Computer problem

As we Silver Surfers know, sometimes we have trouble with our computers.    Yesterday, I had a problem, so I called Georgie , the 11 year old next door, whose bedroom looks like  Mission Control, and asked him to come over.    Georgie clicked a couple of buttons and solved the problem.    As he was walking away, I called after him, 'So, what was wrong?    He replied, 'It was an ID ten T error.'    I didn't want to appear stupid, but nonetheless inquired, 'An, ID ten T error? What's that? In case I need to fix it again.'    Georgie  grinned ..'Haven't you ever heard of an ID ten T error before?    'No,' I replied.    'Write it down,' he said, 'and I think you'll figure it out.'    So I wrote down:    ID10T
