Digital systems work best when their parts communicate smoothly, just like in a natural ecosystem.
What is a Digital System?
Working Together
Parts that connect and cooperate.
Two Key Elements
Physical tools plus digital instructions.
Information Flow
Receives data and creates useful results.
Common Examples
Phones, tablets, and computers.
Parts of a Digital Device
1
Hardware
The physical parts you can touch.
2
Software
The invisible instructions that run the device.
How We Talk to Devices
Keyboard input
Tap and swipe
Speaking aloud
Using camera
Computer Basics

1
Processor
The main chip that runs all computer tasks.
2
Memory
Stores data and programs for quick access.
3
Network
Connects computers to share information.
What Our Devices Can Create
What Devices Make:
Pictures and videos
Music and sounds
Text documents
Instant messages
Real-World Uses:
Like watching shows at home, playing music on your phone, writing school papers, or sending a quick text to friends.
Natural Systems: What Are They?
Trees
Living plants that grow using sun, water, and ground.
Weather
How air, heat, and water change around us every day.
Ecosystems
Places where living things work together in nature.
What Plants Need to Grow
Sunlight
Plants use sunlight to grow
Water
Water helps plants live
Air (Carbon Dioxide)
Air helps plants make food
Nutrients from Soil
Soil provides plant nutrients
Plant Systems: Processing
1
Photosynthesis
Turns sunlight into food for the plant.
2
Roots
Drink water and collect food from the ground.
3
Leaves
Breathe in air to help the plant grow.
4
Teamwork
All plant parts help each other.
Plant Systems: Outputs
Oxygen Released
Photosynthesis creates oxygen as a byproduct.
Fruit Production
Fruits spread plant seeds for reproduction.
Seed Production
Seeds enable plants to grow in new areas.
Comparing Digital and Natural Systems
Need Inputs to Work
Systems require basic resources to start.
Process Information or Materials
They change inputs into useful things.
Create Outputs
Systems turn inputs into specific results.
Have Different Parts Working Together
Parts work as a team to reach a goal.
Inside a Digital Device
Connects components
Executes instructions
Stores data
Moves information
How Software Works
1
Instructions for Hardware
Software sends basic commands to computer parts.
2
Controls Device Actions
Software guides how a device should perform.
3
Examples
Software powers everyday tools like games, web browsers, and apps.
When Systems Fail
Digital Systems
Power disruptions stop digital systems.
Hardware failures cause total shutdown.
Natural Systems
Lack of water kills plants.
No sunlight prevents growth.
