In 2006, Nokia estimates 2 billion mobile phone subscribers. Today’s cellphones are mobiles; these can take and send pictures, connect to the internet, can send and receive text messages. 1.2 Internet, World Wide Web, & Cyberspace ⦁ World Wide Web It is the multimedia part of the internet. It is an interconnected system of servers that support specially formatted documents in multimedia form. It includes text, still images, moving images, sound. These things are responsible for the growth and popularity of the internet. ⦁ Cyberspace Term coined by William Gibson in Neuromancer (1984). They described it as a futuristic computer network where people “plugged” into directly with their brains.
