The Secret Language of Computers

Exploring Binary Code and Data Representation.

The presentation agenda outlines four key sections on binary computing. It covers binary fundamentals (bits, bytes, data representation), encoding and execution (ASCII, compilers), tech applications (networking, real-world examples), and evolution with takeaways.

Presentation Agenda

1. 1. Binary Fundamentals

Intro to computer language, what is binary, bits & bytes, data representation.

2. 2. Encoding & Execution

ASCII & encoding systems, machine code, compilers & interpreters.

3. 3. Applications in Tech

Computers use binary digital signals—1 for ON and 0 for OFF—with no natural language, as everything translates to binary code. This binary foundation powers all software, data, and hardware communication, revealing the secret language of modern computing.

Introduction to Computer Language

• • Computers use digital signals: ON (1) / OFF (0)
• • No natural language; everything translates to binary
• • Binary foundations all software, data, and hardware communication
• • Unlocks the secret language powering modern computing

Binary code is a base-2 numeral system that uses only 0s and 1s. It represents all data computers process and store, powering text, images, audio, and video content.

What is Binary Code?

A bit is the smallest unit of data, either 0 or 1, while a byte combines 8 bits, like 10110110. Bytes scale to kilobytes (1024 bytes), terabytes, and petabytes, forming the foundation of digital storage and enabling text and number representation.

Bits and Bytes

• Bit: smallest unit of data, either 0 or 1
• Byte: 8 bits combined, e.g., 10110110
• Kilobyte: 1024 bytes, scaling to TB and PB
• Bits form foundation of all digital storage
• Bytes enable representation of text and numbers

The slide explains how numeric data is stored in binary, like decimal 5 as 101, aligning with transistors' on (1) and off (0) states for fast switching. It also covers multimedia data, such as RGB colors (e.g., red as 255,0,0 in binary), images as pixel grids, and text/audio encoded as 0s and 1s patterns.

The slide "ASCII and Encoding Systems" features a table mapping characters 'A', 'a', '!', and '0' to their ASCII decimal values (65, 97, 33, 48) and 8-bit binary equivalents (01000001, 01100001, 00100001, 00110000). It illustrates how text characters are represented in binary for computing.

This slide depicts the workflow from high-level code to CPU execution. It progresses through human-readable languages (e.g., Python/C++), assembly instructions, binary machine code, and the fetch-decode-execute cycle, with examples at each stage.

Machine Code and Instructions

{ "headers": [ "Stage", "Description", "Example" ], "rows": [ [ "High-Level Code", "Human-readable code in languages like Python or C++", "if (x > 0) { print('Hello'); }" ], [ "Assembly Language", "Low-level symbolic instructions for specific CPU", "CMP AX, 0 JG label" ], [ "Machine Code", "Binary opcodes directly executed by CPU", "1010 0001 0010 0011 (ADD R1, R2)" ], [ "CPU Execution", "Fetch-Decode-Execute cycle processes instructions", "Fetch: 1010... → Decode: ADD → Execute: R1 += R2" ] ] }

Source: Flow: High-level code → Assembly → Machine code (binary ops like ADD 1010). CPU executes: Fetch-Decode-Execute cycle.

Compilers translate entire source code to machine code (e.g., C++ to .exe), while interpreters execute code line-by-line at runtime (e.g., Python). They bridge human-readable languages to binary instructions, enabling efficient programming without direct binary coding.

Translation: Compilers & Interpreters

• Compilers translate entire source code to machine code (e.g., C++ → .exe)
• Interpreters execute code line-by-line at runtime (e.g., Python)
• Bridge human-readable languages to binary machine instructions
• Enable efficient programming without direct binary coding
