- Knowledge: Awareness and understanding of information, deriving insights
Types of Data
- Alphanumeric: Numbers, letters, and other characters
- Image data: Graphic images and pictures
- Audio data: Sound, noise, or tones
- Video data: Moving images or pictures
Characteristics of Valuable Information
- Accessible: Easy access for authorized users, in the right format and time
- Accurate: Error-free, avoid "garbage in, garbage out" (GIGO)
- Complete: Contains all important facts
- Economical: Cost-effective to produce, balancing value vs. cost
- Flexible: Usable for various purposes
- Relevant: Important to the decision maker
- Reliable: Trustworthy, depends on data collection methods

Information System (IS)
- Interrelated components that collect, store, process, and disseminate data and information
- Aims to meet objectives
Components of an Information System
- Input: Gathering and capturing raw data
- Processing: Transforming data into useful outputs
- Output: Production of information in documents and reports
- Feedback: System information used to adjust input or processing
Types of Information Systems
- Manual: Human-powered, e.g., investment analysts drawing charts
- Computer-Based: Using computers, e.g., Management Information Systems (MIS)
Management Information Systems (MIS)
- Combine hardware, software, databases, telecommunications, people, and procedures
- Collect, manipulate, store, and process data into actionable information
MIS Components
- Hardware: Computer equipment for input, processing, and output
- Software: Programs that govern computer operations
- Database: Organized collection of facts and information
- Telecommunications: Electronic transmission of signals
- Networks: Connect computers and equipment
