  "android": [
    { "term": "ADB", "explanation": "Imagine your computer and your Android phone are best friends who speak a secret language nobody else understands. ADB is that secret language. You type something on your computer, and your phone just... does it. No touching the phone, no tapping icons. It's like being able to whisper instructions to your toy from across the room and watching it obey." },
    { "term": "Fastboot", "explanation": "Sometimes your phone isn't fully awake yet, it's in a super deep sleep mode before the normal Android part even starts. Fastboot is a secret side door you can sneak through while it's in that deep sleep, so you can hand it new stuff to wake up with, before it even opens its eyes." },
    { "term": "Root", "explanation": "Normally your phone only lets you play in the kiddie section of the playground, the swings and the slide, nothing more. Getting Root is like being handed the master key to the ENTIRE playground, including the shed with all the tools, the staff-only areas, everything. You can go anywhere and touch anything now." },
    { "term": "Bootloader", "explanation": "Think of the bootloader as a strict security guard standing at the front door of your phone. Every single morning when the phone wakes up, the guard checks: 'Is this the official stuff that's allowed in here?' If you unlock the bootloader, you're basically telling the guard to take a coffee break and let anyone in, official or not." },
    { "term": "Recovery Mode", "explanation": "This is a special hidden room in your phone that you only visit when something has gone wrong, like a tiny emergency room just for your phone. You don't hang out there normally, but when the phone gets sick or confused, you go to Recovery Mode to patch it up and send it back out into the world." },
    { "term": "Bricking (ladrillar)", "explanation": "You know how a brick just sits there and does absolutely nothing useful? When something goes horribly wrong while messing with a phone and it stops turning on completely, people say you 'bricked' it, because now it's about as useful as a literal brick. It won't light up, won't buzz, won't do anything at all." },
    { "term": "APK", "explanation": "An APK is like a little lunchbox that contains everything an app needs to survive on your phone: its pictures, its instructions, its little tools, all packed neatly into one box. When you install an app, you're really just handing your phone this lunchbox and saying 'here, unpack this and set it up.'" },
    { "term": "Sideloading", "explanation": "Normally you get apps from the official app store, like walking through the front door of a shop. Sideloading is climbing in through a side window instead, you're installing an app directly, skipping the store completely. It works, but you're not using the door everyone else uses." },
    { "term": "Debloating", "explanation": "Phones often come stuffed with apps nobody asked for, like getting a toy box full of toys you never wanted to play with. Debloating means going through that toy box and throwing out all the junk you'll never touch, so there's more room and the phone runs faster and feels lighter." },
    { "term": "Custom ROM", "explanation": "Imagine your phone came dressed in an outfit picked by the company that made it. A Custom ROM is like giving your phone a completely new outfit and personality made by a totally different group of people, sometimes it looks nicer, works differently, or adds features the original company never gave you." },
    { "term": "Magisk", "explanation": "Once your phone has Root, which is like having the master key, Magisk is a magical invisible cloak you can put over that key. It lets your phone do special root tricks while making some apps think nothing special is going on at all, hiding the fact you have all that extra power." },
    { "term": "MediaTek BROM", "explanation": "Some phones use a special kind of brain chip called MediaTek, and those chips have an extra-extra secret door built super deep inside, even deeper than the Fastboot door. BROM is that emergency backup entrance you use when everything else is locked and the phone seems totally unresponsive." },
    { "term": "scrcpy", "explanation": "This tool lets you see and control your phone's screen right from your computer, like your computer has a magic mirror that not only shows what's happening on your phone, but also lets you tap and type on it using your mouse and keyboard instead." },
    { "term": "Boot Animation", "explanation": "It's the little cartoon or logo animation you watch play out when you first turn your phone on, before your home screen full of apps shows up. It's kind of like the opening credits of a movie, a small show before the real thing starts." },
    { "term": "Kernel", "explanation": "The kernel is the tiny brain sitting at the very center of the phone that translates between the operating system and all the physical parts, the screen, the buttons, the camera, the speakers. Without it, all those parts would just sit there confused, with nobody telling them what to do." },
    { "term": "OTA Update (Over-The-Air)", "explanation": "OTA stands for Over-The-Air, which just means your phone downloads and installs updates all by itself using the internet, no cables, no plugging into a computer. It's like your phone quietly reading a new book of instructions delivered through the air while you're not even watching." },
    { "term": "TWRP", "explanation": "TWRP is a friendly little toolbox with buttons and menus that shows up when your phone is in Recovery Mode. Instead of typing complicated commands, you get to tap on things like 'install this' or 'backup that,' making the whole emergency-room visit a lot less scary." },
    { "term": "Play Protect", "explanation": "Think of Play Protect as an invisible security guard that Google quietly stations inside your phone. It keeps an eye on every app you install, sniffing around for anything sneaky or dangerous, and warns you before something bad has a chance to cause trouble." }
  ],
  "ios": [
