ASCII Code and Binary
Summary
TLDRThis educational video script teaches viewers how to convert words into their ASCII binary equivalents and vice versa. It starts by explaining the ASCII system and provides a partial ASCII table. The script demonstrates converting the word 'blue' into binary by assigning decimal values to each letter and then converting those to 7-bit binary codes. It also shows how to reverse the process, converting binary codes back into the word 'lemon' using the ASCII table. The tutorial is designed to help users understand the basics of ASCII encoding and binary representation.
Takeaways
- π€ ASCII stands for American Standard Code for Information Interchange.
- π The ASCII table provided is partial, focusing on certain characters.
- π‘ The task is to convert the word 'blue' into its binary representation using ASCII values.
- π The ASCII code system is a seven-bit binary system.
- π’ Each letter's ASCII value is converted to binary by breaking it down into powers of two (64, 32, 16, 8, 4, 2, 1).
- π ±οΈ The capital letter 'B' has a decimal value of 66, which translates to the binary '0100001'.
- π °οΈ The lowercase 'L' has a decimal value of 108, which translates to the binary '1101100'.
- π The lowercase 'U' has a decimal value of 117, which translates to the binary '01110101'.
- π ΎοΈ The lowercase 'E' has a decimal value of 101, which translates to the binary '01100101'.
- π The process can be reversed to convert binary codes back into words using the ASCII table.
- π An example binary message translates to the word 'lemon' when converted back to ASCII.
Q & A

How do you convert a binary code back to its corresponding ASCII character?
-You convert a binary code back to its corresponding ASCII character by summing the values of the bits set to 1 and then finding the character with that decimal value in the ASCII table.
What is the word represented by the binary code '1100101' in ASCII?
-The binary code '1100101' corresponds to the letter 'm' in ASCII.
What is the process of converting a word into binary using the ASCII table?
-The process of converting a word into binary using the ASCII table involves finding the decimal values of each letter, then converting those decimal values into their respective seven-bit binary codes.
