Bots are robots which have no physical presence i.e. the exist purely on the internet. At its simplest a bot could be an algorithm which works autonomously on the web performing a desired function such as fetching data from one place an bringing it to another. At their most complex, the are near fully autonomous and can drive cars or fly planes.
As of yet, although rampant in cyberspace, (it is estimated that 64% of internet traffic are bots) they have not been given legal status to operate independently in the physical world.
