engaging and easy to understand. Videos can be recorded, edited, and shared easily using digital devices. However, users should verify video content to avoid misinformation. Proper use of videos improves learning, communication, and awareness in the digital world.
