Operating Systems for Mobiles and Tablets

Mobile devices and tablets have become essential in personal and business environments. These devices rely on operating systems (OS) specifically designed to handle portable hardware, touch interfaces, power management, and mobile connectivity. A mobile OS manages device resources, runs applications, supports wireless communication, and ensures security while providing a user-friendly interface for interaction.

Unlike desktop and laptop OS, mobile and tablet operating systems are optimized for touchscreens, limited memory, battery efficiency, and wireless communication. They provide platforms for apps that enable business productivity, social connectivity, multimedia, and cloud computing.

The most widely used mobile and tablet operating systems are Android OS, Apple iOS, Windows Mobile/Windows Phone, and other emerging OS like HarmonyOS and KaiOS. Each has unique characteristics, features, and business applications.
