User journeys describe at a high level of detail exactly what steps different users take to complete a specific task within a system, application, or website. This technique shows the current (as-is) user workflow, and reveals areas of improvement for the to-be workflow. When documented, this is often referred to as a User Journey Map. [1]
A human computer, with microscope and calculator, 1952. It was not until the mid-20th century that the word acquired its modern definition; according to the Oxford English Dictionary, the first known use of the word computer was in a different sense, in a 1613 book called The Yong Mans Gleanings by the English writer Richard Brathwait: "I haue [] read the truest computer of Times, and the best ...
After such a file is created, typical operation is to present it as a slide show using a portable computer, where the presentation file is stored on the computer or available from a network, and the computer's screen shows a "presenter view" with current slide, next slide, speaker's notes for the current slide, and other information.

The original GUI was developed on the Xerox Alto computer system at Xerox Palo Alto Research Center in the early 1970s and commercialized by many vendors throughout the 1980s and 1990s. Since the late 1990s, there have been three operating systems in widespread use on personal computers: Apple Inc.'s macOS, the open source Linux, and Microsoft ...

The first documented computer architecture was in the correspondence between Charles Babbage and Ada Lovelace, describing the analytical engine.While building the computer Z1 in 1936, Konrad Zuse described in two patent applications for his future projects that machine instructions could be stored in the same storage used for data, i.e., the stored-program concept.
Her notes on the analytical engine, written in the 1840s, are now recognized as the earliest examples of computer programming. [53] Lovelace saw potential in computers to go beyond numerical calculations, predicting that they might one day generate complex musical compositions or perform tasks like language processing.
