10-Second Lesson | How Passwords Are Actually Stored | Funifytools

 Passwords are never stored as plain text on a server — they are transformed before saving.

A hash function converts the password into an irreversible string, acting as a one-way encryption.

During login, the entered password is hashed again and compared with the stored hash value.

Even if hackers steal the database, they only see random-looking hash strings, not real passwords.

Hashing serves as a digital shield, protecting user information and ensuring privacy.

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.
