What is Electronics ?

Under science, electronics or electronics is that area of ​​science and technology that studies the flow of charge (mainly electrons) through different types of mediums (vacuum, gas, metal, semiconductor, nano-structure, etc.) and devices based on them. is.

All electronic components can be divided in to two categories: 

1. Active devices

2. Passive devices

Active devices are such type of devices which are given the supply first of all for taking them in the working condition, afterward energy is generated by them, e.g. IC etc. 
Passive devices do not produce energy. They function as supporting devices, like capacitors, resistance etc. 
As a technology, it is the field of electrons that uses various electronic devices (resistors, capacitors, inductors, electron tubes, diodes, transistors, integrated circuits (IC), etc.) to produce the appropriate electrical circuit and the electrical signals through them are desired. Is related to manipulation.
This includes the study of various types of devices, improvement of them and creation of new devices etc. Historically, the field of electronics and electrical technology has been the same and both were not considered to be different from each other. But now, with the expansion of new devices, circuits and the functions they perform, electronics are beginning to be taught as a separate branch of electrical technology.
In this view, more electric-power related fields (power systems, electrical machinery, power electronics, etc.) are considered under electrical technology, while less electric power and electric signals are subject to changes (amplification, filtering, modulation, analysis). Field related to digital conversion etc.) is called electronics. 

Electronic Technology Parts

Based on circuits, electronic technology is mainly divided into two parts:

Analog electronics

Analog electronics In these circuits the electrical signals are continuous (analog) and even after processing them they remain constant. For example, the transistor-amplifier is an analog system. The development of operational amplifier and its availability as I-C led to a revolution in analog electronics. Digital or digital electronic.

Digital electronics

It consists of electrical signals numeric. Digital signals can be of many types, but binary digital signals are most commonly used. Zero / one, on / off, yes / no, low / high etc. are some examples of binary signals.
Digital electronic has become very important ever since integrated circuits have emerged and millions of electronic devices are being loaded into a small chip.
Modern personal computers (PCs) and cell phones, digital cameras, etc. are the product of digital electronics. Digital electronics has given a new dimension to signal-processing called digital signal processing (digital signal processing). Compared to analog signaling processing, it is very facilitative.
