Raspberry Pi is a small single board computer. It’s a tiny credit card sized devices with so many uses and that’s used for all sorts of cool projects. Raspberry pi doesn’t seem very impressive. Especially when you get the spec sheet you get a Quadcore arm CPU that doesn’t support as the same instructions as a desktop or laptop. You can use the pi as a general purpose pc for web surfing and YouTube.
A few years back, Broadcom a company that manufactures Smartphone chipset joins hand with university of Cambridge in UK and together with the co-found Raspberry Pi foundation. A charitable organization dedicated for educational research. Initially, it was design for kids to learn programming and for the citizens for third well country. To have access to fully functional computer.
Later, when the gigue’s find out above this Raspberry pi they established doing all sort of cool projects with it and on the first day of sell more than hundred thousand units of pi were sold and apparently more than 5 million unit has been sold worldwide. Over the years, there has been several models introduced like B+ and the latest Raspberry pi 2 and like everything else it only gets better with each of date. For instance, RAM has been increased from 256MB to 1giga and similarly, CPU has been jumped from 700mghz of single core to 900mghz Quadcore. It’s giving a decent computing power to this latest version of Raspberry Pi.
Not only the Raspberry pi there are other competitors as well like banana pi, orange pi and beagle bones. Each one of them has the weakness and strength nothing beats pi on documentation and online resources. People just love pi and that makes it perfect for beginners.
How does it work
To start with it has a built-in RAM and CPU in this Broadcom chipset. The second small chip around here is controlling the USB and Ethernet interface. This brings us to this four USB port here. Which you can use to connect your mouse, keyboard or even a pen drive.
If you are connecting an external hard drive make sure you use a powered USB as the power supply from this pi will not be enough. Next, we have an Ethernet jack which you can use to connect your Pi to the internet. If you want a WI-FI on that you have it but you still need an extra wireless adopter for it. For power supply, Raspberry use a micro USB charger. And you want to connect with a monitor there’s an HDMI port.
