Can I run multiple OS on Raspberry Pi?

Raspberry Pi operates in the open source ecosystem, It can run a variety of Linux distributions on the go, directly from an SD Card.

Also, you can install multiple operating systems on different SD cards and use them for various purposes. As an example, you can have a Ubuntu OS on a memory card that is specifically set up for excellent graphical user interface, Arch Linux for being custom configurable, Fedora for productivity purposes, a Kali Linux for security & Penetration testing purposes, and a RaspbianOS for NAS or Network Attached Storage Server.

To access different Operating systems, you need to simply switch among the SD Cards to use Ubuntu, Raspbian, Arch, Fedora, Kali Linux, or any other Linux distributions & power up the Single board computer to run the Operating system without any additional hassles.

What can you do with Raspberry Pi?

With the same tasks that your computer can execute, a Raspberry Pi holds the amount of potential even after being a Credit Card sized Single Board Computer, with less computational power.

There are numerous types of projects that can be done with Raspberry Pi even if you’re a beginner. You name it, starting from Computer Vision, Robot controller, Machine Learning, Penetration testing, Cloud server setup, Network Attached Storage, Home automation, voice-controlled assistant, controllers, Smart TV, and a lot of innovative ones to try.

You can connect a Display monitor, keyboard, and Mouse and start using it like a regular computer. Even less memory intensive & lightweight games are playable on the Raspberry Pi.

By being creative, you yourself can discover thousands of projects that might come in handy in your daily life.
