Etiquette in technology, colloquially referred to as netiquette is a term used to refer to the unofficial code of policies that encourage good behavior on the Internet which is used to regulate respect and polite behavior on social media platforms, online chatting sites, web forums, and other online engagement websites. The rules of etiquette that apply when communicating over the Internet are different from these applied when communicating in person or by audio (such as telephone) or photographic phone. It is a social code that is used in all places where one can interact with other human beings via the Internet, including text messaging, email, online games, Internet forums, chat rooms, and many more. Although social etiquette in real life is ingrained into our social life, netiquette is a fairly recent concept. It can be a challenge to communicate on the Internet without misunderstandings mainly because input from facial expressions and body language is absent in cyberspace. Therefore, several rules, in an attempt to safeguard against these misunderstandings and to discourage unfriendly behavior, are regularly put in place at many websites, and often enforced by moderation by the website's users or administrators. Netiquette, a colloquial portmanteau of network and etiquette or Internet and etiquette, is a set of social conventions that facilitate interaction over networks, ranging from Usenet and mailing lists to blogs and forums. Like the network itself, these developing norms remain in a state of flux and vary from community to community. The points most strongly emphasised about Usenet netiquette often include using simple electronic signatures, and avoiding multiposting, cross-posting, off-topic posting, hijacking a discussion thread, and other techniques used to minimize the effort required to read a post or a thread. Similarly, some Usenet guidelines call for use of unabbreviated English while users of instant messaging protocols like SMS occasionally encourage just the opposite, bolstering use of SMS language.
