Study Notes

Information Systems and Digital Trends

Course aims include exploring the impact of digital technologies on shaping lives and business opportunities and understanding information systems' organizational and managerial implications.
Digital technology, based on binary digits (0 and 1), is an information and communication technology (ICT).
A 'bit' is the smallest unit of information in computer memory.
A 'byte' is a sequence of 8 bits, representing a letter or symbol.
Digitalization transforms analog signals and physical objects into digital ones, enabling content viewing across various devices.
ASCII (American Standard Code for Information Interchange) table codifies 8-bit characters (e.g., A = 01000001).
Unicode is a coding system that supports a larger number of characters.
Various multiples of bytes exist (KB, MB, GB, TB).

Chapter 1 + 2: Definitions

Information systems (IS) comprise interrelated components that transform inputs into outputs to reach organizational objectives.
Information systems collect, process, store, and distribute information to support decision-making and control in an organization. Key components are ICTs, data, people, and processes.
Data is raw facts, typically about physical phenomena or business transactions.
Information comprises organized, processed, and meaningful data.
Knowledge is information understood, combined with opinion, to guide actions and decisions.
- Structured decisions have clear procedures, high certainty.
- Unstructured decisions are strategic, lack clear procedures, and high uncertainty.
Organizational levels (pyramid): executive (strategies), managerial (tactical), and operational (routine).
Different organizational types (e.g., professional, social, religious, governmental) have unique information system needs.
