Stages of ICT Development lima yan
-1st phase (until the second half of the nineteenth century)
-2nd setage(since the end of the XIX century)
-3rd stgae(40-60 - IES of XX century)
-4th stages(from the beginning of the 70s)
-5th stages(since the mid-80s)
“manual” information technology, tools which were: a pen, inkwell, book. Communication impl-Lis hand the conduit through the mail letters, packages, dispatches
