smarttelefon

A smarttelefon, or smartphone, is a mobile device that combines a telephone with a powerful computer. It typically runs a mobile operating system, supports downloadable applications, and provides persistent internet connectivity via cellular networks or Wi-Fi. Smartphones enable a wide range of tasks including communication, navigation, media consumption, photography, and productivity, often at the same time.

Core hardware typically includes a touchscreen interface, a multi-core processor, RAM in the gigabytes, internal storage, camera modules, and wireless radios (cellular, Wi-Fi, Bluetooth, NFC). Modern devices feature sensors such as accelerometers, gyroscopes, ambient light sensors, GPS, and fingerprint or face authentication. Battery life varies with use and capacity; devices are frequently updated with new hardware through annual or biennial refresh cycles.

Smartphones emerged in the late 1990s and early 2000s and gained mass popularity with the introduction of the iPhone in 2007 and the subsequent growth of Android. The major software platforms are iOS and Android, with other systems such as KaiOS serving specific markets. Apps, distributed through official stores, extend functionality for messaging, gaming, productivity, and services.

Impact: smartphones have transformed communication, work, and access to information, influencing commerce, education, and culture. They raise considerations about privacy, security, and digital well-being, and remain subject to rapid hardware and software evolution as networks and apps grow more capable.
