Programming Concepts & Application Development Flashcards

What is a 'deadlock' in concurrent programming?

Answer: A situation where two or more processes are each waiting for the other to release a resource

A deadlock occurs when two or more processes are permanently blocked, each waiting for a resource held by the other.

Which HTTP method is typically used to update an existing resource in a RESTful API?

Answer: PUT

In the context of software architecture, what is 'separation of concerns'?

Answer: Dividing a program into distinct sections, each addressing a separate concern

Separation of concerns is a design principle where a program is divided into distinct sections, each responsible for a specific aspect of functionality.

What type of error occurs at runtime when a program attempts to access memory it is not authorized to use?

Answer: Segmentation fault

A segmentation fault is a runtime error raised when a program tries to access a memory location it is not permitted to access.

Which of the following best describes 'recursion' in programming?

Answer: A function that calls itself to solve a smaller instance of the same problem

Recursion is a programming technique where a function calls itself with a simpler or smaller input until it reaches a base case.

What is the primary purpose of an Application Programming Interface (API)?

Answer: To define protocols and tools for building and integrating software components

An API defines a set of rules and protocols that allow different software applications to communicate and share functionality.

In object-oriented design, what is 'abstraction'?

Answer: Hiding the complex implementation details and exposing only the necessary interface

Abstraction simplifies complexity by exposing only the relevant details of an object and hiding its internal implementation.
