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.