    { "term": "Jailbreak", "explanation": "Apple normally keeps the iPhone living inside a very pretty, very locked cage, safe, controlled, and limited to only what Apple allows. Jailbreaking means picking the lock on that cage and letting the phone step outside, so it can do things Apple never intended or wanted it to do." },
    { "term": "IPA", "explanation": "Just like Android has the APK lunchbox, iPhones have their own version called an IPA. It's a packaged bundle containing everything an app needs to live and run on your iPhone, all its code, images, and settings, wrapped up neatly in a single file." },
    { "term": "Sandbox", "explanation": "Picture every app on your iPhone playing in its own private sandbox in a playground. Each app can build its own sandcastles and play with its own toys, but it's not allowed to reach over into another app's sandbox and mess with its stuff, unless it's given special permission first." },
    { "term": "TestFlight", "explanation": "TestFlight is like a backstage rehearsal room for apps that aren't quite ready for the big show yet. Developers invite you in to try out an app before it officially opens to everyone, so you get to play with it early and help find any mistakes before the real premiere." },
    { "term": "SIP (System Integrity Protection)", "explanation": "SIP is a giant, heavy padlock that Apple welds onto the most important and delicate parts deep inside the operating system. It's so strict that even you, the owner of the phone, aren't normally allowed to touch those protected parts, keeping them safe from accidental damage or tampering." },
    { "term": "iCloud", "explanation": "Think of iCloud as a magical backpack that floats up in the sky, always ready to hold copies of your photos, notes, and files. If you ever drop your phone in a lake or lose it, that backpack in the sky still has everything safe and sound, waiting for you to grab it again." },
    { "term": "App Store Review", "explanation": "Before any app is allowed to appear in the App Store for you to download, a team of real people at Apple actually looks it over first, checking that it's not sneaky, harmful, or broken. It's like a strict teacher grading homework before letting it go on display for everyone to see." },
    { "term": "DFU Mode", "explanation": "DFU Mode is the deepest, most secret state an iPhone can be in, so deep it's almost like putting the phone on pause before it's even really 'born' as a working device. It's used to fix phones from the very ground up when nothing else has worked." },
    { "term": "Provisioning Profile", "explanation": "This is a special wristband-like permission slip that says 'yes, this particular app is allowed to be installed on this particular iPhone.' Without the right wristband, security won't let the app in, just like a bouncer checking passes at the door of an exclusive event." },
    { "term": "Swift", "explanation": "Swift is the language that programmers speak when they're writing instructions for iPhone and Mac apps. It's kind of like how English or Spanish lets people communicate with each other, Swift lets programmers communicate clearly with the phone about exactly what they want it to do." },
    { "term": "Face ID", "explanation": "Face ID is a clever little camera system that studies your face closely enough to recognize you, the real you, and only you. Once it's sure it's really your face looking at the screen, it unlocks the door and lets you right into your phone." },
    { "term": "Airdrop", "explanation": "Airdrop is like tossing an enchanted paper airplane between two nearby iPhones, except instead of paper, it's carrying photos, videos, or files. No cables, no internet connection needed, just a little bit of wireless magic floating through the air between two devices close together." }
  ],
  "windows": [
    { "term": "Registry", "explanation": "The Windows Registry is like an enormous library filled with tiny notecards, and each notecard says something specific about your computer: what your wallpaper looks like, which apps are installed, how your mouse should behave. Windows constantly flips through this library to remember how everything should be set up." },
    { "term": "BSOD (Blue Screen of Death)", "explanation": "Sometimes Windows gets so confused and overwhelmed that it just can't keep going anymore. When that happens, the whole screen turns a sad shade of blue and shows you a message basically saying 'I'm sorry, something went really wrong, and I have to stop right now.' It's the computer's dramatic way of throwing in the towel." },
    { "term": "Task Manager", "explanation": "Task Manager is like a classroom full of little students, where each student is a program running on your computer. Some behave nicely, others act up and cause trouble. Task Manager lets you peek in on all of them and, if one is misbehaving, send it straight to timeout by closing it down." },
    { "term": "DLL", "explanation": "DLLs are like shared toolboxes sitting in a common area that lots of different programs can borrow tools from, instead of every single program having to carry around its own complete set of tools. It saves space and keeps things tidy, since everyone shares instead of duplicating." },
    { "term": "PowerShell", "explanation": "PowerShell is a way of talking directly to Windows by typing out commands, almost like casting spells with very precise magic words, instead of clicking around with your mouse. Once you know the right words, you can make the computer do powerful things really quickly." },
    { "term": "Safe Mode", "explanation": "Safe Mode is Windows putting on its simplest, comfiest pajamas and only turning on the bare essentials it truly needs to function. This stripped-down version helps you fix problems without any of the extra, potentially troublesome stuff getting in the way and causing more confusion." },
    { "term": "Driver", "explanation": "A driver is a patient little translator standing between Windows and a piece of hardware, like your printer, mouse, or webcam. Windows speaks one language and the hardware speaks another, and without this translator quietly helping out, the two of them simply wouldn't understand each other at all." },
