    Voice Recognition (Audio to Binary)

                  When you speak, your voice creates analog sound waves. A microphone captures these waves, and an
                  Analog-to-Digital Converter (ADC) samples the wave's amplitude thousands of times per second.
                      Each sample is assigned a binary value.

                       AI models (like those in virtual assistants) analyse these binary patterns to identify phonemes, the
                     smallest units of sound, to "understand" what was said.

                  Text Recognition (Symbols to Binary)

                  Text is handled through standardised encoding systems like UTF-8 or ASCII (American Standard Code
                  for Information Interchange).

                       Every character (A, b, !, ?) is mapped to a specific number. For instance, the letter "A" is represented
                     as 65 in decimal, which becomes 01000001 in binary.
                       Modern AI (Large Language Models) takes this a step further by converting these binary-coded words
                     into embeddings—long lists of numbers that represent the word's meaning and context.

                              Quick Quiz

                    1.  What is the result of converting the decimal number 20 to binary?

                               a. 10110                                      b. 10100
                    2.  What is the decimal equivalent of the binary number 1101?

                               a. 11                                         b. 13

                                Recap

                                A number system is a systematic way of representing numbers in terms of quantities.
                                The decimal number system consists of ten digits from 0 to 9.

                                The binary number system consists of two digits, 0s and 1s.
                               The octal number system is used as a shorthand representation of long binary numbers.

                                The hexadecimal number system consists of 16 digits from 0 to 9 and letters from A to F
                               In Artificial Intelligence (AI), binary is a fundamental part of how information is processed.
                                When AI processes an image, it doesn't see it the way humans do. Instead, it converts the image
                              into a grid of numbers.
                                When you speak, your voice creates analog sound waves. A microphone captures these waves,
                              and an Analog-to-Digital Converter (ADC) samples the wave's amplitude thousands of times per
                              second.
                                Text is handled through standardised encoding systems like UTF-8 or ASCII (American Standard
                              Code for Information Interchange).
