    Study Notes

    Computing Platform

    • Fundamental hardware and software infrastructure supporting software applications.
    • Logic operations are jobs expressed in a number of steps to achieve a defined goal.

    Theory of Computation

    • Focuses on understanding how computers solve problems and handle information.
    • Investigates the limits and capabilities of computer systems.
    • Aims to develop new algorithms and computational models.

    Capabilities and Limitations of Humans

    • Capabilities:
      • Machines recognize and process multiple languages to perform useful tasks based on given instructions.
    • Limitations:
      • Human factors causing errors include physical, psychological, intellectual, environmental, and social factors.

    Capabilities and Limitations of Computers

    • Capabilities:
      • Self-directing with abilities to store, retrieve information, perform mathematical operations, and solve complex formulas with high precision.
    • Limitations:
      • Computers can only execute pre-programmed tasks, cannot think independently, and cannot correct input data errors.

    Branches of the Theory of Computation

    • Encompasses three key areas:
      • Automata Theory
      • Computability Theory
      • Complexity Theory

    Automata Theory

    • Founded by Alan Turing, recognized as the father of modern computer science.
    • Studies abstract machines like Turing machines, even before physical computers existed.

    Computer Architecture

    • Model of Computation: Defines allowable operations and their costs.
    • Algorithms: Step-by-step instructions for computer processing.
    • Types of Computer Architecture:
      • Van Neumann Architecture: Single memory for both data and instructions.
      • Harvard Architecture: Separate storage for data and instructions.
      • Modified Harvard Architecture: Combination of Van Neumann and Harvard architectures.
      • RISC and CISC: Different architectures for handling instructions.

    Components of Computer Architecture

    • CPU: Executes and manages data.
    • Memory Hierarchy: Includes cache, RAM, and storage devices.
    • I/O System: Facilitates communication between computers and external devices (e.g., keyboards, printers).
    • Storage Architecture: Manages how data is stored and retrieved.
    • Instruction Pipelining: Breaks down instruction execution into stages.
    • Parallel Processing: Divides tasks into subtasks for concurrent execution.

    Cloud Computing

    • Enables access to applications and database resources via the Internet.
    • Allows configuration and customization of applications from anywhere.
    • Deployment Models:
      • Public Cloud: General access, less secure.
      • Private Cloud: Limited to organizational access, more secure.
      • Hybrid Cloud: Combination of public and private access.
      • Community Cloud: Shared access among a group of organizations.

    Cloud Service Models

    • Infrastructure as a Service (IaaS): Offers control over infrastructure.
    • Platform as a Service (PaaS): Provides a platform for building applications.
    • Software as a Service (SaaS): Delivers complete software applications online.

    Advantages & Disadvantages of Cloud Computing

    • Provides flexibility and remote accessibility but may involve concerns about security and control depending on the model chosen.
