Question 1

In which text compression technique is it invalid for a bit string that represents a character to be the prefix of any other string used to represent a character?

Accepted Answer

Huffman encoding is a prefix-free encoding technique, meaning no bit string representing a character is a prefix of any other bit string used to represent another character.

Question 2

Which technique for representing numeric data uses the mantissa to hold the significant digits of a value?

Accepted Answer

Floating point representation uses the mantissa to hold the significant digits of a value, allowing for a wide range of values with varying precision.

Question 3

Information is data that has been organized and/or processed in a useful way.

Accepted Answer

Information is data that has been structured or interpreted to provide meaning or value, making it useful for decision-making or understanding.

Question 4

Electronic signals are easier to manage if they transfer only binary data.

Accepted Answer

Binary data simplifies electronic signal management because it reduces complexity, allowing for easier processing, error detection, and correction.

Question 5

Every additional bit used doubles the number of things that can be represented by a binary string.

Accepted Answer

Each additional bit in a binary string doubles the number of possible combinations, as each bit has two possible states (0 or 1), leading to an exponential increase in representable values.

Question 6

A character set is a list of characters and their numeric codes.

Accepted Answer

A character set defines a mapping between characters and their corresponding numeric codes, allowing computers to store and manipulate text.

Question 7

The ASCII character set is an international set that represents most of the world's languages.

Accepted Answer

The ASCII character set is limited to 128 characters and primarily represents English characters and control codes, not most of the world's languages.

Question 8

Run-length encoding replaces common words with shorter symbols.

Accepted Answer

Run-length encoding is a compression technique that replaces consecutive repeated characters or data elements with a single character or element followed by the count of repetitions, not common words with symbols.
