Career and Technology Studies Grades 10-12

Take an online adventure in Interland - these four challenging games let students put the key lessons of digital safety into hands-on practice.

Cybersecurity is a set of techniques to protect the secrecy, integrity, and availability of computer systems and data against threats. We'll talk through some strategies we use like passwords, biometrics, and access privileges to keep our information as secure.

Today we're going to talk about hackers and their strategies for breaking into computer systems.

Today we’re going to talk about how to keep information secret, and this isn’t a new goal. From as early as Julius Caesar’s Caesar cipher to Mary, Queen of Scots, encrypted messages to kill Queen Elizabeth in 1587, theres has long been a need to encrypt and decrypt private correspondence.

Information from the Canadian Government about the basic steps everyone should take related to cyber security

Advice, guidance, and information developed by cyber experts from the Canadian Centre for Cyber Security, based on their unique access and vantage point.

How aware are you of your digital dossier? Watch this time line of Andy's lifespan and find out when your digital dossier starts and how it grows

This Canadian website exists to help teens to remove inappropriate pictures of themselves that are being shared on the Internet.

Wi-Fi hotspots in coffee shops, airports, and hotels are convenient, but may not be secure. This video provides tips to help protect your personal information.

This interactive takes you through 11 situations during which you may be vulnerable to ID theft. During each section (or at the end) you can review the "read and learn book" to get some helpful advice about protecting your identity and privacy.

This organization has a collection of resources (privacy, online safety) about keeping your family and your devices secure.

One way that the Canadian Cyber Centre contributes to improving the cyber security ecosystem is by releasing some of its cyber defence tools to the open-source community

The Internet of Things gives us access to the data from millions of devices. But how does it work, and what can we do with all that data?

A hidden network of fiber cables links our planet and makes the internet possible. What is fiber optics, how does it work, and how is it evolving?

Every time you use the Internet to watch a movie, listen to music, or check directions, your device is using the language of binary code. This video explains how colours, numbers, letters and music are conveyed using only the numbers 1 and 0.

In many ways, our memories make us who we are, helping us remember our past, learn and retain skills, and plan for the future. And for the computers that often act as extensions of ourselves, memory plays much the same role.

So, what exactly does airplane mode do? Lindsay DeMarchi explains the setting's importance for the networks around you.

Today we’re going to create memory! Using the basic logic gates we discussed in episode 3 we can build a circuit that stores a single bit of information, and then we’ll show you how we can construct the modern random-access memory, or RAM.

Today we’re going to build the ticking heart of every computer - the Central Processing Unit or CPU. The CPU’s job is to execute the programs we know and love - you know like GTA V, Slack... and Power Point.

Today we’re going to take our first baby steps from hardware into software! Using that CPU we built last episode we’re going to run some instructions and walk you through how a program operates on the machine level.

Memory and storage are different things but both hold data in your computer. Data written to storage, like your hard drive, is a little different, because it will still be there even if the power goes out

Often files are way too large to be easily stored on hard drives or transferred over the Internet - the solution, unsurprisingly, is to make them smaller. We use a process called compression.

Today, we're going to discuss the critical role graphical user interfaces, or GUIs played in the adoption of computers.

Today we start a three episode arc on the rise of a global telecommunications network that changed the world forever. We’re going to begin with computer networks, and how they grew from small groups of connected computers on LAN networks to eventually larger worldwide networks

Today, we're going to talk about how the Internet works. Specifically, how that stream of characters you punch into your browser's address bar, like "youtube.com", return this very website.

Today we’re going to discuss the World Wide Web - not to be confused with the Internet, which is the underlying plumbing for the web as well as other networks.

In our SERIES FINALE of Crash Course Computer Science we take a look towards the future! In the past 70 years electronic computing has fundamentally changed how we live our lives, and we believe it’s just getting started.

This video explains network theory and how networks keep us connected. Learn how we live within a web of networks, not just on social media. How does Googling a single word provide millions of results?

Draw.io is a great tool for creating flowcharts to illustrate program flow or ideas. It's simple to use - click on Help to get an introduction video and tips.

Lucidchart is an open access diagramming application that makes it easy to diagram complex relationships like those that exist in networks.
