this is erm my version
"Activity 18
A computer is a machine for manipulating data according to a list of instructions. Computers take various physical forms. Early electronic computers were the size of a large room, consuming as much power as several hundred personal computers. Today computers can be made small enough to fit into a wrist watch and be powered from a watch battery. Society has come to recognise personal computers and their portable equivalent, the laptop computer, as icons of the information age; they are what most people think as a computer. "
it looks pretty good, spelling and grammar wise?
