Raspberry Pi- no, not the kind you eat, but the kind that is used in various eletronic devices such as IOT's, cameras and web servers. This commputer ranges from prices as low as $5 all the way up to $60. As for why the device is named as such, companies are allured towards naming themselves after fruits. The 'Pi' here stands for the programming language Python.
The idea was born in 2006 and the very first commercial unit was launched in 2012, since then there has been a linear growth in sales of the Raspberry Pi- over 30 million units sold. Don't be fooled by the size of this ingenious device, though small, it packs quite some punch. The Model 4 has a quad-core processor and up to 8GB RAM.
The CPU and the RAM of the raspberry are the core units for the computer to function, the WiFi Bluetooth Module enables the Raspberry to interact with the real world. An audio jack for connecting speakers and microphones is also provided; along with a CSI camera connector which enables us to build our own custom cameras. The GPIO- general purpose input output connector, to connect other electronic devices to the Raspberry Pi. We are also provided with an ethernet connection and 4 USB connections. Micro HDMI ports which enable us to connect to multiple monitors, and last but not least a USB C port to provide power to the computer.
The micro SD card can be said to contain all the code that makes the Raspberry Pi interact and function properlly with other hardware. We are provided with ability to install any OS we like, but most beginners go with the NOOBS installer which is a Linux based Raspberry Pi OS specifically tailored for starters.
The simplest use of a Raspberry Pi is as a deskstop computer- Along with the Pi itself, the micro SD card, and power supply, you'll need a HDMI cable and a display. Like a traditional computer, you'll also require a USB keyboard and mouse. After installing your preferred operating system, you'll find LibreOffice is pre-installed, along with the Chromium browser.
Now you can go take over all of existence armed with this knowledge, you are only limited by the boundaries that you make up but don't exist. There are limitless possibilities to use this hand sized computer, and you can make the best use of it.
