elektroonikaseadet

An elektroonikaseade, or electronic device, is a system that uses electric circuits to perform a specific function. These devices operate by manipulating electrical energy and the flow of electrons to process information, control other devices, or produce output. Common examples range from simple calculators and remote controls to complex computers, smartphones, and industrial machinery.

The fundamental components of most electronic devices include semiconductors, such as transistors and diodes, which act as switches or amplifiers for electrical signals. These are often combined with passive components like resistors, capacitors, and inductors to create integrated circuits. These circuits are the brains of the device, performing calculations, storing data, and managing operations.

Electronic devices are ubiquitous in modern life, powering everything from communication and entertainment to healthcare and transportation. Their development has been driven by advancements in miniaturization, processing power, and energy efficiency, leading to increasingly sophisticated and portable technologies. The design and manufacturing of these devices involve intricate processes, adhering to strict engineering principles and safety standards.
