Raspberry Pi

The Raspberry Pi (or RasPi) is a $35 single-board computer developed in the UK by the Raspberry Pi Foundation which aims to ‘promote the study of computer science and related topics, especially at school level, and to put the fun back into learning computing.’ The design is based around a Broadcom BCM2835 system on a chip (SoC), which includes a 700 MHz ARM CPU, VideoCore IV GPU, and 256 Megabytes of RAM. The design does not include a built-in hard disk or solid-state drive, instead relying on an SD card for booting and long-term storage.

The foundation has released one model (Model B) initially, and a second model (Model A) will be released sometime later. Model A will have one USB port and no Ethernet controller, and will cost $25, while Model B contains two USB ports and a 10/100 Ethernet controller and costs $35. Though the Model A doesn’t have an RJ45 Ethernet port, it can connect to a network by using a user-supplied USB Ethernet or Wi-Fi adapter. As is typical of modern computers, generic USB keyboards and mice are compatible with the Raspberry Pi. The system will use a Linux kernel-based operating systems.
