What Is Android? Linux Roots, Google Ecosystem, Pros & Cons

Android, built on the Linux kernel, began in 2003 and—after Google’s 2005 acquisition—became the world’s leading mobile OS.

Its open-source model let countless manufacturers adopt and customize it, driving ~70% global smartphone share.

Tight integration with Google services (Play Store, Gmail, Drive, YouTube) fuels a massive app and device ecosystem.

Key challenges include fragmentation and delayed updates across brands and models.

Android now spans phones, TVs, cars, and wearables, and is rapidly evolving with AI, AR, and IoT.

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.
