Types Of Computer
Overview
A computer no longer means a beige box under a desk. It might be a powerful desktop, a slim laptop, a smartphone in your pocket, a tablet on the sofa or a phablet somewhere in between. Each design makes a different bargain between power, price and portability, and choosing the right one for a job is a genuinely useful skill.
In this lesson you will learn the characteristics and uses of desktop computers and of the four kinds of mobile computer, and you will be able to weigh their advantages and disadvantages. By the end you will be able to recommend the best type of computer for a given person or task and justify your choice, which is exactly what ICT exam questions ask you to do.
