Role of Data, Information, Knowledge, and Conclusion/Decision in Information Management

• Information management processes raw data into insights for decision-making
• Raw facts, figures, and observations collected from various sources is component known as Data and serves as the foundation for information processing for analysis, reporting, and identifying trends
• Processed and structured data provides context and meaning, helping in understanding patterns, relationships and insights for monitoring business performance, identifying issues, and planning strategies
• Knowledge is the interpretation of information based on experience, expertise, and context, enabling deeper understanding and application of information for problem-solving, innovation, and optimizing operations
• Conclusion/Decision is the final outcome derived from knowledge to take action and leads to informed decision-making and policy setting for strategic planning,resource allocation, and business growth

Example in Business Context

• Data examples include sales figures for different products
• Monthly sales report showing which products are performing well, is an example of information
• Understanding that a specific product sells more during certain seasons is an example of knowledge
• An example conclusion is increasing production and marketing efforts for that product during peak seasons

Reasons for Using Computers

• Productivity, communication, and efficiency are enhanced by computers
• Digital documents reduce paper usage, and automation speeds up tasks, reducing manual labour

• Automated calculations and data processing reduce human errors, ensuring precision in financial, scientific, and business applications
• Computers provide consistent performance, store large amounts of data securely and operate with minimal downtime when properly maintained
• Geographical barriers are eliminated, remote work, online collaboration, and instant communication are enabled by internet and computers
• Worldwide connectivity is fostered through social media, web tools, and video-sharing platforms, enabling interactions

Advantages of Computers

• Operations are streamlined
• Information and resources are accessed easily
• Decision making is improved
• Innovation and advancements made easier
• Productivity is automated and increased
• Entertainment and Multimedia enhanced
• Storage created
• Accuracy increased
• Accessible and Assistant Technologies are increased

Information Processing Cycle

• The cycle includes Input, Processing, Storage, Output and Communication
• Raw data is entered into the system using input devices
• The computer processes input data by performing calculations, running software, or analysing information
• Processed data is saved for future access, either temporarily or permanently
• Useful format that processed information presented to the user
• Information is transmitted between devices, users, or systems over networks

Examples of Each Step Include

• Typing using a Keyboard, clicking with a Mouse, or Scanning documents, are all inputs
• CPU executing instructions, applying formulas in Excel, data sorting, AI algorithms analysing data, are all examples of processing
• Hard drives (HDD/SSD), RAM (temporary storage), cloud storage (Google Drive, OneDrive), databases, are all forms of storage
• A monitor (displaying results), printer (printing reports), speakers (audio output), projector (visual presentation) are forms of output
• Examples of communication are sending and receiving emails, video conferencing, file sharing and social media communications

Online Shopping as an Example of the Information Processing Cycle in Action

• The customer enters product details and payment information
• The system verifies payment, updates stock, and processes the order
• Order details are saved in the database for tracking
• A confirmation message is displayed, and an invoice is generated
• An order confirmation email is sent, and tracking details are shared with the courier

Factors Influencing Fish Tank Environment

• Sensors and a microprocessor are used to control conditions
• To keep the fish healthy, the temperature should be 25 °C and the oxygen content 20 ppm
• The tank has a heater and an oxygen inlet controlled by a valve
• Alarms are installed on the sensors if the oxygen or temperatures aren't at the desired levels

Hardware and Software Devices

• Keyboard uses text input, data entry and programming, it’s is fast, easy to use and widely available however it causes repetitive strain injuries (RSI) and requires physical space
• Mouse/Trackpad uses navigation, clicking, selecting and gaming it produces precise control and intuitive operation. It however need a flat surface and can wear over time
• Scanner uses Digitizing documents and images, it can produce high-quality digital copies and reduces paper use. It can be slow for bulk and file sizes can be la Microphone is a voice input, recording, is hand free hands-free and enables voice commands however background noise can interfere and requires good hardware
