    Study Notes

    Moore's Law

    • States that the number of transistors in a dense integrated circuit doubles approximately every two years
    • Formulated by Gordon Moore, co-founder of Intel, in 1965
    • Has driven the exponential growth in computing power, enabling complex calculations and data processing at higher speeds
    • Has enabled the development of advanced technologies such as AI, VR, and big data analytics

    Pioneers in Computing

    Ada Lovelace (1815-1852)

    • Widely credited with creating the first computer program
    • Worked with Charles Babbage on his Analytical Engine and wrote an algorithm for it, making her the first computer programmer

    Alan Turing (1912-1954)

    • Made significant contributions to computer science and AI
    • Played a key role in cracking the Enigma code during World War II, using early computers and his concept of the Turing machine

    Steve Jobs (1955-2011)

    • Co-founder of Apple Inc.
    • Played a pivotal role in the development of iconic products like the iPhone and Macintosh

    Bill Gates (1955-present)

    • Co-founder of Microsoft
    • Played a crucial role in the development of the personal computer industry with products like MS-DOS and Windows

    Computer Components

    CPU (Central Processing Unit)

    • Primary component responsible for processing data and executing instructions in a computer system
    • Performs arithmetic, logical, and input/output operations

    RAM (Random Access Memory)

    • Provides temporary storage for data that the CPU needs to access quickly
    • Allows for faster data retrieval compared to other storage devices like hard drives

    GPU (Graphics Processing Unit)

    • Primarily responsible for rendering and processing graphics
    • Optimized for parallel processing and handles complex calculations required for graphic-intensive applications

    Motherboard

    • Vital component that connects and facilitates communication between various hardware components
    • Houses the CPU, RAM, GPU, and other essential components
    • Provides expansion slots, connectors, and interfaces for connecting peripherals

    Data Types

    Integers (int)

    • Whole numbers without decimal points
    • Used for counting, indexing, and performing arithmetic operations

    Float (Floating-point numbers)

    • Represent real numbers with decimal points
    • Used when precise decimal values or calculations involving fractions are required

    Assigning Values in Python

    • The assignment operator (=) is used to assign values to variables
    • The variable on the left side of the assignment operator receives the value on the right side

    Comparing Values in Python

    • The equality operator (==) is used to compare values in Python
    • Returns a Boolean value (True/False) based on the comparison result

    Importance of Proper Syntax

    • Essential in programming to ensure the code is written correctly and can be understood by the computer
    • Incorrect syntax can lead to syntax errors, preventing the code from being executed successfully

    HTML and its Role in Web Development

    Defining HTML

    • Stands for Hypertext Markup Language
    • Standard markup language used for creating web pages and applications
    • Uses tags to structure content and define elements on a web page

    Role of HTML in Web Development

    • Backbone of web development, responsible for creating the structure and layout of web pages
    • Defines various elements such as headings, paragraphs, lists, images, links, tables, and forms
    • Provides the foundation for adding text, multimedia, and interactivity to web pages

    Variables in Python

    • Used to store and manipulate data
    • Act as containers that hold values of different types such as numbers, strings, or Boolean values
    • Allow for temporary or permanent data storage for later use in programs
