Decoding Binary Representation of Data

The video explores how computers store and represent numerical data using binary systems. It explains the conversion between decimal and binary, binary arithmetic, and the significance of bits and bytes. The video also covers 32-bit and 64-bit systems, floating point numbers, and text representation through ASCII and Unicode. It highlights the evolution of encoding systems to accommodate global languages and the importance of interoperability in computing.

What are the two binary values used in computing?

• On and Off

• 0 and 1

• 1 and 2

• True and False

How is the number 5 represented in binary?

• 111

• 110

• 101

• 100

What is the highest value an 8-bit number can represent?

• 100

• 256

• 1024

• 255

How many bits are in a byte?

• 16

• 64

• 8

• 32

What does a kilobyte traditionally represent?

• Both 1000 bytes and 1024 bytes

• 1024 bytes

• 1000 bytes

• 8000 bits

What is the largest number a 32-bit system can represent?

• Just under 4.3 billion

• Over 9 billion

• Approximately 2 billion

• Exactly 1 million

What is the purpose of the first bit in a 32-bit floating point number?

• To increase precision

• To indicate the sign of the number

• To store the significand

• To represent the exponent

What does ASCII stand for?

• Advanced System for Code Information Interchange

• American Standard Code for Information Interchange

• American System for Computerized Information Exchange

• Automated Standard Code for International Interchange

What was a major limitation of ASCII?

• It was too complex

• It could not represent numbers

• It could only represent English characters

• It used too much memory

What does Unicode aim to provide?

• A compact form of text storage

• An improved version of ASCII for English

• A new way to represent binary data

• A universal encoding scheme for all languages
