You must have seen a laptop, a desktop, or a smartphone in action. But do you know what a Raspberry Pi is? Well, today we are going to talk about this marvelous piece of technology which is making the lives of many people much easier.
What is Raspberry Pi?
Raspberry Pi is a 'system on a chip' based computer. It is very small in size compared to normal PCs. The size of Raspberry Pi might even be comparable to your smartphone. What is a system on a chip (SoC), you might ask? Well, SoC means that all of the systems of the PC are present on a single chip.
Raspberry Pi is an ARM-based computer, meaning only the ARM-based operating systems would work on it. Luckily, both Windows and Linux have their ARM-based versions, with the ARM-based Linux distros pretty much still in the cradle.
The first Raspberry Pi SoC was made for teaching programming. But pretty soon it became so much popular that it is now one of the go-to choices of tech enthusiasts who want a system at a low budget. It consists of a CPU with integrated graphics, USB, HDMI and Ethernet ports, RAM, etc. all packed on a single compact chip. A Raspberry Pi does not have storage built-in. It has the port for inserting an SD Card, which you can install your OS on.

Conclusion
Raspberry Pi is an excellent choice if you are looking for a cheap PC with decent performance. You can buy accessories for the Raspberry Pi too like a case for protection and ventilation, which can make your experience even better. Many cases have heat sinks built into them too. Remember that you have to get a monitor, keyboard, and mouse separately if you do not have one already!
