Elektronika, in the context of computer science and technology, refers to the branch of engineering and technology that deals with the study and application of electronic circuits and devices. It encompasses the design, development, and implementation of systems that utilize the flow of electrons to perform various functions, including signal processing, computing, and communication.

In broader terms, elektronika involves the use of components such as semiconductors, diodes, transistors, integrated circuits (ICs), and microprocessors, which are fundamental to modern computing and electronic devices. This field is essential for creating hardware that underpins software applications, enabling devices from computers and smartphones to industrial machinery and consumer electronics to operate efficiently.

Moreover, elektronika plays a critical role in fields such as embedded systems, robotics, telecommunications, and automation. Understanding the principles of electronics is crucial for engineers and developers working in these areas to effectively design and troubleshoot electronic systems.
