Unit 1: Introduction to Digital Technology

Vocabulary flashcards covering core computing concepts, hardware and software components, computing device types, environmental impacts, and ethical digital technology practices.

Information Technology (IT)

A system that processes, stores, and transfers information in various forms such as words, numbers, pictures, sound, or video using binary digits 0 and 1.

Data

Information stored and processed in an IT system using binary digits (0 and 1).

Hardware

The physical devices and components that make up a computer system, including internal parts and peripheral devices.

Peripheral Devices

Components connected to a computer system (such as mice, keyboards, scanners, cameras, and microphones) that allow information to be entered or retrieved.

Software

The instructions or computer programs that a computer follows to perform tasks and manipulate data.

Operating System (OS)

Software that establishes a basic software environment on a computer to allow software applications to be installed and run.

Central Processing Unit (CPU)

The component that retrieves instructions or data from RAM, processes binary instructions, and directs other system components to perform actions.

Personal Computer (PC)

A computing device designed for individual users, originating from the IBM PC (1981) based on Intel's x86 CPU platform.

Workstation

A powerful desktop PC designed for heavy, resource-intensive computing tasks.

Server

A hardware or software system that provides services to multiple users on a network, utilizing reliable components with built-in redundancy.

Internet of Things (IoT)

Everyday devices (such as fridges, cameras, and thermostats) embedded with computing and networking capabilities.

Education Before Technology

A learning environment where students gathered around a blackboard to learn directly from a teacher through writing, reading, and repetition without digital tools.

Education With Technology

A modern classroom setting where students use computers, digital tools, and projector screens for interactive, visual, and connected learning.

Metal Information Research Chart

A structured table used to research key facts about technology metals, including mining methods, locations, product uses, required quantities, health/environmental concerns, and sources.

Impacts of Digital Issues Diagram

An overview chart categorizing digital technology issues based on how they affect individuals (privacy loss, cyberbullying, addiction) versus society (digital divide, misinformation, algorithmic bias).

Responsible & Ethical Tech Use Framework

A guidelines chart outlining key principles for digital use, including Respect, Awareness, Safety, Fairness & Inclusion, Deep sources, and Accountability.

Digital Divide

Unequal access to digital devices, internet connection, and digital skills, leading to unequal learning opportunities across society.

Algorithmic Bias

Discrimination or systematic unfair treatment and stereotypes originating from AI-based systems.

Digital Footprint

Online activity that leaves a permanent record of a user's digital presence.

Digital Consent

Approval required before using or accessing another person's data, images, or accounts.
