Un réseau local, souvent désigné par l'acronyme anglais LAN de Local Area Network, est un réseau informatique tel que les terminaux qui y participent (ordinateurs, etc.) s'envoient des trames au niveau de la couche de liaison sans utiliser d’accès à internet. On définit aussi le LAN par le domaine de diffusion, c'est-à-dire l'ensemble des stations qui reçoivent une même trame de diffusion (broadcast frame). Au niveau de l'adressage IP, un réseau local correspond généralement à un sous-réseau IP (même préfixe d'adresse IP). On interconnecte les réseaux locaux au moyen de routeurs.
Une autre approche consiste à définir le réseau local par sa taille physique. C'est généralement un réseau à une échelle géographique relativement restreinte, par exemple une salle informatique, une habitation particulière, un bâtiment ou un site d'entreprise.
the Ethernet and Wi-Fi speeds have increased. The rise of virtualization has fueled the development of virtual LANs (VLANs) which allows network administrators to logically group network nodes and partition their networks without the need for major infrastructure changes.
Local Area Network:which means desktops,laptops,wireless are connected to L2 or L3 switches.
LAN is stand for local area network and use in small office home office.
A local area network may serve as few as two or three users (for example, in a home network) or as many hundreds of users. Ethernet and Wi-Fi are the two most commonly used LAN technologies. Other LAN technologies, including Token Ring, Fiber Distributed Data Interface and ARCNET have lost favor as Ethernet and Wi-Fi speeds have increased. The rise of virtualization has fueled the development of virtual LANs (VLANs) which allows network administrators to logically group network nodes and partition their networks without the need for major infrastructure changes.
Typically, a suite of application programs can be kept on the LAN server. Users who need an application frequently can download it once and then run it from their local device. Users can order printing and other services as needed through applications run on the LAN server. A user can share files with others stored on the LAN server; read and write access is maintained by a network administrator. A LAN server may also be used as a Web server if safeguards are taken to secure internal applications and data from outside access. In some situations, a wireless LAN, or Wi-Fi, may be preferable to a wired LAN because of its flexibility and cost. Companies are assessing WLANs as a replacement for their wired infrastructures as the number of smartphones, tablets and other mobile devices proliferates.

LAN is short for Local Area Network. It refers to the connection between computers and other network devices that are located within a small physical location

A local area network (LAN) is a group of computers and associated devices that share a common communications line or wireless link to a server. Typically, a LAN encompasses computers and peripherals connected to a server within a small geographic area such as an office building or home. Computers and other mobile devices can share resources such as a printer or network storage.
LAN or Local Area Network is a group of interconnected devices with a common media either Wired or Wireless within a small area to share necessary resources.
The acronym of LAN is "Local Area Network". LAN are commonly used at home and office.
