Android is a mobile operating system developed by Google, based on the Linux kernel and designed primarily for touchscreen mobile devices such as smartphones and tablets.

Android's user interface is mainly based on direct manipulation, using touch gestures that loosely correspond to real-world actions, such as swiping, tapping and pinching, to manipulate on-screen objects, along with a virtual keyboard for text input.

In addition to touchscreen devices, Google has further developed Android TV for televisions, Android Auto for cars, and Android Wear for wrist watches, each with a specialized user interface.

Variants of Android are also used on notebooks, game consoles, digital cameras, and other electronics.

An amplifier, electronic amplifier or (informally) amp is an electronic device that can increase the power of a signal (a time-varying voltage or current).

An amplifier functions by taking power from a power supply and controlling the output to match the input signal shape but with a larger amplitude.

In this sense, an amplifier modulates the output of the power supply based upon the properties of the input signal.

An amplifier is effectively the opposite of an attenuator: while an amplifier provides gain, an attenuator provides loss.

A computer network or data network is a telecommunications network which allows nodes to share resources.

In computer networks, networked computing devices exchange data with each other using a data link.

The connections between nodes are established using either cable media or wireless media.

The best-known computer network is the Internet.

A gadget is a small tool such as a machine that has a particular function, but is often thought of as a novelty.

Gadgets are sometimes referred to as gizmos.

Gizmos in particular are a bit different from gadgets.

Gadgets in particular are small tools powered by electronic principles (a circuit board).

Control theory is an interdisciplinary branch of engineering and mathematics that deals with the behavior of dynamical systems with inputs, and how their behavior is modified by feedback.

The usual objective of control theory is to control a system, often called the plant, so its output follows a desired control signal, called the reference, which may be a fixed or changing value.

To do this a controller is designed, which monitors the output and compares it with the reference.

The difference between actual and desired output, called the error signal, is applied as feedback to the input of the system, to bring the actual output closer to the reference.

Some topics studied in control theory are stability (whether the output will converge to the reference value or oscillate about it), controllability and observability.
