Computer science, Internet security and computer skills

From 34.78 $ /h

Answer to the many questions related to information technology.
Want to know how something works, or how you can prevent something.
You have come to the right place, I can teach you in all areas of information technology.
Below you see several questions to which I can give you a clear and straightforward answer. I can explain this to you at any level and we can go deep where you want it. Is your question not listed? Let me know. There are simply too many questions to write here.

How does the internet work?
How does a computer network work?
What is a DHCP server and how does DNS work?

How do I keep my identity hidden online?
What are cookies?
What does my computer store?
How does the Wehkamp site know that I like those pants?

How does Excel work? and Word? and Powerpoint?
What is a router?
How does WiFi work and can my neighbor on my network?
Do I have a strong password?
What is hacking?
How does a computer virus and ransomware work?
How does a firewall work?
What is blockchain?

I teach at different levels, if you are interested you can always send an email without obligation with your question. We can then make a personal study plan.
My specialization is internet security, but I got there by gaining knowledge within all facets of information technology. From system administration, network management and explaining the various functions in Windows or IOS to repairing the hardware of a PC.
I studied business informatics at the Hogeschool van Amsterdam. Nowadays I live on Curacao, but I can give great lessons via webcam. And through the possible use of team viewer or G + I can show on your computer how to configure a router, for example. Nothing is impossible ;-)

About Me

I am a 'tech junkie' I would love to read about the latest technologies all day and to pass this on to others while automating everything with a Raspberry PI.
Of course that's not possible, but I'm getting close. If I can make someone enthusiastic and convey what I have learned to you then my day is a success.
Enthusiasm is contagious, and a better infection than the virus that keeps us all over the world. Let me infect you with the most beautiful profession in the world, you will not regret it.

This course is designed for high school students who want to develop their computer skills, whether to start or deepen their knowledge. As a software engineering student at INSAT, I have a versatile background in computer science and a mastery of languages such as Python, Java, C, C++, JavaScript, PHP, HTML, and CSS.

We will cover the basics (office automation, programming) up to more advanced concepts corresponding to the Tunisian baccalaureate computer science program. I offer theoretical courses to fully understand the fundamental concepts, but I favor a practical approach for better assimilation.

Thanks to my past experience helping my classmates in high school, I know how to adapt my explanations according to the needs and pace of the student. Together, we will move towards your goals, whether it is to pass your exams or simply discover the world of IT.

Are you new to computers and want to learn how to use a computer independently? I offer courses adapted to your pace to master the essential basics.

👉 Understand and use a computer (Windows, macOS)
👉 Browse the Internet safely
👉 Use email and office tools (Word, Excel, etc.)
👉 Manage your files and folders efficiently
👉 Discover the basics of cybersecurity and data protection

Introduction to AI Assistants: Artificial intelligence (ChatGPT, etc.) to simplify your life

My approach: I adapt to your pace and needs. Every question is welcome, and we progress together until you feel independent.

See you soon, Chris

This class should help students learn how to write programs and, more importantly, how to think while programming.

It covers core ideas such as variables, conditions, loops, functions, and debugging, with explanations adjusted to the student’s level and chosen language.

The class welcomes all levels, from first-time programmers to students who want help with assignments or a deeper understanding. Students can request specific languages or topics, and lessons can follow school or university curricula.

Objective: To understand AI without fear, to use it to simplify one's life and to know how to identify digital traps.

1: Demystifying AI (What exactly is it?)
AI is not a movie robot: Difference between fiction and reality.

How it works (simply): The image of the "giant library": AI has read billions of books and uses them to predict the continuation of a sentence or create an image.

Where is it already present? Spell checkers, Netflix/YouTube suggestions, GPS, and voice assistants (Siri/Alexa).

2: Using AI to make life easier
Conversing with AI (ChatGPT, Claude, Gemini):

Ask him to write an administrative email or a complex letter.

Summarize a long newspaper article or document.

Plan a travel itinerary or find recipe ideas with what's left in the fridge.

AI for creativity and memory:

Generate images to illustrate a birthday card (Midjourney, DALL-E).

Using AI to restore or colorize old family photos.

3: Learning to "talk" to AI (The Art of the Prompt)
The context method: Why "Give me a cake recipe" is less effective than "I am allergic to gluten and I am hosting 4 people, give me a simple chocolate cake recipe".

The expert's role: Learning to tell AI "Act like a travel guide" or "Act like an expert gardener".

4: Precautions and Critical Thinking (The Survival Guide)
"Hallucinations": Understand that AI can make false claims with complete certainty (never take medical or legal advice from AI without verification).

Privacy protection:

Never give sensitive data (social security number, passwords, bank details) to an AI.

Knowing that everything we write to the AI is potentially used to train it.

Spotting "Deepfakes":

How to recognize a doctored image or video (details on the hands, strange reflections, slightly metallic voice).

Verify the information: the golden rule of cross-referencing sources.

5: Ethics and Impacts (To go further)
Copyright: Who owns an image created by AI?

The environmental impact: The water and energy consumption of AI servers.

The future: Will AI replace us or assist us?
