History of the GUI or Graphical User Interface

Modern computers, the use of which has made our lives faster and easier. I get the desired result by clicking. Initially the command line interface (CLI) / disk operating system (DOS, eg: MS-DOS) computer did not have this facility to click. There was work to be done by typing line after line of specific commands on the keyboard. And now the click-click-click computer we use is made possible by the graphical user interface.

The GUI was invented by Xerox-Palo Alto Research Center (Xerox-PARC), a renowned research (R&D) organization. In the early seventies, several researchers led by Alan Kay were able to discover the "GUI". Silicon Valley technologist Douglas Engelbart, on the other hand, invented the "mouse" and called it the "Father of GUI."

The "Xerox Alto" (in 1973) is a combination of GUI window, mouse or pointing device, QWERTY keyboard and CRT monitor, and is the first mini computer in the GUI operating system (similar to today's personal computer). The Xerox Star came in 1981 in its continuation. Despite its extreme success, Xerox did not go into commercial production of these devices.

Sensing success, the visionary technologist "Steve Jobs" came forward. Xerox bought Alto's GUI patent and gave birth to the famous "Apple Macintosh" in 1984, the first commercial personal computer. With a graphical user interface and mouse, Apple doesn't have to look back to gain popularity and success. Microsoft also began to walk the same path, realizing the power of the graphical user interface.

People can easily understand and remember by looking at pictures / videos or hearing words from reading letters. And with this realization, the CLI-based operating system has been removed and the icon + based operating system has become acceptable to computer users.
