Parts or Components in Electronics :
When i saw CadSoft
EAGLE Layout Editor i wanted to try drawing circuits with it, Some
circuits documented from my design note book are here with the editable
schematics.
Here are circuits made of Resistors, Capacitors and Inductors which are
passive components. Crystals, Thermistors, Varistors, Variable Passive
RLC are also Passive Parts.
Zeners, Diodes, NPN-PNP Transistors, FET, MOSFET,
SCR, Triacs are all discrete active devices. ICs and Hybrid Modules
are made of many discrete and passive components. In
the Integrated Circuits or ASICs, all parts even passives are derived
on the Silicon Wafer. In Hybrid
Modules the construction uses SMD or Tiny Chip components
interconnected in a
small ceramic PCB and Hermetically Sealed if needed.
Parts like Switches, Connectors, Relays and PCBs are ElectroMechanical
parts. Nuts, Bolts, Screws, Cabinets and enclosures are
Mechanical parts.
For a Systems Integrator or Control Panel Designer, the Timers,
Controllers, PLC which are Electronic Products become Components or
Modules along with Contacters, Current Transformers, AC-DC Drives etc.
Components have to be wired up on boards while designing or testing
circuit blocks or concepts. Some examples of these are shown below.

Bread Board -
This is a reusable gadget like a connector, works like an IC base, only
that the connectors in this are very long lasting. you can just plug in
the components and connect using thick pre-tinned single strand wire.
Big pins can ruin the sockets and power circuits. Levels > 200mA or
> 24V could be avoided on these boards.
General Purpose PCB -
This is a PCB that is available is some shops, they are known as
"General Purpose Prototyping Board". They have to be soldered and some
tracks cut with tool-knife. Power circuits also can be built with wire
reinforcements and RF circuits too if you plan the layout first on
paper.
SchmartBoard -
This is a new innovation SchmartBoard, see this link
for some ideas see Circuits
Specialists too.
