What are the pre mechanical period?

What are the pre mechanical period?

The pre-mechanical age is the age in which there were no kinds of computer systems. This was a very long time ago, estimated to be around 3000BC. This date is very much an estimate as it is difficult to gather evidence about what systems were in use so long ago – it could have been nearer to 500BC.
