[Gadgets] Computer parts and their shapes [electronics]

[Mihawk.]

A field concerned with the study of electric charges (moving electrons) from non-metallic conductors (often called semiconductors), while electricity refers to the flow of electric charges through metallic conductors. For example, the flow of electric charges through silicon, which is a non-metal, falls under the "electronics" framework, while the flow of electric charges through copper, which is a metal, falls under the framework of "electricity". This, and the distinction between these two terms for the first time began around 1906 when "Le de Forest" invented the triode.Until 1950, the field of electronics was called "wireless technologies"; This is because it was primarily used in the designs and theories of transmitters, radio receivers, and vacuum tubes. Moreover, the study of semiconductors and their technology is a branch of physics, while the design and construction of electronic circuits to solve practical problems is a branch of electronics engineering. This article focuses on the engineering aspects of electronics.

In modern devices, transistors are used instead of vacuum tubes. For example, a mobile phone works with small and light transistors, and vacuum tubes are not suitable for it, as they are large in size, and a mobile phone works with an accumulator with a small voltage of less than 10 volts, while the vacuum tube needs an electrical source with a voltage of 150 volts at least. Without transistors, man would not have been able to go to the moon.
