Understanding Computer Character Sets

What is the primary reason computers use binary code?

• To increase processing speed

• To enhance graphics rendering

• To reduce manufacturing costs

• To simplify the design of circuits

How many characters could the original ASCII character set encode?

• 64 characters

• 512 characters

• 256 characters

• 128 characters

What was a major limitation of ASCII that led to the development of Extended ASCII?

• It was not compatible with most computers

• It required too much memory

• It could not represent non-English characters

• It was too slow to process

Which of the following characters was not included in the original ASCII set?

• Exclamation mark (!)

• Ampersand (&)

• Pound sign (£)

• Dollar sign ($)

What additional capability does Extended ASCII have over ASCII?

• Support for 128 characters

• Support for 256 characters

• Support for 1024 characters

• Support for 512 characters

Why was Unicode developed?

• To reduce the memory usage

• To support a limited number of characters

• To include characters from multiple languages

• To speed up the processing time

How many bytes can each Unicode character use?

• Between 1 and 4 bytes

• Between 1 and 2 bytes

• Exactly 2 bytes

• Exactly 1 byte

What is a unique feature of Unicode in terms of character support?

• Supports exactly 256 characters

• Supports billions of characters

• Supports only English characters

• Supports only ASCII characters

Which of the following is a consequence of using Unicode?

• Reduces the variety of characters

• Does not affect storage space

• Increases storage space per character

• Decreases storage space per character

What does the development of character sets like Unicode allow in modern computing?

• Representation of diverse languages and symbols

• Exclusive use of English language

• Reduction in the use of emojis

• Decrease in global communication
