    • What is character encoding used for?
      Representing text numerically
    • What type of characters does ASCII primarily cover?
      English alphanumeric
    • The letter 'A' is encoded as 65 in ASCII.
    • Why is character encoding essential for computers?
      Standardized text processing
    • The ASCII encoding standard uses 7 bits to represent each character.
    • UTF-8 is backward compatible with ASCII.
      True
    • Why is UTF-8 often preferred over Unicode?
      Backward compatibility
    • The letter 'A' is encoded as 65 in ASCII and U+0041 in Unicode.
    • Match the encoding standard with its key characteristics:
      ASCII ↔️ Uses 7 bits, limited language support
      Unicode ↔️ Extensive characters from most languages
    • How many bits does Unicode use to represent characters?
      16
    • Order the following encoding standards by their range of supported characters:
      1️⃣ ASCII
      2️⃣ Unicode
    • ASCII uses 7 bits to encode characters.
    • UTF-8 is backward compatible with ASCII.
    • UTF-8 uses a variable-length encoding for characters.
      True
    • The ASCII encoding standard uses a range of 0-127
    • Unicode supports over one million characters and symbols.

      True
    • Match the encoding standard with its range:
      ASCII ↔️ 0-127
      Unicode ↔️ 0-1,114,111
    • Unicode ensures that the same character appears correctly across different platforms.

      True
    • What is one key benefit of Unicode compared to ASCII?
      Comprehensive language support
    • Match the encoding standard with its key characteristic:
      ASCII ↔️ Basic English text
      Unicode ↔️ Comprehensive character coverage
      UTF-8 ↔️ Variable-length encoding
    • What is the maximum number of characters supported by Unicode?
      1,114,111
    • Character encoding is a method used to represent text characters and symbols as numeric codes for computers to understand them.

      True
    • In ASCII, the letter 'A' is encoded as the number 65
    • The encoding of 'A' is consistent across ASCII and Unicode.
      True
    • What is one major benefit of Unicode?
      Comprehensive language support
    • Match the encoding standard with its example:
      ASCII ↔️ "A" is 65
      UTF-8 ↔️ "€" is 0xE2 0x82 0xAC
    • Which encoding standard is primarily used for English text?
      ASCII
    • UTF-8 balances coverage and efficiency, and is compatible with ASCII.
