Digital Information and Binary Representation Quiz

What is digital information in the context of modern technology?

• Information stored using analog signals

• Information represented using continuous number systems

• Information encoded using discrete symbols

• Information transmitted through electromagnetic waves

How does binary representation relate to computer systems?

• It enables computers to process information using analog principles

• It allows computers to store information in continuous ranges

• It simplifies data processing by using a set of 16 symbols: 0 – 9 and A – F

• It forms the basis for digital encoding and manipulation in computers

Place the following binary numbers in order from smallest to largest: I. 1001 0011 II. 0011 1100 III. 1010 0010

• II, III, I

• III, II, I

• I, III, II

• II, I, III

What is an overflow error in numeric representations?

• It occurs when a program has too many syntax errors.

• It happens when a program's runtime exceeds a certain limit.

• It's a logic error that causes incorrect results due to a wrong algorithm.

• It occurs when a calculation results in a value that's too large to be stored within a given data type.

Why do we use hexadecimal representations for digital data in computing?

• Hexadecimal is the most efficient representation for all types of data.

• Hexadecimal is the native format used by modern computer hardware.

• Hexadecimal provides a compact way to represent large binary values.

• Hexadecimal ensures compatibility with non-digital devices.

• III, I, II

• II, I, III

• II, III, I

• I, III, II

Which of the following statements is TRUE?

• Logic errors are caused by incorrect program structure.

• Run-time errors result in code that runs too slowly.

• Syntax errors lead to compiler errors.

• All of the above are true.
