MAC address
Last modified: Tuesday, August 31, 2004
Short for Media Access Control address, a hardware address that uniquely identifies each node of a network. In IEEE 802 networks, the Data Link Control (DLC) layer of the OSI Reference Model is divided into two sublayers: the Logical Link Control (LLC) layer and the Media Access Control (MAC) layer. The MAC layer interfaces directly with the network medium. Consequently,
each different type of network medium requires a different MAC layer.
On networks that do not conform to the IEEE 802 standards but do conform to the OSI Reference Model, the node address is called the Data Link Control (DLC) address
- Zkratka pro Media Access Control address, HW-adresa, ktera jednoznacne identifikuje kazdy uzel v siti. V sitich IEEE 802 je DLC-vrstva (Data Link Control) OSI-referencniho modelu rozdelena do 2 podvrstev: LLC (Logical Link Control) a MAC (Media Access Control). Vrstva MAC hranici primo se sitovym mediem. V dusledku toho vyzaduje kazdy typ sitoveho media jinou MAC-vrstvu.
V sitich, ktere neodpovidaji standardum IEEE 802, ale odpovidaji referencnimu modelu OSI, se uzlove adresy nazyvaji DLC-adresy (Data Link Control).

node = uzel
(1) In networks, a processing location. A node can be a computer or some other device, such as a printer. Every node has a unique network address, sometimes called a Data Link Control (DLC) address or Media Access Control (MAC) address.
- Misto procesu v sitich. Uzel muze byt pocitac nebo jine zarizeni, jako napr. tiskarna. Kazdy uzel ma jedinecnou sitovou adresu, nekdy nazyvanou DLC-adresa (Data Link Control) nebo MAC-adresa (Media Access Control).
(2) In tree structures, a point where two or more lines meet.
- Ve stromovych strukturach bod, kde se setkavaji 2 nebo vice linii.
