Installing software unpacks many support files, but the program actually runs via an executable (.exe) that instructs the OS what to load. The .exe is the “ignition key,” coordinating DLLs, configs, and other resources to start the app. Desktop icons are shortcuts pointing to the real .exe; deleting a shortcut doesn’t remove the program, uninstalling does. Executables are produced by compiling source code into machine code, turning developer logic into a runnable file. Knowing the roles of executables, support files, and shortcuts clarifies how programs launch and sets the stage for learning to code.

In Windows, storage devices (HDD/SSD) appear as lettered drives that act like big drawers for your data. The C: drive is the system’s heart, typically housing Windows and most installed apps. A D: drive often serves as secondary storage (separate partition or disk) for personal files, easing reinstalls. Letters start at C: because A: and B: were historically floppy drives; USB letters can be reassigned—never change C:. Drives can also be virtual or cloud-backed (ISO mounts, OneDrive), so a “drive” is an addressing concept, not just hardware.

Compressed files (e.g., .zip, .rar, .7z) shrink data and bundle many items into one, easing storage and transfer. File size is measured in bytes (KB/MB/GB/TB); large or numerous files benefit most from compression. Compression is lossless: extracting restores the exact originals for safe sharing and organization. Windows handles basic ZIPs natively; advanced needs are covered by tools like 7-Zip, WinRAR, and ALZip. Common formats include .zip (high compatibility), .rar (strong features), .7z (efficient/open-source), and .tar.gz (Linux). photo by cottonbro studio on pixels 7-Zip program WinRAR program ALZip program You can view the original blog post in Korean and English at the links below: [  View in Korean  ] | [ View in English ]

Reports suggest Dunamu (Upbit) could become a Naver Financial subsidiary via a potential share swap. A tie-up could merge Naver Pay’s real-world payments with Upbit’s crypto rails, forming a daily-use digital-asset ecosystem. Likely impacts: stronger regulatory credibility, broader stablecoin usage (e.g., via Naver Pay points), and short-term sentiment boosts. Naver Pay could evolve into a “super app” with stablecoin points, an expanded wallet (crypto/NFTs), and integrated finance features. Risks persist: shifting regulations, competition (Kakao, Toss), and crypto volatility/security—big opportunity, big challenges. maybe...

File extensions are the suffixes after a dot that identify a file’s type and which app can open it. Examples include .docx (Word), .jpg (image), .mp3 (audio), .mp4 (video), .pdf (document), and .exe (program). Operating systems link extensions to default applications, and you can change these associations as needed. Enabling “show file name extensions” in Windows makes file management clearer and prevents confusion. Watching extensions improves security by exposing disguised executables, helping you work more safely and efficiently.  You can view the original blog post in Korean and English at the links below: [ View in Korean ] | [ View in English ]

A file is a container for data—documents, photos, music, videos, or even programs—you open, save, move, and share. Directories (folders) organize files and can contain other directories, creating a hierarchical tree from a root (e.g., C:\ in Windows). This structure makes finding and managing information easier, like grouping photos into “Travel,” “Family,” and “School.” The operating system manages names, locations, sizes, and timestamps through a file system (NTFS on Windows, APFS on macOS, ext4 on Linux). Grasping files (units of data) and directories (their containers) is foundational for deeper computing topics—next up: file extensions. photo by Tima Miroshnichenko on pixels You can view the original blog post in Korean and English at the links below: [  View in Korean  ] | [ View in English ]

 Installing software isn’t just copying files—it registers the app with the OS so it can run properly. Installers copy components, create settings/data folders, add Start/desktop entries, and set file associations. Even the operating system is “installed” first to provide the bootable foundation for all other apps. Phone app installs (App Store/Play) automate the same steps: download → register → icon → launch. Prompts for license, install path, shortcuts, and associations simply tell the OS how to integrate the app. You can view the original blog post in Korean and English at the links below: [  View in Korean  ] | [ View in English ]

