A PCB is a printed circuit board, also known as a printed wiring board. It is used in electronics to build electronic devices. A PCB serves two purposes in the construction of an electronic device; it is a place to mount the components and it provides the means of electrical connection between the components.
A PCB starts out as a thin, non-conducting sheet of material. The most common material used is a glass fiber epoxy laminate material. A thin layer of copper is then chemically deposited on each side of this material.
The next step is to "print" the connection diagram onto the PCB. The connection diagram is the wiring required to connect the components. In the very early days of electronics, these connections were in fact done with wires. This is the reason PCBs are also sometimes referred to as printed wiring boards. The "printing" is usually done by photographically transferring the image to the board. This image is "printed" with an acid resistant material.
