DefinitionCyberspace (サイバー空間) is the virtual space connected by the internet and other networks, where people and organizations exchange information and carry out activities.
ExplanationIt refers to a place built on communication lines and computers, as opposed to physical places such as streets and buildings. Shopping, government procedures, business operations, and many other social and economic activities happen there, so damage done in it turns directly into real-world losses.
AnalogyPicture a second town alongside the one linked by roads and stations, this one linked by communication lines, where shops still open, people still gather, and deals still get made.
Memory hookThe word cyberspace spread from the novels of science fiction writer William Gibson.
