IT 10-Second Lesson | Understanding the QR Code | Funifytools

 

The QR code, created in 1994 by Masahiro Hara at Denso Wave, was designed to track car parts faster than barcodes.

It encodes information in black and white dots, where black = 1 and white = 0, forming a binary pattern readable by computers.

The finder patterns in three corners let scanners read the code from any direction, even if partially damaged.

QR codes can store various data — URLs, Wi-Fi info, contacts, maps, and payments — in a small image.

Today, they serve as a bridge between the physical and digital worlds, offering fast, contactless access to information.

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.
