    Study Notes

    Computer Basics

    • A computer can perform both computations and logical decisions.
    • Common components of computer hardware include keyboard, mouse, and CD-ROM; compilers are not hardware.
    • The Arithmetic and Logic Unit (ALU) is responsible for arithmetic calculations and logic decisions.

    Programming Languages

    • C is considered a high-level programming language, developed by Dennis Ritchie.
    • Java, a versatile language, is primarily used for large-scale enterprise applications.
    • Object-oriented programming promotes reusable software components.

    Operating Systems and Functions

    • Operating systems manage transitions between jobs and oversee computer resources.
    • Batch processing systems do not perform multiple tasks simultaneously; they process jobs in batches.

    Programming Concepts

    • Multitasking refers to running multiple activities in parallel within a program.
    • The C Standard Library provides pre-written functions for common programming tasks.
    • Structured programming encourages clear and modular coding.

    Computer Architecture

    • CPU (Central Processing Unit) supervises and coordinates other computer sections.
    • Secondary storage units, such as hard drives, store data long-term.

    Internet and Networking

    • The World Wide Web is primarily used to view multimedia documents.
    • Packet switching allows multiple users to send and receive data concurrently on the Internet without centralized control.

    True/False Facts

    • A computer’s primary role is to perform computations and logical decisions (True).
    • Secondary storage is slower than primary memory (False).
    • The C programming language is designed to be hardware-independent (False).

    Fill in the Blanks Concepts

    • Computer processes data via programs, using an input unit to gather data from peripherals.
    • Machine languages consist of strings of numbers providing specific instructions.
    • Functions in C perform specific tasks within a program.
    • Objects in object-oriented programming represent reusable software components.
    • Hardware capacity doubles approximately every year or two, indicating rapid technological advancements.
    • Distributed computing refers to computing spread across multiple networks.

    Additional Notes

    • Java was created to support dynamic and interactive web content.
    • The ALU is integral for performing arithmetic calculations and logical decisions within a computer.
