C# (pronounced "C sharp") was developed by Anders Hejlsberg at Microsoft as the primary language for programming on the .NET Framework, which is used to build a wide range of applications for Windows.

HTTP is the foundation of data communication for the World Wide Web. It is an application protocol for distributed, collaborative, hypermedia information systems.

The UNIVAC I, developed by J. Presper Eckert and John Mauchly, was the first American commercial computer and a classic example of a first-generation computer that used vacuum tubes.

The first laser printer was invented at Xerox PARC (Palo Alto Research Center) in the early 1970s. Specifically, Gary Starkweather, a researcher at Xerox PARC, developed this groundbreaking technology by modifying an existing Xerox copier in 1971. This invention was a crucial component of the visionary Xerox Alto personal computer system, demonstrating advanced printing capabilities, and ultimately revolutionized office and personal computing document output.

The term 'surfing the Internet' was popularized by librarian Jean Armour Polly. She used this vivid metaphor in an article titled 'Surfing the INTERNET: An Introduction' published in the Wilson Library Bulletin in June 1992. The phrase quickly resonated with the public, encapsulating the experience of exploring and navigating the vast and fluid information landscape of the nascent internet. While Tim Berners-Lee, Vint Cerf, and Marc Andreessen were pivotal figures in the development of the internet and web technologies, Polly was instrumental in coining and popularizing the accessible terminology.

Released in 1981, the Osborne 1 was the first commercially successful portable computer. It came bundled with a suite of popular software, which was a key part of its value proposition.

Robert Metcalfe invented Ethernet in 1973 while working at Xerox PARC. It has since become the most widely installed local area network (LAN) technology.

BASIC was designed in 1964 by John Kemeny and Thomas Kurtz at Dartmouth College. It was intended to be a simple, easy-to-learn language for students who were not from technical backgrounds.

The IBM System/360, launched in 1964, was a pivotal development in computer history due to its 'compatible family' concept. Prior to this, software was typically tied to a specific machine model. The System/360 introduced a revolutionary design where a range of computers, from small business machines to large-scale mainframes, could all execute the same operating systems and applications. This 'upward compatibility' meant businesses could upgrade their hardware without rewriting their entire software base, significantly reducing costs and increasing flexibility. This architecture set a new standard for computer design and profoundly influenced future generations of computers, including the architecture of modern PCs.

The UNIVAC I (Universal Automatic Computer I) was the first American commercial computer. Its televised prediction of an Eisenhower victory with only a tiny fraction of votes counted brought it and electronic computers to public attention.
