AS IT MCQ Quiz 2

Which of the following best describes a compiler?

• It translates high-level language into machine language line by line.

• It translates high-level language into machine language all at once.

• It interprets the program line by line at runtime.

• It executes instructions directly without translation.

What is the primary difference between a compiler and an interpreter?

• A compiler translates the code line-by-line, while an interpreter translates all the code at once.

• A compiler translates the entire program before execution, while an interpreter translates code during execution.

• A compiler and an interpreter work the same way.

• An interpreter translates machine code into high-level language, while a compiler does not.

Which of the following is true about an interpreter?

• It provides faster execution because it translates the whole code before execution.

• It stops execution when an error is encountered and does not continue.

• It stores the translated code for future use.

• It converts high-level code into machine code once and for all.

An assembler is used to:

• Convert high-level code into intermediate code.

• Convert machine code into high-level programming language.

• Convert assembly language into machine code.

• Execute assembly code directly.

Which of the following statements about the execution process of a compiler and an interpreter is true?

• A compiler translates the entire source code into object code in one go, while an interpreter translates the source code line-by-line.

• An interpreter translates the whole program at once, while a compiler translates line-by-line.

• Both compiler and interpreter execute code at the same time.

• A compiler does not generate any machine code.

Which of the following is a disadvantage of using an interpreter?

• It performs faster execution of code.

• It generates an output file that can be executed later.

• It requires re-translation each time the program runs.

• It can handle both high-level and low-level languages.

The primary advantage of using a compiler over an interpreter is:

• Compilers provide immediate feedback after translating each line.

• Compilers execute code faster because the translation happens before execution.

• Compilers are easier to implement.

• Compilers do not need to generate any output file.

Mainframe computers are designed to:

• Provide high-performance computing for a large number of users.

• Run operating systems designed for individual users.

• Be affordable for small businesses and startups.

• Be used primarily for mobile applications.

Mainframe computers are known for their:

• High speed in individual computing tasks.

• Scalability to handle large amounts of data and users.

• Use of simple, inexpensive processors.

• Portability and mobility.

What does RAS stand for in the context of mainframe computers?

• Reliability, Accessibility, Security

• Reliability, Availability, Serviceability

• Recovery, Availability, Serviceability

• Reliability, Application, Serviceability
