IT Vocabulary Words

A running list of terms to memorize for succes

Online-First Model

Prioritizes internet-based platforms for customer engagement, sales, and operations over traditional brick-and-mortar storefronts

Content Management System (CMS)

Software that allows users to create, manage, store, and publish digital content without advanced coding knowledge.

Chief Digital Officer (CDO)

A senior executive responsible for driving an organization's digital transformation. They bridge the gap between business and technology.

Network Architect

Someone who designs and builds complex data communication networks—including LANs, WANs, and cloud environments.

Star Topology

A network setup where all devices (nodes) connect individually to a central hub or switch. Data passes through this central point, making it the standard design for modern Local Area Networks (LANs) like home Wi-Fi and office Ethernet configurations.

Nodes

Refers to a connection point, intersection, or individual unit within a larger system.

NIC (Network Interface Card)/ Network Adapter/ LAN Card

The hardware component that allows a device to connect to a network. It translates data between the computer and the network, enabling wired (Ethernet) or wireless (Wi-Fi) communication.

Switch

A hardware device that connects multiple devices—like computers, printers, and servers—together within a single local area network (LAN).

Supercomputer

An ultra-powerful computing system designed to perform complex calculations at unprecedented speeds by linking thousands of individual nodes together.

Social Engineering

The psychological manipulation of people into performing actions or divulging confidential information.

Hierarchical Structure

A pyramid-style arrangement where authority flows top-down, with a single entity or small leadership group at the apex and subordinates arranged in subsequent tiers.

VPN Router

A central networking device with VPN capabilities.

VPN (Virtual Private Network)

A service that secures your internet connection and protects your privacy. It routes your online traffic through an encrypted, remote server, masking your IP address and preventing third parties from intercepting or tracking your data.

Enterprise Resource Planning System

Integrated software platforms used by organizations to manage and automate core business processes. By consolidating data from finance, HR, manufacturing, supply chain, and procurement into a single database they provide a unified "source of truth".

Cloud Computing

The on-demand delivery of computing resources—including data storage, servers, databases, networking, and software—over the internet.

Version Control System

Software that tracks and manages changes to files over time, keeping a structured history of modifications. It allows multiple users to collaborate on projects without overwriting each other's work and enables you to instantly revert files to previous versions.

Metedata

Defined as "data about data." It provides information that describes, explains, or contextualizes the content, quality, and characteristics of an original dataset, file, or resource

Data Management System

Software infrastructure designed to collect, organize, secure, and store an organization's data throughout its lifecycle. It acts as a central hub—combining database management systems (DBMS), data warehouses, and integration tools—so users can easily retrieve information, automate workflows, and drive decision-making.

Mesh Topology

A network setup where devices (nodes) are interconnected, allowing data to travel across multiple pathways. Much like a spiderweb.

Iterative

A process of repeating a series of steps, usually with the goal of continuous improvement. Each repetition builds upon the findings of the previous one, gradually refining a product, project, or idea until the desired outcome is achieved

Matrix Structure

A workplace where multiple departments create teams to work on a specific project. The teams benefit from a variety of skill sets to ensure work gets done to the best of its ability.

IT Governance

A foundational corporate framework that ensures an organization's technology strategies align with its overarching business goals. It establishes policies, decision-making structures, and accountability measures to mitigate risks, optimize resources, and drive measurable value from IT investments.

WAN (Wide Area Network)

A large-scale computer network spanning a broad geographic area—such as a city, country, or the entire globe—typically used by organizations to connect multiple smaller local networks together.

LAN (Local Area Network)

A computer network that interconnects devices within a limited physical area, such as a home, school, or office building. It allows computers, printers, and smart devices to communicate, share files, and access a central internet connection using Ethernet cables or Wi-Fi.

Flat Organizational System

Eliminates middle management, leaving few or no layers between frontline employees and executives. This horizontal model pushes decision-making to the edges of the company, which boosts agility, cuts overhead costs, and empowers staff.

Integrated Development Environment

A software application that combines essential developer tools—such as a code editor, debugger, and build automation system—into a single graphical interface. It boosts productivity by preventing the need to manually configure and switch between separate programs.

Enterprise Architecture Framework (EAF)

A structured set of guidelines, principles, and models used to align an organization's business strategy with its IT infrastructure. It establishes a standardized blueprint to plan, design, and govern enterprise-wide operations, digital transformation, and systemic change.

Software Development Strategies

High-level plans dictating how a project’s resources are applied, approached, and delivered. Successful execution relies on aligning the right methodology (such as Agile or Waterfall) with proper architectural design, robust automated testing, and ongoing talent development to ensure scalable and maintainable products

Agile

A software development strategy that prioritizes adaptability, continuous user feedback, and incremental releases (e.g., Scrum, Kanban). Ideal for fast-moving markets where requirements frequently evolve.

Waterfall

A software development strategy that is a sequential, plan-driven approach where each phase (design, build, test) must be completed before the next begins. Best suited for highly regulated environments with fixed, predictable requirements.

DevOps

A software development strategy that integrates development and IT operations to shorten the development lifecycle. It heavily relies on continuous integration and continuous deployment (CI/CD) to release small batches of code automatically and frequently

Compiled Languages

Translates human-readable source code directly into machine-executable code before running.

Examples: C and C++, Rust, Go, Swift
