IB DP Computer Science — A2 Networks — Network fundamentals | SL | A2.1.2
📋 What You Will Learn
- Describe the purpose of five modern digital infrastructures: the internet, cloud computing, distributed systems, edge computing and mobile networks
- State the key benefits and limitations of each infrastructure
- Match real systems — the WWW, cryptocurrency blockchains, smart traffic lights, a school — to the infrastructures they run on
- Explain the trade-off between processing "at the edge" and "in the cloud"
- Evaluate which infrastructure suits a given scenario, using benefits and limitations as evidence
⚡ Why This Matters Electricity is an infrastructure: you plug in and power just arrives, generated somewhere far away.
