Cyberspace is the complex environment of interdependent networks of IT infrastructures including the public Internet, various private “Internets” such as Internet2 or the US military’s Secret Internet Protocol Router Network (SIPRNet), telecommunications networks, computer systems, and embedded processors and controllers in technical industries.
Cyberspace is the virtual world we all interact with in our daily lives to communicate, share, and do business with one another across the globe. This virtual world grows every day with users finding new and innovative ways to communicate and collaborate with each other; whether it’s a cool new communications tool, sleek new operating system, or a popular social media site.
