Raspberry Pi for ICT

21 Dec Raspberry Pi for ICT

ICT are very excited about their new Rasberry Pi. The Raspberry Pi is simply a printed circuit board with a couple of input ports, some output ports, and some RAM. It is approximately the size of a credit card.

It is extremely powerful for its size and is capable of running web servers, small electronic gadgets as well as normal computing tasks such as word processing, spreadsheets, internet browsing and email. Best of all the Raspberry Pi costs £35, a fraction of the cost of a basic pc. It is also great for learning about basic computer programming.

The Raspberry Pi has no built-in storage to run an operating system or save the project files. For this you need an SD card – the same used in digtal cameras.

The Raspberry Pi supports most USB keyboards and mice. You can also use a wireless keyboard and mouse if you’re low on USB ports, but be aware that power consumption may stop the Pi starting up.

The Raspberry Pi takes its power from a standard micro-USB port. If you have a mobile phone charging cable you can probably use that — just check the voltages.  The more peripherals you plug in to the Raspberry Pi — for example, DVD drives, external HDDs, and WiFi dongles — the more power the Pi will need.

The Raspberry Pi has two display output options — HDMI, and composite video. In my experience HDMI gives the most flexibility and best quality image but it depends on what ports the monitor has available. The Pi is designed so that you can plug it into a standard television with an HDMI port free.
