📌 Virtual Private Network Summary
A Virtual Private Network, or VPN, is a service that creates a secure, encrypted connection over the internet between your device and another network. This makes it appear as if you are accessing the internet from a different location. VPNs help protect your online privacy and keep your data safe from hackers or unwanted tracking.
🙋🏻♂️ Explain Virtual Private Network Simply
Think of a VPN like a secret tunnel between your computer and the internet. Anyone outside the tunnel cannot see what you are doing or where you are going online. It is like sending messages in a locked box instead of a postcard that anyone can read.
📅 How Can it be used?
A VPN can be used in a project to provide secure remote access to a company’s internal network for employees working from home.
🗺️ Real World Examples
A remote worker uses a VPN to securely connect to their company’s internal systems from a coffee shop. The VPN encrypts all data sent and received, so even if someone tries to intercept the Wi-Fi traffic, they cannot read any sensitive information.
A traveller in a country with restricted internet access uses a VPN to access websites and services that are otherwise blocked. By connecting through a VPN server in another country, they can browse the internet freely and securely.
✅ FAQ
What does a VPN actually do for me?
A VPN helps keep your online activity private by creating a secure tunnel between your device and the internet. This means your browsing, messages and other data are much harder for others to see, even on public Wi-Fi. It also lets you appear as if you are browsing from a different place, which can be handy for accessing websites or services that are restricted in your area.
Can I use a VPN to access shows or websites from other countries?
Yes, with a VPN you can make it look like you are browsing from another country. This can help you access TV programmes, streaming services or websites that might only be available in certain places. Just remember that some services may have rules about this, so it is good to check what is allowed.
Is it difficult to set up a VPN on my devices?
Setting up a VPN is usually straightforward. Many VPN services offer easy-to-use apps for computers, phones and tablets. You can often get started by downloading the app, signing in and choosing a location. Most people do not need any technical knowledge to begin using a VPN.

💡Other Useful Knowledge Cards
Retry Reasoning
Retry reasoning is a process where a system or program decides whether to try an action again after it fails. Instead of simply repeating the same step blindly, the system analyses why the failure happened and chooses the best way to proceed. This approach helps to avoid repeating mistakes and increases the chances of eventual success.
Legacy Application Refactoring
Legacy application refactoring is the process of improving the structure and design of old software systems without changing their core functionality. It involves updating outdated code, removing inefficiencies, and making the application easier to maintain and extend. Refactoring helps businesses keep their existing systems reliable and compatible with modern technologies.
Data Loss Prevention (DLP)
Data Loss Prevention (DLP) refers to a set of tools and processes designed to stop sensitive data from being lost, leaked, or accessed by unauthorised people. It monitors how data is used, moved, and shared within an organisation and outside of it. DLP systems can automatically block, alert, or encrypt data when a risk is detected, helping protect information such as personal details, financial records, or confidential business documents.
Cognitive Cybersecurity
Cognitive cybersecurity uses artificial intelligence and machine learning to help computers understand, learn from, and respond to cyber threats more like a human would. It analyses huge amounts of data, spots unusual behaviour, and adapts to new attack methods quickly. This approach aims to make cybersecurity systems more flexible and effective at defending against complex attacks.
Prompt Polishing
Prompt polishing is the process of improving and refining instructions given to an AI model to achieve clearer, more accurate, or more relevant responses. It involves editing the wording, structure, and detail of prompts so the AI better understands what is being asked. Effective prompt polishing helps avoid misunderstandings and increases the quality of the output generated by an AI.
