    Study Notes

    Fundamental Architecture of a Computer System

    • A computer system consists of input, processing, output, and storage (IPOS) components.

    IPO(S) Model

    • The IPO(S) Model represents the fundamental architecture of a computer system.
    • 'S' in the IPO(S) Model stands for Storage.
    • The IPO Model consists of Input, Processing, and Output components.
    • Storage is not a component of the IPO Model.

    Processing in the IPO Model

    • 'P' in the IPO Model represents Processing.
    • Processing involves actions taken on the input by the computer.

    Input Devices

    • Examples of input devices include keyboard, mouse, and scanner.

    Data Processing Operations

    • Basic data processing operations include data input, processing, and output.

    Output Devices

    • The purpose of output devices is to display or communicate the results of data processing.
    • Examples of output devices include monitor, printer, and speaker.

    Storage Devices

    • Random Access Memory (RAM) is used for short-term and temporary storage.

    Problem Solving with Computers

    • The role of computers in problem solving is to automate tasks and provide solutions.
    • Steps in the Problem Solving process include problem definition, algorithm design, and implementation.

    Algorithms

    • An algorithm is a well-defined procedure that takes some input and produces a corresponding output.
    • Characteristics of an algorithm include finiteness, definiteness, effectiveness, and language.

    Types of Computers

    • Stored program computers are capable of performing a variety of tasks due to accessing programs in memory.
    • Characteristics of stored program computers include flexibility and modularity.
    • Fixed program computers are limited to performing a single task.

    Primitive Data Types

    • In programming languages, primitive types are distinguished by their fixed size and format.
    • Examples of primitive types include integer, character, and boolean.

    Fixed Program Computers

    • Fixed program computers are limited to performing a single task.
    • The program is stored in read-only memory (ROM).

    Stored Program Computers vs. Fixed Program Computers

    • Stored program computers differ from fixed program computers in their ability to access and execute different programs.
