    Study Notes

    History of IT

    • IT is the use of computers and networking technologies to store, process, and retrieve information.
    • IT investments, including computers, networks, software, and employees, are one of the largest expenses for most organizations.
    • The field of IT emerged in the 1990s with the popularization of computers and the use of the Internet to connect them.
    • The network effect refers to the increasing benefit of a network as more members join.
    • The invention of the World Wide Web enabled information sharing on a global scale.
    • The Internet connects local area networks (LANs) within buildings to wide area networks (WANs) that span larger geographical areas.
    • Artificial intelligence (AI) aims to mimic human intelligence to perform tasks.
    • Machine learning is a type of AI where models learn from data patterns without human direction.
    • The development of machine learning has been driven by the increasing volume and complexity of data.
    • The first machine learning models were trained by humans in a process called supervised learning.
    • Self-supervised learning uses massive amounts of data to train models capable of generating predictions.
    • The GPT-3 language model has 175 billion parameters, trained on 45TB of text data.
    • The Llama 2 model has 7B, 13B, and 70B versions.

    Programming Languages

    • Procedural programming languages use precise steps to compose programs.
    • Object-oriented programming languages allow developers to create their own data types by organizing data and related functions into objects.
    • Scripting languages are used to automate tasks using existing application capabilities.
    • Markup languages specify how information should be displayed or interpreted.
    • JavaScript is increasingly used for both frontend and backend development.
    • Frameworks like React Native enable JavaScript development of mobile applications.

    Block-Based Programming

    • Block-based programming uses visual interfaces to represent programming concepts instead of traditional text-based coding.
    • Blockly from Google and Scratch from MIT labs are examples of block-based programming languages.
    • Block coding is a fun and interactive way to learn programming, ideal for beginners and children.

    Programming Basics

    • Many programming languages share core concepts.
