Raspberry Pi also called RPI in short, is a series of small computers (microprocessor) developed in the United Kingdom by the Raspberry Pi Foundation. Raspberry Pi was actually made to give the basic idea of computer science to school children but it became so popular that more than 5 million copies were sold by Feb 2015 making it the best-selling British computer. Raspberry Pi has all of those features of the real computer in the size of a small chip, for example, it has processors, GPU, RAM, Broadcom system (SoC), 3.5mm jack audio output, HDMI video output, 1 to 4 USB ports, ethernet port etc. The actual specs vary from model to model. Raspberry is programmed by python.

The difference between Raspberry Pi Zero(2015), Raspberry Pi Zero W(2017) and Raspberry Pi Zero WH(2018) is that
Raspberry Pi zero W has all the features of Raspberry Pi Zero except these
* Bluetooth 4.1
* Bluetooth Low Energy
* 802.11 b/g/n Wireless LAN
Raspberry Pi zero WH has soldered GPIO pins that is the only difference between the Raspberry Pi Zero W.
