PARC's developments in information technology served for a long time as standards for much of the computing industry. Many advancements made at the center were not equaled or surpassed for two decades. Xerox PARC has been the inventor and incubator of many elements of modern computing, including:

*[[Ethernet]] as a local-area computer network<ref name=":1" />
*Fully formed [[object-oriented programming]] (OOP) (with [[Class-based programming|class-based]] inheritance, the most popular OOP model) in the [[Smalltalk]] [[programming language]] and [[integrated development environment]]
*[[Prototype-based programming]] (the second most popular inheritance model in OOP) in the [[Self (programming language)|Self]] language
*[[Model–view–controller]] software architecture
*[[AspectJ]], an aspect-oriented programming (AOP) extension for the [[Java (programming language)|Java]] language

===Alto===
{{Main|Xerox Alto}}
Most of these developments were included in the Alto, which added the [[computer mouse]].<ref name="fn_1"> Xerox PARC became the first research group to widely adopt the mouse invented by [[Douglas Engelbart]]'s [[Augmentation Research Center]] at the [[Stanford Research Institute]] (now [[SRI International]]) in [[Menlo Park, California]].</ref> These developments unified into a single model most aspects of now-standard personal computers use. The integration of Ethernet<ref name=EncycB/> into the computer prompted the development of the [[PARC Universal Packet]] architecture, which is structured much like the modern Internet's architecture.

===PARCTab===
The PARCTab is an experimental [[mobile computing]] device as an early experiment in [[ubiquitous computing]] (UbiComp).<ref>{{Cite web |title=PARCtab |work=Buxton Collection |url=https://www.microsoft.com/buxtoncollection/detail.aspx?id=51 |access-date=December 17, 2023 |publisher=Microsoft |url-status=live |archive-url=https://web.archive.org/web/20231217180913/https://www.microsoft.com/buxtoncollection/detail.aspx?id=51 |archive-date=December 17, 2023}}</ref> Its appearance resembles a [[personal digital assistant]] (PDA). Its functionality depends on the user's location, by receiving location-specific information via infrared sensors from gateway nodes installed in a particular location.<ref name=computerhistory>{{Cite web |title=Xerox PARCTab Prototype - PDA |url=https://www.computinghistory.org.uk/det/36785/Xerox-PARCTab-Prototype/ |access-date=December 17, 2023 |website=Computing History}}</ref>

It has a touch screen, stylus, and [[handwriting recognition]]. Xerox designed the similar and larger PARCPad. Both devices were developed around the same time as the [[Apple Newton]].<ref>{{Cite web |title=History of HCI |url=https://rauterberg.employee.id.tue.nl/presentations/HCI-history/ |access-date=December 17, 2023 |website=Homepage of Matthias Rauterberg }}</ref>
