Which one of the following pairs of events and years is not correctly matched?
Introduction of the World Wide Web (www) : 1995
The question asks us to identify the pair of event and year that is not correctly matched. We need to examine each option to determine the historical accuracy of the given year for the specific technological or communication event.
Let's break down each option presented:
Based on the analysis, the pair that is not correctly matched is the "Introduction of the World Wide Web (www) : 1995". The World Wide Web was introduced several years before 1995.
Comparing the historical facts with the years provided in the options:
| Event | Year Given | Historical Accuracy | Correct Year/Period |
|---|---|---|---|
| Launch of the first communications satellite | 1962 | Generally Correct (Active satellite) | 1962 (Telstar 1) |
| Completion of a continuous around the world fibre-optic cable link | 1997 | Generally Correct (Major segment completion) | 1997 (e.g., FLAG Europe Asia Phase 1) |
| Creation of the SWIFT system for worldwide electronic interbank fund transfer | 1977 | Correct (Operations started) | 1977 |
| Introduction of the World Wide Web (www) | 1995 | Incorrect | 1989/1990 (Conception/Development), 1991 (First website), 1993 (Public release) |
The table clearly shows that the World Wide Web introduction is the only event paired with an incorrect year among the options.
| Tech Event | Key Year | Significance |
|---|---|---|
| First Active Communications Satellite (Telstar 1) | 1962 | Enabled transatlantic TV signals |
| SWIFT System Operations Begin | 1977 | Standardized secure financial messaging |
| World Wide Web Invented (Proposals/Development) | 1989/1990 | Foundation of the WWW |
| First World Wide Web Website Live | 1991 | WWW becomes functional |
| WWW Software Released to Public Domain | 1993 | Enabled rapid growth of the internet |
| Completion of Major Global Fibre-Optic Links (e.g., FLAG) | Late 1990s (e.g., 1997) | Significantly increased global internet capacity |
It's important to distinguish between the internet and the World Wide Web. The internet is a vast network of interconnected computers. It existed for many years before the WWW was created. The World Wide Web is an information system built on top of the internet, using technologies like HTML, URLs, and HTTP. It allows users to access interconnected documents (web pages) via web browsers.
The invention of the WWW by Tim Berners-Lee revolutionized how people access and share information online, leading to the internet as we know it today.
