Year 11 Software Engineering Yearly Revision Test 3

Which of the following is a high-level programming language?

• Assembly

• Python

• Machine code

• Binary

• Opcode

Answer explanation

Python is a high-level programming language known for its readability and ease of use. In contrast, Assembly, machine code, binary, and opcode are low-level languages that are closer to hardware and less abstract.

In software development, what does IDE stand for?

• Integrated Development Environment

• Internal Design Evaluation

• Instructional Debugging Engine

• Independent Data Entry

• Information Design Editor

Answer explanation

In software development, IDE stands for Integrated Development Environment. It is a software application that provides comprehensive facilities to programmers for software development, including code editing, debugging, and testing.

Which of these is an example of a logic error?

• Division by zero

• Infinite loop caused by wrong condition

• Missing semicolon

• Misspelling a keyword

• Incorrect variable type

Answer explanation

An infinite loop caused by a wrong condition is a logic error because the code runs indefinitely due to incorrect logic. In contrast, division by zero, missing semicolon, misspelling a keyword, and incorrect variable type are syntax or runtime errors.

A compiler translates:

• High-level code to low-level code

• Binary to Assembly

• Pseudocode to flowchart

• HTML to CSS

• Algorithms to pseudocode

Answer explanation

A compiler translates high-level code (like C++ or Java) into low-level code (like machine code or assembly) so that the computer can execute it. This is the primary function of a compiler, making 'High-level code to low-level code' the correct choice.

Which of the following is not a programming paradigm?

• Object-oriented

• Functional

• Procedural

• Declarative

• Binary-coded decimal

Answer explanation

Binary-coded decimal (BCD) is a method of encoding decimal numbers, not a programming paradigm. The other options—Object-oriented, Functional, Procedural, and Declarative—are all recognized programming paradigms.

The purpose of version control software is to:

• Store files in binary

• Keep track of program versions and changes

• Increase CPU performance

• Compile faster

• Debug automatically

Answer explanation

The correct choice is 'Keep track of program versions and changes' because version control software is designed to manage and track changes in code, allowing multiple versions to be maintained and collaborated on effectively.

Which of the following is a runtime error?

• Syntax error

• File not found error

• Missing semicolon

• Misuse of keyword

• Indentation error

Answer explanation

A runtime error occurs during program execution. The 'File not found error' is a runtime error because it happens when the program tries to access a file that doesn't exist. The other options are syntax errors that occur before execution.

In object-oriented programming, an instance of a class is called a:

• Method

• Function

• Object

• Attribute

• Variable

Answer explanation

In object-oriented programming, an instance of a class is referred to as an 'Object'. This is the fundamental concept where an object represents a specific realization of a class, encapsulating data and behavior.

Encapsulation in OOP is used to:

• Hide implementation details

• Increase program speed

• Prevent compilation errors

• Make code run in parallel

• Automatically debug code

Answer explanation

Encapsulation in OOP is primarily used to hide implementation details, allowing for a clear interface while protecting the internal state of an object. This promotes modularity and reduces complexity in code management.

Which data structure uses LIFO (Last In First Out)?

• Queue

• List

• Stack

• Array

• Dictionary

Answer explanation

A Stack is a data structure that follows the LIFO (Last In First Out) principle, meaning the last element added is the first one to be removed. This is in contrast to a Queue, which follows FIFO (First In First Out).
