Electronics has branches as follows:
1. Digital electronics
2. Analogue electronics
3. Microelectronics
4. Circuit design

An electronic component is any physical entity in an electronic system used to affect the electronsor their associated fields in a manner consistent with the intended function of the electronic system. Components are generally intended to be connected together,

Vacuum tubes (Thermionic valves) were among the earliest electronic components, They were almost solely responsible for the electronics revolution of the first half of the twentieth century, They allowed for vastly more complicated systems and gave us

 ...

Circuits and components can be divided into two groups: analog and digital. A particular device may consist of circuitry that has one or the other

 ...

Electronic noise is defined as unwanted disturbances superposed on a useful signal that tend to obscure its information content. Noise is not the

Mathematical methods are integral to the study of electronics. To become proficient in electronics it is also necessary to become proficient in the mathematics of circuit analysis.

 ...

Heat generated by electronic circuitry must be dissipated to prevent immediate failure and improve long term reliability. Heat dissipationis mostly achieved by passive conduction/convection.
