At Key Stage 1 (ages 5 to 7) children are taught about algorithms, that they are a way of breaking tasks into a sequence of steps that can be reused to solve problems.
They will also be taught about the pervasiveness of software - about the different kinds of devices and appliances that rely on software.
Finally, they will be taught about privacy. I'm not sure of the content but I assume it'll be about managing information about themselves.
