the concepts of electronics

1. Digital electronics: is the sub-branch of electronics which deals with digital signails for processing and controlling various systems and sub-systems

2. Telecommunications: is a universal term that is used for a vast range of information-transmitting technologies such as mobile phones, land lines, VoIP and broadcast networks.

3. Analogy electronics is a branch of electronics that studies the variable factors (voltage, current, etc.) in a continuous way in time and can be taken (at least theoretically) infinite values

4. An electric current is a flow of electric charge. In electric circuits this charge is often carried by moving electrons in a wire. It can also be carried by ions in an electrolyte, or by both ions and electrons such as in an ionised gas (plasma).

5. Voltage, also called electromotive force, is a quantitative expression of the potential difference in charge between two points in an electrical field.

6. A resistor is anything that electricity can not travel through easily. When electricity is forced through a resistor, often the energy in the electricity is changed into another form of energy, such as light or heat.
