All 802.x map to
1. Data Link
2. Physical
layer in OSI model.
No. Ethernet and token ring have now become standards. However, the access method and the standard are not always the same. Ethernet is based on IEEE 802.3 standards, but is not exactly the same as IEEE 802.3. Some vendors' IEEE 802.3 equipment will not work with ethernet. Token ring and 802.5 are the same, despite token ring's origins as an IBM proprietary standard. Non-IBM vendors can provide 802.5 equipment that will work with IBM token rings, provided the equipment follows 802.5 standards
802.11 and OSI are two different things. The 802.11 committee is responsible for setting the wireless standards for wireless communication. The OSI model is not a standard at all, but a theoretical model of how communications work and utilizes many standards in that process. The 802.11 standards are incorporated in the OSI model, at layer 1 and layer 2 of the model.
My Dell Inspriron doesn't have the IEEE fitting ,can this be fitted as an after marketproduct,. Dell replaced my faulty laptop in the rush I neglected to notice the paper work didn't show the IEEE. Downloading via bluetooth is much slower + I purchased at the time a few IEEE cables ( spares )Thanks.Steve.
All current Macs, including the MacBook Pro, conform to the IEEE 802.11 standard and will work with a/b/g and n networks.
Any Firewire adapter will work great with a dell notebook, as they all have a standard firewire outlet or can use an adapter card.
The Mac's AirPort card conforms to the standard IEEE 802.11 and should be recognised by a Linux installation. From personal experience it works fine with Ubuntu without any need for configuration.
It is work at Network layer.
Layer 1 - the physical layer
Application Layer
Layer 2 , Data Link Layer
Switches / Bridges and hubs work at data link layer, but there are layer three switches which operate at network layer. Dhruv
layer one
