Binary and Search Algorithms Quiz

What does a binary system use to represent data?

• Numbers from 0 to 9

• Only the number 1

• Digits 0 and 1

• Letters A to Z

Convert the decimal number 13 to binary:

• 1101

• 1010

• 1001

• 1110

What is the binary equivalent of the decimal number 9?

• 1001

• 1010

• 1100

• 1111

Why is binary important in computer science?

• It is easier for humans to understand.

• Computers process data as on/off signals, represented by 0s and 1s.

• It replaces the need for algorithms.

• It is the universal language for humans.

Which of the following is NOT true about binary numbers?

• They are used for machine-level operations.

• They are represented by 0 and 1.

• They are complex for computers to process.

• Binary simplifies circuit design.

What is a linear search?

• Searching in a sorted list by dividing it in half.

• Searching sequentially through each element of a list.

• Searching randomly in a list.

• Searching by skipping elements.

Which of the following describes binary search?

• It works only on sorted datasets.

• It searches each element one by one.

• It works without sorting.

• It finds all elements simultaneously.

What is the primary difference between linear and binary search?

• Linear search skips elements, binary search checks all.

• Binary search requires sorting, linear does not.

• Linear search is faster for large datasets.

• Binary search is slower for small datasets.

In which scenario is binary search most efficient?

• Small unsorted datasets

• Large sorted datasets

• Randomized datasets

• Real-time search

What happens in binary search if the dataset is not sorted?

• It still works perfectly.

• It performs slower.

• It fails to give accurate results.

• It becomes a linear search.
