What is the difference between a compiler and an interpreter?

• A compiler and an interpreter perform the same function.

• The main difference is that a compiler translates the entire program into machine code before execution, while an interpreter translates and executes the code line by line.

• A compiler translates code line by line, while an interpreter translates the entire program at once.

• A compiler is used for high-level languages, while an interpreter is used for low-level languages.

What is the purpose of version control systems like Git?

• To track changes in code, collaborate with others, revert to previous versions, and manage different versions of a project.

• To go skydiving

• To bake cookies

• To learn a new language

What is the concept of 'Big O notation' in algorithm analysis?

• Big O notation is only applicable to sorting algorithms.

• Big O notation is used to analyze the efficiency of algorithms by describing how the runtime or space requirements decrease as the input size increases.

• Big O notation is used to analyze the efficiency of algorithms by describing how the runtime or space requirements remain constant regardless of input size.

• Big O notation is used to analyze the efficiency of algorithms by describing how the runtime or space requirements grow as the input size increases.

What is the difference between front-end and back-end development?

• Front-end development is concerned with data management, while back-end development focuses on the user experience.

• Front-end development deals with server-side operations, while back-end development focuses on the user interface.

• Front-end development focuses on hardware, while back-end development focuses on software.

• Front-end development focuses on the user interface and experience, while back-end development deals with the server-side and data management.

What is the importance of cybersecurity in the digital age?

• Cybersecurity is only important for large companies

• Cybersecurity has no impact on data protection

• Cybersecurity is not necessary in the digital age
