Computer Science Challenge

What is the purpose of algorithms in computer science?

• To confuse computer users

• To solve problems and perform specific tasks.

• To create more problems

• To slow down computer operations

Name three high-level programming languages commonly used in software development.

• Java, Python, C#

• HTML, CSS, JavaScript

• Assembly, Fortran, COBOL

• Ruby, Swift, Perl

Explain the concept of a linked list and its advantages over an array.

• A linked list is a data structure that consists of nodes where each node contains a data field and a reference(link) to the next node in the sequence. The main advantage of a linked list over an array is that it allows for efficient insertion and deletion of elements, as it does not require shifting of elements.

• The main advantage of a linked list over an array is that it takes up less memory

• A linked list is a type of array that allows for random access of elements

• A linked list is a type of spreadsheet used for organizing data

What are the main components of a computer's central processing unit (CPU)?

• Printer, scanner, and speakers

• Hard drive, RAM, and motherboard

• Arithmetic logic unit (ALU), control unit, and registers

• Keyboard, mouse, and monitor

What is the importance of cybersecurity in the digital age?

• Cybersecurity is not important in the digital age

• Cyber attacks are not a real threat in the digital age

• It is only important to protect physical documents, not digital information

• It is important to protect sensitive information, prevent cyber attacks, and ensure safety and privacy.

Define artificial intelligence and provide an example of its application.

• AI is used in applications like virtual assistants (e.g. Siri, Alexa), recommendation systems (e.g. Netflix, Amazon), and autonomous vehicles.

• AI is used in applications like typewriters and fax machines.

• AI is only used in science fiction movies and has no real-world applications.

• AI is used in applications like microwave ovens and toasters.

What is the time complexity of a binary search algorithm?

• O(n^2)

• O(log n)

• O(n)

• O(1)

Compare and contrast symmetric and asymmetric encryption algorithms.

• Symmetric encryption uses a public key for encryption and a private key for decryption.

• Symmetric encryption is more secure than asymmetric encryption.

• Asymmetric encryption uses the same key for both encryption and decryption.

• Symmetric encryption uses the same key for both encryption and decryption, while asymmetric encryption uses a public key for encryption and a private key for decryption.

Explain the difference between RAM and ROM in computer hardware.

• RAM is volatile and temporary, while ROM is non-volatile and permanent.

• RAM and ROM are both non-volatile and permanent.

• RAM and ROM are both volatile and temporary.

• RAM is non-volatile and permanent, while ROM is volatile and temporary.

How does a neural network function in the context of machine learning?

• By using interconnected nodes to cook food

• By using interconnected nodes to play video games

• By using a single node to process and analyze data

• By using interconnected nodes to process and analyze data
