Summary of "COMPUTER SCIENCE explained in 17 Minutes"
Computers are made up of a Central Processing Unit (CPU) with microscopic switches called transistors that can be on or off, representing 1s and 0s in binary.
Binary is a system for storing information, while hexadecimal is a more readable format.
Logic gates are used to perform calculations based on Boolean algebra.
Character encoding like ASCII assigns binary numbers to characters for human readability.
Operating systems manage how computer hardware and applications work together.
Instructions are given to the computer in machine code, and the CPU executes them in machine cycles.
Programming languages use variables, data types, and functions to write code that is converted into machine code.
Data structures like arrays, linked lists, queues, stacks, hash maps, and graphs are used to organize and work with data.
Algorithms are sets of instructions that solve problems step by step, and recursion can be used to break down problems into smaller parts.
Time and space complexity of algorithms are measured using Big O notation.
Programming paradigms like declarative, imperative, object-oriented, and machine learning are used to solve problems with code.
The internet and the web are networks of computers connected by wires, allowing data transfer using protocols like TCP and HTTP.
Databases store data in tables, and SQL is used to query and manipulate data.
Learning these concepts can be done effectively through interactive lessons on platforms like Brilliant.
Brilliant offers interactive lessons for math, data science, programming, and AI, making learning fun and effective.
