Developers Dictionary

Developers, regardless of organization, often use a variety of terms to describe different concepts. Below is a list of definitions to help stakeholders better understand the language that Developers use.


Edge Computing

Edge computing is a distributed computing paradigm that brings computation and data storage closer to the location where it is needed, to improve response times and save bandwidth. It involves processing data near the source of data generation (such as IoT devices) rather than in a centralized data center, thereby reducing latency and bandwidth use.


In cloud computing, elasticity refers to the ability of a system to automatically scale computing resources up or down based on the current demands. This means adding or removing resources like CPU, memory, and storage to accommodate workload changes dynamically, ensuring that applications have the right amount of resources at any given time.

End User

An end user is the person who ultimately uses or is intended to use a product, service, or piece of software. End users are typically the target audience for a product and are distinct from those who create, manage, or maintain the product.

Event Driven

Event-driven architecture is a software design pattern in which the flow of the program is determined by events such as user actions (mouse clicks, key presses), sensor outputs, or messages from other programs/services. Systems and applications designed with this architecture respond to events as they occur, enabling reactive and responsive behavior.

Event Driven Language

An event-driven language is a programming language designed to facilitate the development of event-driven software. In such languages, the program’s flow is determined by events—specific actions or occurrences that the software responds to.

Executable Code

Executable code refers to computer instructions in a format that a computer’s CPU can directly execute. It is typically compiled from source code written in a high-level programming language into machine code or bytecode, which the computer’s hardware or a virtual machine can run.


Express.js is a minimal and flexible Node.js web application framework that provides a robust set of features to build web and mobile applications. It facilitates the development of server-side web applications by providing tools and utilities for handling HTTP requests, routing, middleware, and other common tasks.