    { "term": "Windows Update", "explanation": "Windows Update is basically Windows going to school over the internet to learn new things and fix its own mistakes. It downloads lessons about security fixes, new features, and bug patches, then applies everything it learned so your computer becomes a little bit better and safer." },
    { "term": "Group Policy", "explanation": "Group Policy is like a strict set of house rules that a computer's administrator, often an IT manager at a company, sets for everyone using the machine. Rules like 'you're not allowed to install games' or 'this wallpaper is mandatory' all get enforced automatically, whether you like it or not." },
    { "term": "WSL (Windows Subsystem for Linux)", "explanation": "WSL is like inviting a friendly little penguin, representing Linux, to move in and live comfortably inside the house that Windows built. Now both operating systems can share the same home, working side by side, letting you use Linux tools without ever leaving Windows." },
    { "term": "System32", "explanation": "System32 is an extremely important room deep inside the Windows house, packed with delicate, load-bearing pieces that keep the whole structure standing up. If you go poking around in there carelessly and break something, the entire house of Windows can come crashing down around you." },
    { "term": "Explorer.exe", "explanation": "Explorer.exe is like a friendly waiter walking you through the restaurant of your computer, showing you all your folders and files whenever you open a window. It's the thing quietly working behind the scenes to display your desktop, taskbar, and file browser." }
  ],
  "linux": [
    { "term": "Kernel", "explanation": "The kernel is the little brain sitting right at the center of the whole system, connecting the operating system to every physical piece of the computer, like a conductor standing in front of an orchestra, making sure every instrument plays its part at exactly the right moment." },
    { "term": "Distro (Distribution)", "explanation": "Linux itself is kind of like a basic recipe, and a Distro is what happens when different cooks around the world take that same recipe and make it their own way. Fedora, Ubuntu, and Arch are all cooking from the same base recipe, but each one adds its own flavor and style." },
    { "term": "Terminal / Shell", "explanation": "The terminal is like writing a very precise letter directly to your computer, using exact words instead of clicking on pretty little icons and buttons. You type exactly what you want, hit enter, and the computer does precisely that, nothing more, nothing less." },
    { "term": "sudo", "explanation": "Typing sudo before a command is like saying a magic password that lets you temporarily act as the boss of the entire computer, even if you're normally just a regular user. It's a way of saying 'trust me, I know what I'm doing, let me do this important thing.'" },
    { "term": "Package Manager", "explanation": "A package manager is like a friendly little corner store living inside your computer, where you can walk up and ask for an app by name, and it goes and fetches it, sets it up properly, and even keeps it updated later, all without you having to hunt around for it yourself." },
    { "term": "Systemd", "explanation": "Systemd is like the stage manager backstage at a play, deciding exactly which actors, meaning which programs and services, walk out on stage first when the computer boots up, making sure everything starts in the right order so the whole show runs smoothly." },
    { "term": "GNOME / KDE (Desktop Environment)", "explanation": "GNOME and KDE are like different outfits and interior decorating styles you can dress Linux up in. The underlying computer works the same either way, but choosing GNOME or KDE completely changes how everything looks, feels, and behaves when you're clicking around." },
    { "term": "Filesystem (ext4, btrfs...)", "explanation": "A filesystem is the specific way your computer organizes its drawers and shelves to store all your files neatly, so it can find exactly what it's looking for quickly instead of digging through a messy pile. Different filesystems like ext4 or btrfs are just different organizing styles." },
    { "term": "Root user", "explanation": "The root user is like the ultimate boss of the entire computer, someone who's allowed to touch, change, or even delete absolutely anything, including the deep, sensitive stuff that could break everything if handled carelessly. With great power comes great responsibility, as they say." },
    { "term": "Permissions (chmod)", "explanation": "Permissions are like rules taped onto boxes around the house saying who's allowed to open them: this box only Mom can open, that box everyone can look inside but not touch, this other box nobody but the owner can even peek into. chmod is how you change those rules on the boxes." },
    { "term": "Cron", "explanation": "Cron is like setting an alarm clock for your computer that goes off at specific times to remind it to do certain chores, all on its own, even while you're fast asleep or off doing something else entirely. You set it once, and it faithfully repeats the task forever." },
    { "term": "Bash Script", "explanation": "A bash script is like writing out a numbered to-do list of instructions and handing the whole list to the terminal at once, instead of typing each command one at a time yourself. The terminal reads down the list and carries out every single step in order, automatically." },
    { "term": "Mount", "explanation": "Mounting is telling Linux 'hey, there's an extra disk or folder sitting over here, please attach it to the main house so I can actually walk into it and use it.' Until you mount something, Linux basically doesn't know that storage exists or how to reach it at all." },
    { "term": "Fork (process)", "explanation": "When a program forks, it's basically cloning itself to create an identical twin that can help carry the workload, letting two copies of essentially the same program run and handle different tasks at the same time, instead of one program trying to juggle everything alone." }
