Définitions des termes
1. technologie. La technologie, dérivée des mots grecs signifiant artisanat et connaissance, est un terme général qui désigne les outils, les machines et les systèmes mis au point par l'homme pour résoudre des problèmes ou atteindre des objectifs. Née avec des outils primitifs comme les haches de pierre et la découverte du feu, la technologie a évolué de manière significative tout au long de l'histoire de l'humanité. Elle a joué un rôle déterminant à différentes époques, depuis l'invention de la roue et des systèmes d'irrigation avancés dans les civilisations anciennes jusqu'à la naissance des universités et de la presse à imprimer au cours des périodes médiévale et de la Renaissance. La révolution industrielle du XVIIIe siècle a marqué un tournant important dans la production de masse et l'innovation, donnant naissance aux technologies modernes telles que l'électricité, l'automobile et les plates-formes de communication numérique. Aujourd'hui, la technologie fait partie intégrante de divers aspects de la vie et de la société, stimulant la croissance économique et les changements sociétaux, tout en suscitant des préoccupations en matière de sécurité, de respect de la vie privée et d'incidences sur l'environnement. L'avenir de la technologie devrait apporter encore plus de progrès, avec l'essor de l'intelligence artificielle qui devrait avoir des implications significatives sur le marché du travail.
2. vie privée. La protection de la vie privée est un concept fondamental qui a évolué au cours de l'histoire et qui continue de façonner notre discours sociétal. Historiquement, il est issu de débats philosophiques, avec des figures comme Aristote et John Locke qui en ont posé les bases. La protection de la vie privée est également liée à des questions juridiques et éthiques, comme en témoignent les arrêts historiques de la Cour suprême et les révélations telles que celles d'Edward Snowden. Les progrès technologiques ont à la fois remis en question et renforcé la protection de la vie privée, en introduisant de nouvelles menaces et de nouvelles mesures de protection. Les normes de protection de la vie privée varient d'un pays à l'autre et d'une organisation internationale à l'autre. À l'ère numérique, la vie privée est confrontée à de nouveaux défis et considérations, tels que l'utilisation des médias sociaux, la culture du selfie et les services de géolocalisation. Ce concept englobe le droit d'un individu à garder ses informations personnelles secrètes et à l'abri de toute intrusion non autorisée.

A service de réseau social ou SNS (sometimes called a social networking site) is a type of online médias sociaux platform which people use to build les réseaux sociaux ou social relationships with other people who share similar personal or career content, interests, activities, backgrounds or real-life connections.

Social networking services vary in format and the number of features. They can incorporate a range of new information and communication tools, operating on bureaux and on ordinateurs portables, on mobile devices such as tablet computers et smartphones. This may feature digital photo/video/sharing and diary entries online (blogging). Online community services are sometimes considered social-network services by developers and users, though in a broader sense, a social-network service usually provides an individual-centered service whereas online community services are groups centered. Generally defined as "websites that facilitate the building of a network of contacts in order to exchange various types of content online," social networking sites provide a space for interaction to continue beyond in-person interactions. These computer mediated interactions link members of various networks and may help to create, sustain and develop new social and professional relationships.

Social networking sites allow users to share ideas, digital photos and videos, posts, and to inform others about online or real-world activities and events with people within their social network. While in-person social networking – such as gathering in a village market to talk about events – has existed since the earliest development of towns, the web enables people to connect with others who live in different locations across the globe (dependent on access to an Internet connection to do so). Depending on the platform, members may be able to contact any other member. In other cases, members can contact anyone they have a connection to, and subsequently anyone that contact has a connection to, and so on. The success of social networking services can be seen in their dominance in society today, with X (formerly Twitter) being referred to as "world town square"[by whom?] that offers its users a real-time activity, like contacting anyone including friends, sharing images, videos and texts in form of "tweets". Facebook having a massive 2.13 billion active monthly users and an average of 1.4 billion daily active users in 2017. LinkedIn, a career-oriented social-networking service, generally requires that a member personally know another member in real life before they contact them online. Some services require members to have a preexisting connection to contact other members. With COVID-19, Zoom, a videoconferencing platform, has taken an integral place to connect people located around the world and facilitate many online environments such as school, university, work and government meetings.

The main types of social networking services contain category places (such as age or occupation or religion), means to connect with friends (usually with self-description pages), and a recommendation system linked to trust. One can categorize social-network services into four types:

  • socialization social network services used primarily for socializing with existing friends or users (e.g., Facebook, Instagram, Twitter/X)
  • online social networks are decentralized and distributed computer networks where users communicate with each other through Internet services.
  • networking social network services used primarily for non-social interpersonal communication (e.g., LinkedIn, a career- and employment-oriented site)
  • social navigation social network services used primarily for helping users to find specific information or resources (e.g., Goodreads for books, Reddit)

There have been attempts to standardize these services to avoid the need to duplicate entries of friends and interests (see the FOAF standard). A study reveals that India recorded world's largest growth in terms of social media users in 2013. A 2013 survey found that 73% of U.S. adults use social-networking sites.
