Online chat refers to a form of digital communication that allows real-time exchange of text messages between users. Its origins trace back to 1973 with the creation of Talkomatic, the first online chat system on the PLATO System. Since then, various advancements have shaped and enhanced this mode of communication. Notable figures like Tim Berners-Lee, Vint Cerf, Paul Baran, Emile Berliner, John Logie Baird, and Alexander Graham Bell have made significant contributions to its evolution. Online chat has impacted language use, leading to the emergence of new words and a unique chat etiquette, known as chatiquette. It also plays a crucial role in forming online identities and is a valuable resource for chat/text mining technologies. Critics, however, express concerns about its influence on grammar^[2] and proper English usage. Despite this, online chat remains an integral part of digital literacy, particularly among young people. It is now integrated into various platforms, including video-conferencing tools and web conferencing^[1] services. The development and use of online chat have been widely explored in academic research, focusing on its implications for language skills and communication.

Definições de termos

1. ↑ web conferencing. Web conferencing refers to the online service that allows for real-time meetings, presentations, and collaborations over the internet. This multifaceted technology allows participants to engage in digital meetings, typically using a combination of audio, video, and text communication. The software used can either be web-browser based, requiring no downloads, or it may need to be installed on the user's computer. It's often used for webinars - a blend of the words 'web' and 'seminar' - and for webcasts, which are similar to traditional broadcasts but over the internet. However, the lack of standardization in web conferencing technology can sometimes lead to interoperability issues. Various deployment models exist, including hosting services, software, and dedicated appliances. Over time, web conferencing has evolved, with a variety of platforms now available, each offering different features and capabilities.

2. ↑ grammar. Grammar, as an essential element of language, has a rich and diverse history. Originating from the Greek term for 'art of letters', systematic grammar first appeared in Iron Age India. It further developed in Latin in the 1st century BC, following Greek models. The evolution of grammar is influenced by usage, which often results in formal rules when represented in written form. However, this can also lead to differences between modern usage and accepted norms. Theoretical linguistics seeks to scientifically define the rules of grammar, with several approaches and frameworks available. Grammar is not only a description of the linguistic behavior of groups, but also plays a vital role in language acquisition and education. It is learned intuitively by native speakers and taught more directly to non-native speakers. The study of grammar in schools often leans towards prescriptive rules. Standards of language, often based on specific regions, are promoted in education, with many languages having multiple official standards. Various linguistic theories and notable works contribute to the understanding and study of grammar, exploring traditional terms and the cultural impacts of grammar.

Chat online (Wikipédia)

Chat online is any kind of communication over the Internet that offers a real-time transmission of text messages from sender to receiver. Chat messages are generally short in order to enable other participants to respond quickly. Thereby, a feeling similar to a spoken conversation is created, which distinguishes chatting from other text-based online communication forms such as Fóruns na Internet e correio eletrónico. Online chat may address point-to-point communications as well as multicast communications from one sender to many receivers and voice and video chat, or may be a feature of a web conferencing service.

In this typical online chat program, the window to the left shows a list of contacts, and the window to the right shows a conversation between the user and one of those contacts.

Online chat in a less stringent definition may be primarily any direct text-based or video-based (webcams), one-on-one chat or one-to-many group chat (formally also known as synchronous conferencing), using tools such as instant messengers, Internet Relay Chat (IRC), talkers and possibly MUDs or other jogos online. The expression online chat comes from the word chat which means "informal conversation". Online chat includes web-based applications that allow communication – often directly addressed, but anonymous between users in a multi-user environment. Conferência Web is a more specific online service, that is often sold as a service, hosted on a web server controlled by the vendor.
