The computers we use in the computer labs are mostly Raspberry Pi 3 Model B+. It is a credit card-sized computer that can run a majority of applications that an average desktop computer can run, but using less than fifty times power and at a fifth of the cost. It is a highly effective solution to bridging the widening technological gap in developing countries' education systems.
The System on Chip (SoC) computer card is packed with features such as built-in wi-fi, Bluetooth, four USB ports, a microSD card slot, and a 1.4 GHz CPU backed by 1GB RAM. Its Linux based operating system is optimized to be used as a stand-alone computer or in a client-server mode. The Raspberry Pi OS and digital content are loaded into a microSD card and inserted directly into the computer for its operation. It can connect to internet through built-in Wi-Fi and lightweight Chrome browser. The OS comes with default softwares such as Libre Office and programming languages like Scratch, Java and Python. The latest version - Raspberry Pi 400 - is integrated into a keyboard and has quad core processors with up to 4 GB RAM running at 1.6GHz.
