The Raspberry Pi is a low-cost credit-card sized computer, created by Eben Upton. It's a mini computer for educational purposes. To see all Raspberry Pi models, you can refer to https://www.raspberrypi.org/products/. Raspberry Pi 3 Model B and Raspberry Pi Zero are described here:

• Raspberry Pi 3 Model B: This is the third-generation Raspberry Pi. This board consists of a Quad-Core 64-bit CPU, Wi-Fi, and Bluetooth. It's recommended for your IoT solution:

• Raspberry Pi Zero: This is a small computer, half the size of model A+. It runs with a single-core CPU and no network module, but it provides micro HDMI to be connected to a monitor. Since there is no network module in Raspberry Pi Zero, you can extend it by adding a module; for instance, Ethernet USB or Wi-Fi USB to connect to a network. You can see a form of Raspberry Pi Zero in the following image:
