What's peripheral? In the case of the use of technology in schools around the world, it is becoming increasingly hard to tell.
In many developing countries, for better and/or for worse, the traditional way to approach large-scale ICT procurements is to divide such undertakings into four primary components: hardware; software (which often includes 'e-content'); connectivity; and peripherals. (Thankfully, 'training' is showing up as a fifth component more and more ... although in most instances we are still only talking about 'technical training').
The category of 'peripherals', a catch-all category where one typically finds things like like printers and projectors, is often treated as the poor cousin of the other, 'flashier' components. But this may be changing.
