Study Notes
Hardware Overview
- Hardware refers to the physical components of a computer that users interact with directly.
- Internal hardware is located within the computer's main box (system unit); external hardware is outside and connects via ports.
Types of Hardware
- Input Devices: Devices that allow users to input data into the computer, including keyboards, mice, scanners, cameras, headphones, microphones, and joysticks.
- Processing Devices: Responsible for calculations and managing operations, primarily the central processing unit (CPU) and memory.
- Output Devices: Present processed results to users, such as monitors, printers, speakers, and projectors.
- Storage Devices: Store and retrieve data, examples include hard drives, DVDs, and USB flash drives.
- Communications Devices: Enable electronic communication and information access; include modems and network adapters.
Software Overview
- Software encompasses all programs that instruct and control hardware during data processing activities.
Categories of Software
- Application Software: Designed for end-users to perform specific tasks; common examples include word processors and spreadsheets.
- System Software: Aids programmers and manages the overall computer system; includes operating systems and code editors.
System Concepts
- A system is a collection of interrelated components (people, machines, methods) working together to achieve specific objectives.
- System Analysis: The methodical process of defining, analyzing problems, and proposing solutions, akin to the scientific method in computing.
- General Systems Theory: Defines a system by its inputs, outputs, processing activities, feedback mechanisms, boundaries, and environmental context.
Information Systems
- An information system integrates hardware, software, infrastructure, and personnel to enhance an organization's planning, control, coordination, and decision-making capabilities.
- System Analysts are computer professionals tasked with developing and implementing applications, often playing a vital role in information systems.
