Computer Science Concepts and Programming

Flashcards covering key terminology and concepts from computer science and Java programming as presented in the lectures.

Operating Systems

Software that manages computer hardware and software resources and provides common services for computer programs.

Interface

The means by which a user interacts with a computer or software application.

File System

A method of storing and organizing computer files and the data associated with them.

Processor

The component of a computer that performs calculations and executes instructions.

32-bit Processor

A processor that can handle 32 bits of data at a time.

64-bit Processor

A processor that can handle 64 bits of data at a time, allowing it to perform better and access more memory.

Application Security

Practices and measures taken to protect applications from threats throughout their lifecycle.

Software License

A legal instrument governing the use or redistribution of software.

Browser Security

Features and practices that protect the internet user while using a web browser.

System Hardening

Variable

A storage location paired with an associated symbolic name, which contains some known or unknown quantity of information.

Boolean Logic

A form of algebra that involves variables that have two possible values, typically true or false.

Array

A collection of items stored at contiguous memory locations, typically of the same data type.

Hash Map

A data structure that implements an associative array abstract data type, a structure that can map keys to values.

Recursion

A programming technique where a function calls itself in order to solve a problem.

Polymorphism

A feature of OOP that allows entities to be represented in many forms.

Interface

A shared boundary across which two or more separate components of a computer system exchange information.

Inheritance

A mechanism in object-oriented programming that allows one class to inherit the properties and behaviors of another class.
