Science is the study of the natural world through observation and experimentation. The scientific method is used to test hypotheses and find solutions to problems. Electronics is the branch of science that deals with the study of electrical circuits and devices. It includes the design, fabrication, testing, and applications of electronic devices and systems.
The term “electronics” was first used in 1883 by French physicist Alexandre-Edmond Becquerel (1820–1891). He used it to describe the study of electricity in which currents are caused by electrons flowing through a conductor. The word “electronics” comes from the Greek word for amber, ēlektron (ἠλέκτρον). Amber was used in early electrical experiments because it could be electrically charged when rubbed with a piece of fur.
Today, electronics is an important part of our daily lives. It is used in communications, transportation, entertainment, manufacturing, and many other areas. Electronic devices such as computers, cell phones, and televisions use semiconductor materials such as silicon to create integrated circuits (ICs). These ICs are responsible for performing millions of calculations per second in modern computers. Most electronic devices today use digital technology instead of analog technology because digital technology is more reliable and can process data faster than analog technology.
Some common examples of electronic devices are:
• Computers and computer peripherals such as printers and scanners
• Cell phones and other portable communication devices
• Audio equipment such as radios, stereos, and MP3 players
• Television sets and video equipment
• Digital cameras
