The Raspberry pi is a mini computer which is designed in a single board with all the essential components required for running an operating system. The Raspberry pi is a device which uses the Broadcom controller chip which is a SoC (System on Chip). This SoC has the powerful ARM11 processor which runs on 700 MHz at its core. This minicomputer comes without a display unit, but it can be used with HDTV display or normal NTSC or PAL standard TV screen. It has an Ethernet port which allows it to be connected to a network. Operating systems from Mac, Windows and Linux can be loaded in the Raspberry pi. The capability of this inexpensive board to load operating systems from Linux and accessibility of the board through a LAN network makes it a perfect choice for tiny dedicated web servers.
In this particular project Ubuntu is installed on Raspberry pi board and is loaded on the Raspberry pi board and is connected to a router using a cross-over LAN cable. Hence the only additional hardware required with the Raspberry pi for this project is a LAN cable only.
