Modern forms of communication include fax, email, video conferencing, the internet, and websites. Fax allows for the fast transmission of documents but lacks privacy. Email provides a cheap and easy way to communicate with many people simultaneously but can enable viruses and spam. Video conferencing facilitates face-to-face communication from anywhere in the world and saves travel costs, though it requires a strong internet connection. The internet grants access to vast amounts of information and enables global communication, but can enable cybercrime and internet addiction. Websites help businesses connect with customers worldwide and provide constant access to learning, but may contain misleading information and require viewing advertisements.
