| What is electronic? Electronic systems
are used to perform a wide variety of tasks. The main uses of electronic today
include controlling and processing of data and conversion to electric power.
Electronic components are parts of electronic building block packaged inside.
All they are connected carefully by soldering to a circuit board. Some of the
active components are called ‘devices’,
too. We used electrical energy in telegraph and telephone lines, and in radio
transmissions before. |
