Study Notes
Information Systems Concepts
- Information: Processed and interpreted data that creates value by organizing relationships.
-
System: A group of components working together with inputs, processing, and outputs.
- Closed System: Does not interact with other systems.
- Open System: Interacts with other systems.
- Information Systems (IS): Combine people, hardware, software, communication networks, data resources, and policies to store, retrieve, transform, and distribute information within an organization.
Framework of Major Areas
- Focuses on:
- Foundation Concepts: Fundamental behaviors, technical business, and managerial concepts of IS.
- Information Technologies: Major concepts, developments, and management problems in IT.
- Business Applications: Major uses of IS for operations, management, and gaining competitive advantage.
- Development Process: Planning, developing, and implementing IS to meet business opportunities.
- Management Challenges: Effectively and ethically managing IT at the end-user, enterprise, and global business levels.
Components of Information Systems
-
Five Components:
- People: End users and IS specialists.
- Hardware: Machines and media.
- Software: Programs and procedures.
- Data: Includes data and knowledge databases.
- Networks: Communication channels.
- Data resources: Transformed into information products for end users through information processing.
- Information Processing: Includes input, processing, output, storage, and control.
Computer Generations
-
First Generation (1940s-1950s): Vacuum tubes, large and inefficient, basic arithmetic and logical operations.
- Examples: ENIAC, UNIVAC.
-
Second Generation (1950s-1960s): Transistors replaced vacuum tubes, smaller, more efficient, and reliable.
- Examples: IBM 7090
-
Third Generation (1960s-1970s): Integrated circuits (ICs) combined multiple transistors, leading to minicomputers and larger mainframes.
- Examples: DEC PDP 8.
-
Fourth Generation (1970s-1990s): Microprocessors integrated onto a single chip.
- Examples: Intel 4004, Apple II, IBM PC, Commodore 64.
- Fifth Generation (1990s-Present): Advancements in artificial intelligence (AI), quantum computing, and supercomputers.
Software
- Non-tangible component of a computer system.
- Characteristics:
- Intangible: Cannot be physically touched.
- Modifiable: Can be updated or modified.
- Dependent on Hardware: Requires hardware to function.
History of Software Development
-
Early Software (1950s-1960s): Single-purpose, hardware-dependent, and limited in storage and power.
- Examples: FORTRAN, assembly language.
-
Rise of Operating Systems (1970s): Introduced multitasking and resource management.
- Examples: Unix.
-
Personal Computing Era (1980s-Present): User-friendly interfaces, more complex software applications.
- Examples: Microsoft Windows, macOS.
Types of Computer Resources
Component of Computer Hardware
- Input Devices: Keyboard, mouse, scanner, microphone.
- Output Devices: Monitor, printer, speakers.
- Central Processing Unit (CPU): "Brain" of the computer.
- Memory: Stores data and instructions for access by the CPU.
- Storage Devices: Permanently store data. (Hard drives, solid-state drives)
- Network Interface Card (NIC): Enables internet connection.
- Motherboard: Main circuit board that connects all components.
- Power Supply Unit (PSU): Converts AC power to DC power for components.
Types of Software Resources
-
System Software: Manages hardware and provides a platform for other software to run.
- Examples: Operating systems, device drivers, firmware.
-
Application Software: Designed to perform specific tasks.
- Examples: Word processors, spreadsheets, web browsers, games, media players.
-
Utility Software: Specialized tool for system maintenance and optimization.
- Examples: Antivirus software, disk cleaners, backup tools.
Network Infrastructure
- Refers to the hardware and software that enable connectivity and communication between users, devices, apps, the internet, and more.
Supply Chain Management
- Strategic Coordination: Integration of business functions within an organization and its entire supply chain to optimize supply and demand management.
- Focus: Matching supply and demand as effectively and efficiently as possible.
- Key Issues: Outsourcing, procurement, managing suppliers and customer relationships, problem identification, and response.
Enterprise Resource Planning (ERP)
- Software that integrates business components, including supply chain processes, by sharing information and data among supply chain members.
