Exploring characters

Cards (28)

  • Characters represent letters, numbers, symbols, and control characters
  • Match the encoding scheme with its definition and character range:
    ASCII ↔️ American Standard Code for Information Interchange ||| 128 characters (0-127)
    Unicode ↔️ Universal character encoding standard ||| Over 100,000 characters (0-1,114,111)
  • Unicode supports characters from most world languages.

    True
  • Unicode is a comprehensive encoding that supports characters from most of the world's writing systems
  • What are characters in data storage?
    Basic units of data storage
  • What does ASCII stand for?
    American Standard Code for Information Interchange
  • Unicode supports over 100,000 characters.

    True
  • ASCII uses 7 bits to represent 128 characters.
  • ASCII has the advantage of simplicity and small storage size.
    True
  • ASCII uses 7 bits to represent 128 characters.
  • Unicode supports a global range of languages and symbols.

    True
  • Unicode's larger storage size is a disadvantage compared to ASCII.
  • Unicode improves global communication and interoperability.
    True
  • What are characters in data storage?
    Basic units of data
  • Characters are stored using character encoding schemes.

    True
  • ASCII only supports English characters and basic symbols
  • How many characters does ASCII support?
    128
  • Arrange the character encoding schemes from smallest to largest character range:
    1️⃣ ASCII (128 characters)
    2️⃣ Unicode (over 100,000 characters)
  • Unicode has a smaller storage size compared to ASCII.
    False
  • Characters in data storage represent letters, numbers, symbols, and control characters
  • ASCII and Unicode are the two main character encoding schemes.

    True
  • ASCII supports a character range of 128
  • Which encoding scheme supports characters from most of the world's writing systems?
    Unicode
  • What are examples of Unicode encoding formats?
    UTF-8, UTF-16, UTF-32
  • What is a disadvantage of Unicode?
    Larger storage size
  • How many bits does Unicode use per character in UTF-8 encoding?
    8-32 bits
  • Match the encoding scheme with its key characteristic:
    ASCII ↔️ Simplicity and small size
    Unicode ↔️ Supports multiple languages
  • Why does Unicode require more storage space than ASCII?
    Supports more characters
