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

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.
