Exploring Computer Science Concepts

What is the primary function of an operating system?

• To provide internet connectivity

• To protect against malware attacks

• To run applications without user input

• The primary function of an operating system is to manage hardware and software resources.

Define the term 'algorithm' in computer science.

• An algorithm is a programming language used for coding.

• An algorithm is a type of computer hardware.

• An algorithm is a random collection of data.

• An algorithm is a finite sequence of well-defined instructions for solving a problem or performing a task.

What is the difference between RAM and ROM?

• RAM is used for permanent storage; ROM is used for temporary storage.

• RAM is non-volatile and used for temporary storage; ROM is volatile and used for permanent storage.

• RAM is volatile and used for temporary storage; ROM is non-volatile and used for permanent storage.

• RAM and ROM are both volatile and used for the same purpose.

Explain the concept of object-oriented programming.

• Object-oriented programming focuses solely on functions and not on data.

• Object-oriented programming is a method for writing procedural code.

• Object-oriented programming eliminates the need for any form of data encapsulation.

• Object-oriented programming is a paradigm that uses 'objects' to represent data and methods, promoting code reusability and modular design.

What does HTML stand for?

• HighText Markup Language

• HyperText Markup List

• HyperText Multi Language

• HyperText Markup Language

What is the purpose of a database management system?

• To create random data without structure.

• To eliminate the need for data security.

• The purpose of a database management system is to manage and organize data effectively.

• To store data in a physical format only.

Describe the function of a compiler.

• The function of a compiler is to convert high-level programming code into machine code.

• The function of a compiler is to execute programs directly on the hardware.

• A compiler translates machine code into high-level programming code.

• A compiler is used to debug code and find errors in programming.

What is the significance of the TCP/IP model?

• The TCP/IP model is a hardware specification for routers.

• The TCP/IP model is essential for enabling reliable communication over the internet and ensuring interoperability between diverse networked systems.

• The TCP/IP model is primarily used for file storage.

• The TCP/IP model is only relevant for local networks.

What is the difference between a stack and a queue?

• A stack uses FIFO, while a queue uses LIFO.

• A stack can only hold integers, while a queue can hold any data type.

• Both stack and queue use LIFO.

• A stack uses LIFO, while a queue uses FIFO.

Define 'big O notation' and its importance in algorithms.

• Big O notation is a programming language used for coding.

• Big O notation is a method for debugging algorithms.

• Big O notation is a way to express the efficiency of algorithms, indicating their time or space complexity in relation to input size.

• Big O notation measures the popularity of algorithms.
