Study Notes
Introduction to Systems
- A system is a group of elements working together to achieve an objective
- Organizations, departments, and firms are examples of systems
- Basic system elements include objectives, control mechanisms, input, output, and transformation
- Input resources are transformed into output resources
- Example: human body systems, automobile inventory management
System Types
- Super system contains many subsystems
- Physical systems originate from tangible elements (e.g., business firms, equipment)
- Conceptual systems use non-physical resources (e.g., data, ideas, models)
System View
- The way we look at an issue, problem, or event in a system context
- Benefits for managers include understanding structural and functional complexity
Types of Systems
- Open-loop systems have no control mechanisms, automatically generate reports (e.g., electric hand dryer)
- Closed-loop systems have control mechanisms, feedback loops, and objectives (e.g., budget presentation with feedback)
Organization as Systems
- Most organizations are open systems
- Systems are designed to accomplish goals using people and resources
- Systems are composed of interconnected, specialized subsystems
Information Technology Basics
- Hardware refers to physical components (e.g., printer, monitor, speakers)
- Software refers to instructions for hardware (e.g., operating systems, applications)
- System unit is the case containing computer components (e.g., power supply, processor)
- Different system unit types exist (e.g., desktops, laptops, tablets)
System Unit Components
- Power supply, processor, memory, storage, and expansion cards comprise the system unit.
- Inside and outside the case protect computer components from damage
System Software
- Operating systems manage hardware and software (e.g., Windows, macOS)
- Device drivers control specific hardware components
- Diagnostics tools help identify and troubleshoot hardware problems
Application Software
- Application software allows users to accomplish tasks (e.g., word processing, web browsing)
- Applications act as an intermediary between users and operating systems
Memory
- Memory stores data, instructions, and information
- Volatile memory (RAM) loses data when power is off
- Non-volatile memory (ROM, flash memory) retains data without power
- Memory types include RAM, ROM, flash memory, and cache memory
Processing
- The processor (CPU) is the brain of the computer, executing instructions.
- Multicore processors contain multiple processing units for speed.
- Parallel processing allows computers to divide tasks across multiple cores or processors
Input and Output Devices
- Input devices accept data/instructions from users
- Output devices display or transmit results to users
- Types of input and output devices include keyboards, mice, monitors, printers, speakers
Storage Devices
- Storage devices store data permanently
- Hard disks use magnetic platters
- Solid-state drives (SSDs) use flash memory
- Different types of storage devices exist (e.g., hard disks, SSDs, USB drives)
Storage Devices Details
- Data storage devices record, retrieve, or transform data to/from storage media
- Hard disks store data using magnetic storage on platters
- SSDs utilize flash memory for faster storage access
- Flash memory is non-volatile and holds data even when power is off
System View & User View
- System view explains how the computer system works
- User view describes how a user interacts with the computer system
Utility Programs
- Specialized programs help with tasks such as troubleshooting and optimization, diagnostics, and antivirus programs
Internet Evolution
- The Internet is a global network connecting computer users worldwide
- The World Wide Web (WWW) is a system of interconnected documents (webpages)
World Wide Web (WWW)
- A collection of interconnected documents (webpages)
- Web browsers enable users to access and navigate webpages
- Web servers host webpages on the internet
Uniform Resource Locators (URLs)
- Globally unique addresses of resources on the WWW
- URLs enable users to access specific webpages
Data Modeling
- Data modeling is the process of creating a visual representation of data
- Data models help organize and understand data in a system
- Data dictionaries describe the structure and content of data in a system
Validation
- Techniques to ensure data accuracy
- Checking data for errors is critical
File Organization
- Data is organized into databases for efficient retrieval and management
Database Management Systems (DBMS)
- Software for managing databases
- Data management tools (DBMS) include functions to create, edit, and query databases
Application Software
- Programs designed for various purposes (e.g., word processing, accounting, gaming)
- Programs are categorized by roles they execute or by functions (e.g., processing data, communicating, gaming)
User Interface Types
- User interface (UI) defines communication between users and the computer systems
- Examples of UI types include command languages, menus, and graphical user interfaces (GUI)
- Different UI types offer varying ways for users to interact efficiently (e.g., GUI)
Operating System
- Operating Systems (OS) control hardware/software interaction
- Operating Systems (OS) are also responsible for managing resources of computers
