Understanding Character Sets in Computing

The video tutorial explains how computers represent characters using binary codes and explores character sets like ASCII and Unicode. It discusses the need for standardized character encoding to ensure consistency across different systems. ASCII, a 7-bit character set, was an early standard, later extended to 8 bits to include more characters. Unicode, a more comprehensive character set, supports international and multilingual characters, including emojis. The video highlights the importance of character encoding standards in computer systems.

Why do computers need to represent characters in binary?

• To save storage space

• To make data processing faster

• To ensure compatibility across devices

• Because computers can only process binary data

What is a character set in computing?

• A type of data storage format

• A set of rules for programming languages

• A defined list of characters recognized by computer hardware and software

• A collection of fonts used by a computer

What was the primary limitation of the original ASCII character set?

• It was too complex to implement

• It was not compatible with modern computers

• It could only represent English letters

• It was limited to 128 characters

How many bits are used in the extended ASCII character set?

• 7 bits

• 8 bits

• 16 bits

• 24 bits

What is the main advantage of Unicode over ASCII?

• It is easier to understand

• It is faster to process

• It supports a larger number of characters

• It is more secure

What is UTF-8?

• A type of computer hardware

• A programming language

• A data compression format

• A variant of Unicode used for web pages

How many different characters can be represented in a 24-bit Unicode character set?

• 1 billion characters

• 65,536 characters

• 16 million characters

• 256 characters

Why is hexadecimal used in conjunction with 24-bit Unicode?

• To make it more secure

• To reduce storage requirements

• To simplify the representation of binary data

• To increase processing speed

What was the original bit size of Unicode?

• 32 bits

• 24 bits

• 16 bits

• 8 bits

Which of the following is NOT a reason for the development of Unicode?

• To standardize character representation across platforms

• To support international and multilingual character sets

• To replace all existing programming languages

• To include modern characters like emojis
