AI, Cloud, Cybersecurity, Data — the buzzwords you nod at but never fully understood (until now).
🤖 What even is AI? (And why does it feel like it's everywhere all of a sudden?)
If you’ve used ChatGPT, Gemini, Copilot, or even just scrolled through Spotify recommendations lately, you’ve already met AI. Not in a sci-fi “robot takeover” kind of way, but in the quiet, invisible assistant that’s suddenly… everywhere.
But here’s the thing: AI isn’t magic. It’s not conscious. It’s not trying to replace you. It’s just really, really good at recognising patterns.
At its core, Artificial Intelligence means machines doing things that seem smart. Not emotionally smart. Not self-aware-smart. Just: “I’ve seen this before, and here’s what probably comes next.” That’s how your keyboard predicts your next word. That’s how Netflix knows you’re due for another sad-romantic-comedy binge.
Right now, most of what we use falls under Narrow AI — meaning it’s trained to do one task really well, like generating text, filtering spam, or recommending music. Behind the scenes? It’s just data + math + training algorithms doing their thing.
Whether or not you plan to build AI systems yourself, you’ll 100% interact with them in your daily work, your tools, and your feeds. So… better to know what’s going on, right?
Proof I’ve been working with AI since before it became a core subject
☁️ What even is the cloud? (And why is it the reason your Google Docs haven’t ghosted you yet?)
Let’s be real: “The cloud” sounds like some mystical place where our photos, files, and college assignments go to vibe eternally. But here’s the truth — the cloud is literally someone else’s computer, just sitting in a data centre… somewhere far away. That’s it.
The cool part? You don’t need to own that computer or even know where it is. You just open your Google Drive, or upload to Notion, or save a Canva draft, and boom, it’s there when you need it. From any device. Anywhere. No pen drive panic. No “oh crap, it was on my old laptop.”
Actually — true story — I once thought I’d lost my entire project because I accidentally messed up my files while editing. I panicked, closed all the tabs, and hit “don’t save changes.” A minute later, I reopened the doc, and… everything was still there. Because cloud storage had my back. Absolute life-saver.
Cloud computing basically means:
“Don’t store everything on your own device — let the internet handle it (safely, efficiently, and hopefully without deleting your stuff).”
It’s not just storage either. Companies use the cloud to run apps, train AI models, host websites, and manage data — all without setting up a million servers of their own.

🔐 Cybersecurity: Not just for hackers and hoodie-wearing coders
Last semester, I sat through a cybersecurity module thinking, “Okay but… am I really the kind of person who needs to know this?” Spoiler: yes. 100%. You are, too.
Because if you use a phone, a laptop, online banking, apps, email — literally anything connected to the internet — then understanding basic cybersecurity isn’t optional anymore. It’s just digital common sense.
Cybersecurity is how we protect our data, identity, accounts, and devices from being stolen, tracked, tricked, or wiped. It’s the reason:
- You need strong passwords (not your crush’s name + birth year)
- You use 2FA (yes, those annoying OTPs)
- You don’t click on “Congratulations! You’ve won ₹50,000!” emails at 2 am
We’re constantly connected — but we’re also constantly vulnerable. There are phishing attacks, malware infections, data leaks, ransomware, and more happening all the time.
And here's what I’ve learned: the goal isn’t to become paranoid. It’s to become aware. Aware enough to not get tricked, hacked, or locked out of your own files.
Because in 2025? Digital hygiene is real hygiene.
📊 Data: The fuel behind literally everything (including your wrong predictions)
AI? Needs data. Cloud storage? Holds data. Cybersecurity? Protects data. Your search history, playlists, screen time, how long you hovered over that meme before scrolling? Yup. Data.
But here’s the thing no one tells you: data isn’t just numbers. It’s not just “big tech” tracking you. It’s the raw material for every system we rely on — and if it’s messy, biased, or unbalanced, everything built on top of it fails.
Ask me how I know 😭
While working on a sentiment analysis project using the Naive Bayes algorithm, I had this seemingly great dataset of customer reviews. But guess what? It had way more positive reviews than negative ones. The model learned to say “positive” almost every time — even when it clearly wasn’t. Why? Because the data was skewed. And honestly, no algorithm can fix that.
This is why understanding data matters — not just to code, but to build better systems, make ethical decisions, and ask the right questions.
In the world we’re moving into, data is power. But only if it’s collected, cleaned, and handled right.
When the model is too optimistic for its own good 😅
📩 Final Note
This is Part 1 of Tech Demystified. These are the buzzwords we hear all the time, but rarely pause to understand. And the truth is? You don’t need a tech degree to get this stuff — you just need it explained in a way that makes sense.
Next Sunday, we go deeper: APIs, UX, Web3, and automation — aka the tech that connects, designs, and powers the tools we use every day.
Until then: be curious, stay aware, and maybe… check your passwords 😅
