Getting Started / Whakataki (Prior Knowledge Required)

You don't need any special prior knowledge to begin this topic! Just bring your curiosity about the technology you see and use every day. This is a great place to start your Digital Technologies journey.

What is a Digital Device?

A digital device (pūrere matihiko) is any piece of hardware that processes or stores information using binary code (0s and 1s). These devices take information, do something with it, and often give us back new information or perform a task. They are designed and built by humans to help solve problems or make our lives easier.

Think of it like a translator: digital devices translate our commands and information into their own binary language, process it, and then translate the results back into something we can understand.

Examples of Digital Devices:

Smartphones
Laptops and Desktop Computers
Tablets
Smart TVs
Calculators
Digital Cameras
Traffic Lights (many are computer-controlled)
Smart Doorbells
Gaming Consoles
GPS Devices
Embedded Systems (like the computer chip in a washing machine, a smart watch, or a car's engine control unit)

All of these devices, from the simplest calculator to a powerful supercomputer, rely on digital information and processing.

How It Works / Me Pēhea te Mahi

The needs of the At a very basic level, every digital device does three things:

Takes Input: It receives information or instructions from somewhere (like a tap on a screen, a button press, a voice command, or data from a sensor).
Processes Data: Its internal hardware components (like a Central Processing Unit - CPU) use software (instructions) to work with that information. They perform calculations, follow steps (algorithms), or manipulate the data. This is where the binary language (0s and 1s) is used at a fundamental level.
Produces Output: It sends out information or performs an action (like displaying an image on a screen, playing a sound, vibrating, or turning a light on).

This simple Input → Process → Output cycle is what almost all digital devices do!

Activities / Ngā Mahi

Activity 1: Digital Device Scavenger Hunt:

Task: Look around your home, school, or even outside (safely, with permission if needed!). Find at least five different digital devices. Try to find a mix of common and perhaps less obvious ones (like a digital thermometer or a remote control).
Activity: For each device:
- Name the device.
- Briefly describe its main purpose.
- Explain why you think it's a digital device (what kind of information does it process or store?).
Why this activity helps: This helps you identify digital devices and understand their purposes (DDDO PO1).
Evidence: Create a Google Doc or Google Slide with a list of your five devices and your descriptions. You could even include photos if you wish!

Activity 2: The "Smart" Object:

Task: Think of an everyday, non-digital object (e.g., a pen, a chair, a plant pot, a spoon, a shoe).
Activity: Brainstorm how you could turn it into a "smart" digital device by adding digital capabilities. What would be its inputs, what would it process, and what would be its outputs?
Why this activity helps: This helps you understand the purpose of digital devices and how they function (DDDO PO1).
Evidence: In a Google Doc or Google Slide, describe your "smart" object and its basic Input → Process → Output cycle.

Assessment / Te Aromatawai

This section is your opportunity to demonstrate your overall understanding of Hardware and how it underpins digital concepts, as required by the Progress Outcomes.

Task: Choose one common digital device (e.g., a smartphone, a laptop, or a smart appliance).

Activity: Create a short report (e.g., 1-2 pages in Google Docs) or a concise presentation (e.g., 3-5 slides in Google Slides) that:

Identifies at least three key internal hardware components of your chosen device.
Explains the purpose and basic function of each of these identified components.
Explains how these hardware components work together (their mechanisms) to enable the device to perform its main function (e.g., making a call on a phone, browsing the internet on a laptop).
Discusses how the mechanisms of this hardware underpin the digital device's capabilities, linking to CT Progress Outcome 7 and 8.

Evidence: Submit your Google Doc report or Google Slide presentation to Google Classroom as instructed by your kaiako.

Key Takeaways / Mātauranga

Digital devices are physical tools that process and store information using binary code.
They all follow a basic Input → Process → Output cycle.
Digital devices are designed and built by humans to achieve specific purposes.
