    Study Notes

    History of Operating Systems

    • First Generation (1940s): Computers operated without programming languages or operating systems.
    • Second Generation (1950s): Introduction of punch cards; General Motors developed the first operating systems for the IBM 701.
    • Batch Processing: Single-stream systems run one job at a time, with programs submitted in batches.
    • Third Generation (1960s): Emergence of multiprogramming, allowing several jobs to run concurrently and increasing resource utilization.
    • Time-Sharing Technique: Enabled multiple interactive users on a single computer, requiring quick response times to maintain productivity.
    • Fourth Generation (1970s): Introduction of LSI circuits and microprocessors led to personal computers gaining power comparable to mainframes.

    Classification of Operating Systems

    • Multi-user: Systems accessible to multiple users, allowing concurrent operation; time-sharing is a key feature.
    • Multiprocessing: Supports two or more CPUs within a single system, enhancing processing power.
    • Multitasking: Enables users to run multiple tasks simultaneously, tracking the state of each task without data loss.
    • Multithreading: Allows a single process to manage multiple threads of execution, optimizing resource use without multiple copies running.
    • Real-Time: Designed for applications that require immediate data processing with strict timing constraints.

    Notable Operating Systems

    • Mac OS: Renowned for its beautiful design and ease of use; requires an Apple computer. Suitable for users seeking a stylish and high-quality experience.
    • Linux: A free, Unix-like operating system with a focus on community collaboration. Offers various distributions tailored for different user needs, from beginners to enterprise solutions.

    Programming Languages Overview

    • Imperative vs. Declarative: Different programming paradigms influence how languages are structured, affecting syntax and semantics.
    • Procedural Programming: Focuses on executing a sequence of statements; characterized by multiple variables and heavy looping.
    • Functional Programming: Emphasizes return values and avoids side effects; encourages the use of recursive functions over loops.

    Python Programming Language

    • Created by Guido van Rossum and released in 1991; known for its simple, readable syntax akin to English.
    • Multi-platform compatibility allows use on Windows, Mac, Linux, Raspberry Pi, and more.
    • Versatile applications: web development, software development, mathematics, and system scripting.
    • Syntax designed for readability; commands finish with new lines rather than semicolons or parentheses.
    • Capable of rapid prototyping and robust application development, with capabilities for handling big data and complex computations.

    PHP 7 Features

    • Significantly faster than PHP 5.6.
    • Improved error handling and support for stricter type declarations.
    • Introduced new operators, enhancing the programming experience.
