"Breadboard" or more precisely Proto-Boards are a type of solderless electronic circuit building. You can build an electronic circuit on a breadboard without any soldering! Best of all it is reusable.
A Breadboard is utilized to ensure a circuit works accurately without soldering in the components since Breadboard has sockets you can push components into, and take them out of afterward.
Some people confuse between proto-board and breadboard, however, the two are breadboards, one without and one with the "bus" strips.
How It Works
Basically, a bread board is an array of conductive metal clips encased in a box made of white ABS plastic, where each clip is insulated with other clips. There are a number of holes on the plastic box, arranged in a particular fashion. A typical bread board layout consists of two sorts of a region also called strips. Bus strips and socket strips. Bus strips are usually used to provide power supply to the circuit. It comprises of two columns, one for power voltage and other for ground.
Socket strips are used to hold most of the components in a circuit. Generally, it consists of two sections each with 5 rows and 64 columns. Every column is electrically connected from inside.
Finally, breadboards allow us to make our initial prototype much easier and much cleaner.
