    Study Notes

    Information Systems Defined

    • An information system is a collection of interconnected elements that gather (input), process, store, and share data and information.
    • It also incorporates a feedback system to monitor and adjust its operations to achieve its desired goals and objectives.

    Types of Feedback

    • User Feedback: Systems can collect user feedback through surveys, forms, or online reviews to gauge user experience, satisfaction, and potential areas for improvement.

    • Error Reporting: Systems can implement feedback mechanisms to capture and report errors or exceptions. This information helps pinpoint root causes, troubleshoot problems, and implement corrective measures to prevent future occurrences.

    Computer-Based Information Systems (CBIS)

    • A CBIS is a complete system comprised of hardware, software, databases, networks, personnel, and procedures.

    People and Procedures

    • Systems can enhance job satisfaction and improve worker productivity.
    • Information systems personnel are responsible for managing, running, programming, and maintaining the system.
    • Procedures within a CBIS define steps for specific tasks, such as entering customer orders or paying supplier invoices.
    • Following procedures is crucial for operating, maintaining, and securing the system.
    • User authentication procedures outline the steps for users to log in securely, typically involving identifying information and passwords.

    Virtual Reality

    • Virtual reality (VR) technology creates a computer-generated environment that simulates a 3D world and blocks out the physical surroundings.
    • Users typically wear VR headsets, gloves, and other devices to experience and interact with this digital environment.
    • VR is applied in gaming, education, and military training.

    Augmented Reality

    • Augmented reality (AR) overlays digital content onto the real world, enhancing the user's environment by providing contextually relevant information.
    • Examples of AR include Snapchat filters, IKEA Place, Pokémon GO, and new employee training videos.

    Computer System Types

    • Single-user computers are portable or non-portable (stationary).
    • Portable computers include wearable computers (like fitness trackers and smartwatches), smartphones, laptops, and tablets.
    • Non-portable computers include desktop computers.
    • Multiple-user computers include servers, mainframes, and supercomputers.

    Anatomy of a Computer

    • Hardware components perform input, processing, data storage, and output.
    • The Central Processing Unit (CPU) sequences and executes instructions.

    Read Only Memory (ROM)

    • ROM is nonvolatile, providing permanent storage for data and instructions.
    • ROM chips store essential programming for starting up a computer.
    • ROM chips were used in gaming system cartridges (e.g., Gameboy).

    Secondary Data Storage Devices

    • Secondary storage devices store large amounts of data and programs more permanently than memory.
    • They are nonvolatile, have greater capacity, and are cheaper than memory.
    • Most common forms of secondary storage include magnetic devices (hard disk drives), optical devices (CDs, DVDs, Blu-ray discs), and solid state devices (SSDs, USB memory sticks).

    Magnetic Secondary Storage Devices

    • Magnetic tape is a type of sequential secondary storage medium primarily for storing backups and archives.
    • Magnetic tapes are cost-effective per gigabyte, and have a lifespan of 10-20 years under proper conditions.

    Virtual Server

    • Virtualization logically divides the resources of a physical server to create multiple logical servers.
    • Each logical server acts as its own dedicated machine.

    Data Center

    • A data center is a climate and access-controlled building that houses the computer hardware that delivers an organization's data and information services.
    • Efficient data center operation considers reducing energy use (especially for cooling), and location with milder climates, lower energy rates, and land costs.

    Grid Computing

    • A collection of computers working together to solve common problems.
    • The Large Hadron Collider uses grid computing with 170 computing centers from 42 countries.
    • Volunteer computing, like the IBM World Community Grid app, allows individuals to contribute computing power to scientific research.

    Main Memory

    • Provides the CPU with a temporary working storage area for programs and data.
    • Delivers data and instructions to the CPU rapidly.
    • Also known as Random Access Memory (RAM).
    • RAM is temporary and volatile, meaning data is lost when the computer is turned off.

    Cache Memory

    • High-speed memory that the processor can access faster than main memory.
    • Located on or near the CPU chip.

    Types of Memory

    • Primary Storage: Used to hold data that the computer is currently using.
      • RAM
      • Cache Memory
    • Secondary Storage: Used to store data long-term.
      • Hard disks
      • Solid-state drives (SSDs)
      • Optical disks
      • Flash drives

    How Decoding Works? An Example

    • The Control Unit decodes instructions by generating signals to coordinate operations.

    Processor

    • Clock speed, often measured in gigahertz (GHz), indicates the number of cycles per second the processor can perform.
    • Modern computers typically operate in the 1 to 4 GHz range.

    Processor Architectures

    • x86: Predominantly used in desktop computers. Main manufacturers include Intel and AMD.
    • ARM: Primarily used in mobile devices due to its energy efficiency. ARM licenses its designs to chip manufacturers. Examples of ARM-based processors include Qualcomm Snapdragon and Apple M1.

    Haptic Technology

    • Adds a new dimension to user interfaces by replicating tactile sensations.
    • Applications include smartphones, VR gloves, and gaming controllers.

    Computer System Types

    • General-purpose computers: Desktops, laptops, and servers designed for a variety of tasks.
    • Special-purpose computers: Computers designed for specific functions, such as POS systems, medical imaging devices, aircraft computers, and ATMs.
