The beginnings
Taking the first electronic computer ENIAC in 1943 as a starting point. These computers had nothing that we would recognize as an interface. Today—instructions and data were f directly into memory locations at the start of execution via punch cards. And read from the processor registers, output directly in a binary dump. Onto punch cards or tapes, which had to be translat into something readable using separate mechanical devices.
Teletypes and terminals
The first advance was in an obvious direction. But it made both the use and the exploitation of the results much easier: the text interface. I am not talking about a screen yet, but about the adaptation of the teletype, a hybrid keyboard and printer, which began its existence as a more agile and reliable replacement.
For Morse code for long-distance communication
The teletype canada phone number library allow much more complex programs to be enter into memory, which l to the birth and popularization of a concept that seems very foreign to user interfaces: that of files. The first itors appear (obviously, much more spartan than we know today, and orient to line-by-line work), and as a direct consequence, programs could begin to present much greater complexity —leading the marketing relationship mix to the introduction of code libraries and the various abstractions and strategies to manage complexity.
The transition from teletype to screen is not
as simple as it might seem. Leaving aside the mere technical complexity (relative to the state of the art. At australia aatabase airectory the time) of creating independent and relatively. Low-cost devices capable of maintaining communication with the central computer, generating the image on the screen of the text they were receiving —which impli that they had an internal.
