Answer:
First, let’s understand GUI History:
The Graphical User Interface (GUI) is an interface that allows users to interact with computers using graphical elements such as windows, icons, and buttons instead of text commands.
Given Options: Step by Step Answering:
a) Apple Computer
- Apple popularized the GUI with the launch of its Lisa computer in 1983, followed by the Macintosh in 1984. However, Apple did not invent the GUI; it refined and commercialized the technology.
b) Microsoft
- Microsoft introduced its first GUI-based operating system, Windows 1.0, in 1985. Similar to Apple, Microsoft did not create the GUI but rather developed its own version after it became popular.
c) Xerox
- The Xerox Palo Alto Research Center (PARC) was where the GUI was first developed in the mid-1970s. The Xerox Alto was the first computer to feature a graphical user interface, though it was never commercially sold. This system influenced later GUI designs by Apple and others.
d) IBM
- IBM was influential in early computing and produced the IBM PC in the early 1980s, but it did not pioneer the GUI. IBM worked more on text-based interfaces and later adopted GUI technologies.
Final Answer:
Based on the above analysis, the correct answer is:
C) Xerox
The pioneering work for the graphical user interface was done by Xerox PARC in the mid-1970s.
