Edge computing basics in Intro to Computing - Cheat Sheet & Quick Revision

Recall & Review

beginner

What is edge computing?

Edge computing means processing data near where it is created instead of sending it far away to a central place. It helps make things faster and saves internet traffic.

beginner

Why is edge computing useful?

It reduces delay (latency), saves bandwidth, and can keep data private by processing it locally instead of sending it to a far server.

beginner

Give a real-life example of edge computing.

A smart security camera that detects motion and alerts you immediately without sending video to a far server first is using edge computing.

intermediate

What is the difference between edge computing and cloud computing?

Cloud computing processes data in big data centers far away. Edge computing processes data close to the device or user, near the 'edge' of the network.

beginner

What kind of devices are used in edge computing?

Devices like routers, gateways, small servers, or smart devices themselves can do edge computing by processing data locally.

What does edge computing mainly aim to reduce?

A Battery life

B Number of devices

C Delay in data processing

D Screen size

Edge computing reduces delay (latency) by processing data near the source.

Which of these is an example of edge computing?

A Processing data on a local smart thermostat

B Watching videos online

C Storing data on a USB drive

D Sending all data to a cloud server for processing

Processing data on a local device like a smart thermostat is edge computing.

Edge computing helps save which of the following?

A Number of users

B Electricity in data centers only

C Screen resolution

D Internet bandwidth

By processing data locally, edge computing reduces the amount of data sent over the internet, saving bandwidth.

Where is data processed in cloud computing compared to edge computing?

A Cloud: far away; Edge: locally

B Cloud: locally; Edge: far away

C Both locally

D Both far away

Cloud computing processes data in distant data centers; edge computing processes data near the source.

Which device is least likely to perform edge computing?

A Smartphone

B Cloud data center

C Local router

D Smart security camera

Cloud data centers are centralized and not considered edge devices.

Explain edge computing in your own words and why it is important.

Think about how your smart devices work faster by handling data nearby.

Describe a real-world example where edge computing is used and how it benefits users.

Imagine a device that reacts quickly without waiting for the internet.
