Elektronika inggih punika ngèlmu ingkang nyinau piranti listrik arus lemah ingkang dipun-ginakaken kanthi cara ngontrol aliran elektron utawi partikel ingkang wonten momotan listrik salebeting satunggal piranti kados komputer, piranti elektronik, termokopel, semikonduktor, lan sapanunggalanipun. Ilmu ingkang nyinau piranti-piranti kados punika minangka cawang saking ngèlmu fisika, sawatawis wujud desain lan pandamelan sirkuit elektronikipun inggih punika péranganing teknik elektro, teknik komputer, lan ngèlmu/teknik elektronika lan instrumentasi.

Piranti-piranti ingkang ngginakaken dhasar kerja elektronika punika dipunsebat minangka piranti elektronik (electronic devices). Tuladha piranti elektronik punika: Tabung Sinar Katode (Cathode Ray Tube, CRT), radio, TV, perekam kaset, perekam kaset video (VCR), perekam VCD, perekam DVD, kodhak video, kodhak digital, komputer pribadi desk-top, komputer Laptop, PDA (komputer saku), robot, smart card, lan sanès-sanèsipun.
