Introduction :

The Raspberry Pi 4 Model B is the best performing single-board computer to date from the Raspberry Pi Foundation that has undergone a huge upgrade in comparison to all previous models.

The Pi 4 B is available in different memory versions (4GB) with true Gigabit Ethernet, USB-C power, USB 3.0, dual 4k display output and a quad-core CPU to rival the performance of an entry-level desktop PC. It’s a truly powerful and capable computer in a small, affordable package.