Windows includes ready-to-use core apps (Notepad, Paint, Calculator, File Explorer, Media/Photos, Snipping Tool, Mail/Calendar, Clock/Recorder) plus Terminal/PowerShell, Store, Widgets, and Teams. All follow the same pattern: workspace + menus; your input produces an immediate, visible result—great for beginners. Notepad/Calculator/Photos/Paint cover quick notes, math, and basic image tweaks; File Explorer handles organizing, searching, and managing files. Snipping Tool streamlines screenshots; Mail/Calendar centralize communication and schedules; command tools enable automation and bulk tasks. Built-in apps are intentionally simple “starting line” tools; add pro software (Office, Photoshop, Premiere, etc.) as your needs grow.

Apps are the visible tools we use, while the OS works behind the scenes; in practice, using a computer means using applications. Most apps share one skeleton: a main workspace plus menus; you issue a command and see the result immediately. Menus typically sit at the top/side, and right-click context menus surface relevant actions quickly. Common patterns: File (open/save/print), Edit (copy/paste/undo), View (zoom/toolbars) plus app-specific menus—and a Help section. To learn any new app fast: scan the menus, try simple input → result steps, and iterate—this pattern removes fear and speeds mastery.

Analog signals are continuous and natural but easily degraded by noise or distortion. Digital signals convert real-world data into numbers, ensuring stability and easy duplication. Analog offers infinite precision, while digital trades subtlety for reliability and error correction. Everyday tech blends both — analog sensing, digital storage, and analog playback for humans. The key is choosing the right form: analog for nuance, digital for precision and scalability.   What is Analog? What is Digital?

Android, built on the Linux kernel, began in 2003 and—after Google’s 2005 acquisition—became the world’s leading mobile OS. Its open-source model let countless manufacturers adopt and customize it, driving ~70% global smartphone share. Tight integration with Google services (Play Store, Gmail, Drive, YouTube) fuels a massive app and device ecosystem. Key challenges include fragmentation and delayed updates across brands and models. Android now spans phones, TVs, cars, and wearables, and is rapidly evolving with AI, AR, and IoT.

Linux (1991, Linus Torvalds) is a free, open-source OS known for stability and security, powering servers, supercomputers, and Android. It grew from command-line roots into user-friendly distros (Ubuntu, Fedora, Debian, Mint) via a global open-source community. Strengths: cost, openness, reliability; downside: weaker compatibility for some commercial apps/games vs. Windows. Essential for developers/IT (programming, DevOps, security, AI); over 90% of supercomputers and many research orgs use Linux. Windows excels for everyday convenience, while Linux underpins cloud/AI/IoT—complementary choices depending on your goals. The Linux Mascot : Tux “Really, I’m not out to destroy Microsoft. That will just be a completely unintentional side effect.”  -  Linus Torvalds   You can view the original blog post in Korean and English at the links below: [  View in Korean  ] | [ View in English ]

Windows popularized personal computing, evolving from MS-DOS/Windows 1.0 through 3.1/95/XP/7/10 to today’s Windows 11. Milestones: Start menu/taskbar era (95/98), rock-solid XP, course corrections after Vista/8, and modern, cloud-integrated, security-focused Windows 11. Biggest strengths are ecosystem and compatibility—DirectX for gaming, vast software/hardware support—powering both home and work. Trade-offs include security targeting and occasional driver conflicts; licensing comes as OEM, Retail (FPP), and Volume options. The future ties Windows to cloud, AI, and virtualization (via Azure), keeping it central to consumer and enterprise computing.

The OS is the invisible manager that bridges hardware and software, allocating CPU, memory, storage, and I/O. It provides CLI/GUI interfaces, abstracts device details, and loads/runs programs end to end. Multitasking is achieved via time-slicing, letting multiple apps appear to run simultaneously. 32-bit (~4GB RAM limit) vs 64-bit (vast memory, better efficiency/security); modern systems are effectively 64-bit. OS history spans Unix → MS-DOS/Windows → Linux/open source → iOS/Android, and today virtualization lets multiple OSes run on one machine.
