It Specialist Software Development Concepts Study Guide

What is the purpose of a programming language?

• To provide entertainment for programmers

• To confuse computers with random commands

• To make computers self-aware

• To provide a set of instructions for a computer to execute specific tasks or operations.

Explain the different phases of the Software Development Life Cycle.

• Planning, Analysis, Design, Implementation, Testing, Deployment, Maintenance

• Coding, Debugging, Documentation, Deployment, Maintenance

• Analysis, Design, Testing, Deployment, Support

• Initiation, Execution, Monitoring, Closure

What is a Version Control System and why is it important in software development?

• Version Control Systems are only important for large companies in software development.

• A Version Control System is used to store passwords securely in software development.

• Version Control Systems slow down the development process in software development.

• A Version Control System is important in software development because it helps track changes, facilitate collaboration, track bugs, and revert to previous versions if needed.

Describe a common debugging technique used in software development.

• Rubber duck debugging

• Code review

• Print debugging

• Breakpoint debugging

What are the key principles of Object-Oriented Programming?

• encapsulation, inheritance, polymorphism

• modulation

• overloading

• abstraction

Name three popular programming languages used in software development.

• Ruby

• C++

• Java, Python, JavaScript

• Swift

How does version control help in collaboration among team members?

• Version control creates unnecessary barriers for team members to access files, hindering collaboration.

• Version control does not track changes made by team members, leading to confusion and errors in collaboration.

• Version control only allows one team member to work on a file at a time, slowing down collaboration.

• Version control provides a centralized platform for team members to work on files together, ensuring everyone is working on the most up-to-date version and enabling efficient collaboration.

What is the difference between procedural programming and object-oriented programming?

• The main difference is the approach to organizing code and data: procedural programming uses functions to operate on data, while object-oriented programming uses objects that contain data and methods.

• In procedural programming, data is stored in classes, while in object-oriented programming, data is stored in functions.

• Procedural programming uses objects, while object-oriented programming uses functions.

• The main difference is the syntax: procedural programming is more verbose than object-oriented programming.

What are the advantages of using an Integrated Development Environment (IDE) for software development?

• IDEs are only suitable for beginners

• IDEs slow down the development process

• IDEs lack customization options

• Centralized platform for coding, debugging, and testing software with features like code completion, syntax highlighting, and project management tools.

Explain the concept of inheritance in Object-Oriented Programming.

• Inheritance is a mechanism where a subclass inherits properties from a superclass.

• Inheritance is a mechanism where a new class inherits properties and behaviors from an existing class. The existing class is called the superclass or parent class, and the new class is called the subclass or child class.

• Inheritance is a mechanism where a class inherits properties from a child class.

• Inheritance is a mechanism where a class inherits properties from an interface.
