Network interface controller.
A MAC Address is a unique bit network hardware identifier that is burned into a ROM chip on the NIC to identify that device on the network. The first bits is called the Organizationally Unique Identifier OUI and is largely manufacturer dependent. Each OUI allows for ,, Unique NIC Addresses.Smaller manufacturers that do not have a need for over unique NIC addresses may opt to purchase an Individual Address Block IAB instead. An IAB consists of the bit OUI, plus a bit extension taken from the potential NIC portion of the MAC addressA wireless network interface controller WNIC is a network card which connects to a radiobased computer network, unlike a regular network interface controller NIC which connects to a wirebased network such as token ring or ethernet. A WNIC, just like a NIC, works on the Layer and Layer of the OSI Model.
A WNIC is an essential component for wireless desktop computer. This card uses an antenna to communicate through microwaves. A WNIC in a desktop computer usually is connected using the PCI bus. Other connectivity options are USB and PC card. In an infrastructure mode network the WNIC needs an access point all data is transferred using the access point as the central hub. All wireless nodes in an infrastructure mode network connect to an access point. All nodes connecting to the access point must have the same service set identifier SSID as the access point, and if the access point is enabled with WEP they must have the same WEP key or other authentication parameters.In an adhoc mode network the WNIC does not require an access point, but rather can directly interface with all other wireless nodes directly. All the nodes in an adhoc network must have the same channel and SSID.
