Files and Directories: The Basics of How Computers Organize Data | Funifytools


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.

Understanding Computer Components: A Complete Look Inside Modern Systems | Funifytools

Image
Most computers follow the Von Neumann architecture: programs and data share memory; the CPU fetches and executes instructions sequentially. CPU is the brain for arithmetic/logic/control—often with NPUs—while the motherboard is the nervous system linking all parts via buses. RAM is fast, volatile short-term memory for active tasks; storage (SSD/HDD/NVMe) is long-term, persistent data. PSU supplies stable DC power; GPU accelerates graphics/video and many AI workloads; I/O devices let you interact; the case cools and protects. Together they form one system—same principles power phones like the iPhone, just in a tighter, integrated form.
