Text and Image representation

Why do we need to encode all data in binary.

• Because binary is very small

• Because computers only understand binary

• Because binary is very fast

• Because binary is space efficient

A defined list of characters & symbols with associated binary codes are called..

• Storage data

• Numerical configuration

• Character sets

• Number sets

2 examples of character sets are

• CSCII

• ASCI

• ASCII

• UNICODE

How can character encoding issues arise?

• When software tries to decode text using a different character set

• When software tries to decode text using the right character set

• When character sets are too fast

• When character sets are too big

What happens when software tries to encode with the wrong character set?

• Hardware conflict

• System update crash

• Slow system

• Encoding issues can arise

What is the full meaning of ASCII ?

• Advanced Standard Code for Information Interchange

• American Standard Code for Information Interchange

• American Standard Code for Internet Interchange

• Advance Set Code for Information Interchange

ASCII is a 7 bit character set

• True

• False

ASCII allows for a maximum of how many different characters?

• 128

• 256

• 64

• 32

One main problem with ASCII is ...

• Has only big letters and alphabets for all languages

• Has too many letters and alphabets for all languages

• Has no letters and alphabets for all languages

• No problem

Which character set allows for the encoding of every character and symbol for every language in the world

• SCII

• ASCII

• UNICODE

• UTFCODE
