Grade 11 System Software Quiz

What are the properties used to describe different operating systems?

• Cost, size, hardware, platform

• Speed, memory, software, compatibility

• Color, shape, weight, design

• Price, dimensions, brand, color

What is the difference between programming language compilers and interpreters?

• Compilers translate high level language into machine code, while interpreters translate line by line and execute simultaneously

• Compilers execute code directly, while interpreters translate code into machine code

• Compilers translate machine code into high level language, while interpreters execute code directly

• Compilers translate high level language into machine code, while interpreters translate line by line and execute sequentially

What is the purpose of virtual machines?

• To allocate virtual memory for running programs

• To create virtual devices for accessing hardware

• To host multiple operating systems on a single machine

• To execute machine code directly without translation

What is virtualisation?

• The process of creating virtual devices

• The use of secondary storage as virtual main memory

• The ability of the OS to switch between computing tasks

• The use of two or more processors within a single computer system

What is the content of a program file (executable file)?

• Binary machine code

• High level code

• RAM data

• Virtual memory

Which of the following is a high level language?

• Python

• Machine code

• Binary

• Assembly language

What does a compiler do?

• Translates high level language into machine code

• Executes code directly

• Translates machine code into high level language

• Allocates virtual memory for running programs

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

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

• A compiler executes code directly, while an interpreter translates code into machine code

• A compiler is faster when developing a program, while an interpreter is faster during execution

• A compiler produces an executable file, while an interpreter requires the interpreter to run the program

What is multitasking?

• The ability of the OS to switch between computing tasks

• The use of two or more processors within a single computer system

• Operations within a single application divided into threads

• The use of secondary storage as virtual main memory

What is virtual memory?

• Part of the hard drive used as an extension to RAM

• The use of secondary storage as virtual main memory

• The ability of the OS to switch between computing tasks

• The use of two or more processors within a single computer system
