Technical English

In technical contexts, "technical" refers to the specialized knowledge, terminology, processes, and practices associated with a particular field or subject. Technical contexts often involve the use of specific jargon, methodologies, tools, and standards that are understood and used by experts in the field. These contexts can vary widely depending on the domain, such as technology, engineering, science, medicine, or any other specialized area. In essence, technical contexts involve the application of specialized knowledge and skills to address specific problems or tasks within a particular field or discipline.

A transistor is a semiconductor device used to amplify or switch electrical signals and power. It is one of the basic building blocks of modern electronics. It is composed of semiconductor material, usually with at least three terminals for connection to an electronic circuit. A voltage or current applied to one pair of the transistor's terminals controls the current through another pair of terminals. Because the controlled (output) power can be higher than the controlling (input) power, a transistor can amplify a signal. Some transistors are packaged individually, but many more in miniature form are found embedded in integrated circuits. Because transistors are the key active components in practically all modern electronics, many people consider them one of the 20th century's greatest invention.
