Also shown in this example (shaded in yellow) is the network's connection to the Internet via fixed-line means. A local area network (LAN) is a computer network that interconnects computers within a limited area such as a residence, campus, or building, [1] [2] [3] and has its network equipment and interconnects locally managed. LANs facilitate ...
A home network or home area network (HAN) is a type of computer network, specifically a type of local area network (LAN), [1] that facilitates communication among devices within the close vicinity of a home.
IEEE 802.3 is a working group and a collection of standards defining the physical layer and data link layer's media access control (MAC) of wired Ethernet.The standards are produced by the working group of the Institute of Electrical and Electronics Engineers (IEEE).
The services and protocols specified in IEEE 802 map to the lower two layers (data link and physical) of the seven-layer Open Systems Interconnection (OSI) networking reference model. IEEE 802 divides the OSI data link layer into two sub-layers: logical link control (LLC) and medium access control (MAC), as follows: Data link layer. LLC sublayer
In some applications there is an advantage to being able to designate one station having a higher priority. Token Ring specifies an optional scheme of this sort, as does the CAN Bus, (widely used in automotive applications) – but Ethernet does not. In the Token Ring priority MAC, eight priority levels, 0–7, are used.
Ethernet over twisted pair cabling and Wi-Fi are the two most common technologies used to build LANs today, but ARCNET, Token Ring, LocalTalk, FDDI, and other technologies were used in the past. Ethernet is the name of the IEEE 802.3 standard for physical LAN communication [ 40 ] and Wi-Fi is a trade name for a wireless local area network (WLAN ...
A metropolitan area network (MAN) is a computer network that interconnects users with computer resources in a geographic region of the size of a metropolitan area.The term MAN is applied to the interconnection of local area networks (LANs) in a city into a single larger network which may then also offer efficient connection to a wide area network.
The general concept of virtual LANs. A virtual local area network (VLAN) is any broadcast domain that is partitioned and isolated in a computer network at the data link layer (OSI layer 2). [2] [3] In this context, virtual refers to a physical object recreated and altered by additional logic, within the local area network. Basically, a VLAN ...
