Ethernet (/ ˈ iː θ ər n ɛ t / EE-thər-net) is a family of wired computer networking technologies commonly used in local area networks (LAN), metropolitan area networks (MAN) and wide area networks (WAN). [1] It was commercially introduced in 1980 and first standardized in 1983 as IEEE 802.3.
Power over Ethernet (PoE) describes any of several standards or ad hoc systems that pass electric power along with data on twisted-pair Ethernet cabling. This allows a single cable to provide both a data connection and enough electricity to power networked devices such as wireless access points (WAPs), IP cameras and VoIP phones .
A photo from the world's largest LAN party, DreamHack A LAN party is a social gathering of participants with personal computers or compatible game consoles, where a local area network (LAN) connection is established between the devices using a router or switch, primarily for the purpose of playing multiplayer video games together.
A multiplayer video game is a video game in which more than one person can play in the same game environment at the same time, [1] either locally on the same computing system (couch co-op), on different computing systems via a local area network, or via a wide area network, most commonly the Internet (e.g. World of Warcraft, Call of Duty, DayZ).
Nintendo remained cautious and terse with its online strategy for the remainder of the system's lifespan while competitors Microsoft and Sony were advancing their online gaming business. [ 10 ] [ 11 ] Months after the system's release, Nintendo stated it was researching online projects internally, but not planning any public demonstrations. [ 12 ]
Generally, layers are named by their specifications: [8] 10, 100, 1000, 10G, ... – the nominal, usable speed at the top of the physical layer (no suffix = megabit/s, G = gigabit/s), excluding line codes but including other physical layer overhead (preamble, SFD, IPG); some WAN PHYs (W) run at slightly reduced bitrates for compatibility reasons; encoded PHY sublayers usually run at higher ...
The textbook definition of a WAN is a computer network spanning regions, countries, or even the world. [ 3 ] [ 4 ] However, in terms of the application of communication protocols and concepts, it may be best to view WANs as computer networking technologies used to transmit data over long distances, and between different networks.
This is generally a local area network (LAN) technology with some wide area network (WAN) applications. Physical connections are made between nodes and/or infrastructure devices (hubs, switches, routers) by various types of copper or fiber cable. 802.3 is a technology that supports the IEEE 802.1 network architecture.
