Magnetic tape was first used in UNIVAC 1 as a way of storing information
-
This was a new way of storing memory
-
This was the invention of the printer so files could be made physical from the computer.
-
Jack created the first integrated circuit. The invention of the integrated circuit led to the invention of the modern computer "chip" which has the power of million of transistors. This marked the beginning of the "third generation" of computers.
-
The invention of the mouse changed the way people were able to interact with computers.
-
This allowed personal computers to be connected to peripheral devices.
-
This created a new way of memory which is still used today.
