Who coined the term 'Cyberspace'?

The term 'Cyberspace' was coined by science-fiction novelist William Gibson in his 1984 novel "Neuromancer." Gibson used the term to describe a virtual reality dataspace that served as the central backdrop for his narrative. His portrayal of cyberspace was innovative and foresaw the impact of electronic networks and computer systems on society. This concept has since evolved to encapsulate a range of digital environments including the internet and virtual realities.

The other options do not align with the origin of the term. While government agencies, technology companies, and cybersecurity experts may use the term or refer to cyberspace in their work, they did not create it. The significance of Gibson's contribution underscores the intersection of technology with culture and imagination, which helped frame our understanding of digital spaces.
