what is pic

It is a micro controller and I thinks u must search for this just like want he said to you

PIC stands for Peripheral Interface Controller. That is a family of micro controllers produced by Microchip. There are lots of available PIC programmers here in the net. PIC programmer is a hardware with a corresponding software. The software is responsible for transferring the code(HEX file) from the computer to the PIC chip. The chip serves as the interface between the chip and the computer. Basically you will be creating your programs on the computer and after compilation, you will be transferring the compiled output to the chip.

I have absolutely no idea.
