Compressed Files (ZIP, RAR, 7Z): What They Are and Why They Matter | Funifytools

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).

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.
