Understanding ASCII and Unicode Standards

What does ASCII stand for?

• American Standard Code for Information Interchange

• American Standard Code for International Interchange

• American System Code for Information Interchange

• American System Code for International Interchange

How many bits are used in the standard ASCII encoding?

• 7 bits

• 8 bits

• 16 bits

• 32 bits

Which of the following is a key difference between ASCII and Unicode?

• ASCII uses 16 bits, while Unicode uses 7 bits

• ASCII can represent more characters than Unicode

• Unicode can represent characters from multiple languages, while ASCII cannot

• ASCII is newer than Unicode

What is the primary purpose of Unicode?

• To provide a unique number for every character, regardless of platform, program, or language

• To replace binary numbers with characters

• To compress data for efficient storage

• To encrypt data for security

In which year was the first version of ASCII published?

• 1963

• 1971

• 1990

What is the binary representation of the ASCII character 'A'?

• 01000001

• 01100001

• 00100001

• 11000001

Which Unicode standard is most commonly used in modern computing?

• 256

• 65,536

• 1,114,112

• 2,147,483,648

Which of the following is an application of Unicode?

• Data compression

• Internationalisation of software
