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
OSI Model layer functions (cont.): Network: Provides best path selection and IP addressing Data Link: Defines how computers access the media Physical: Converts bits into signals and defines media and connectors The IEEE 802 project defines a set of networking standards to ensure that network interfaces and cabling from multiple manufacturers would be compatible. The IEEE 802.2 standard specifies a Logical Link Control (LLC) and Media Access Control (MAC) sublayer
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 4 : The Transport Layer
