In a wireless network, the data link layer manages the communication between devices over the radio frequency medium. It is responsible for framing data packets, addressing, and error detection and correction. This layer utilizes protocols like IEEE 802.11 (Wi-Fi) to handle medium access control (MAC), which ensures that multiple devices can share the same frequency without data collisions. Additionally, the data link layer establishes a reliable link by managing signal quality and retransmissions when necessary.

What is layered network?
A layered network, or a network layer, is the set up of how data is sent over a network. Each layer has it's own responsibility by either capturing the data or routing it to a computer on the network.
What type of device is switch?
A Switch is a Layer 2 device as they operate in the data link layer
Bridge is used in which OSI layer?
Layer 2 (Data Link Layer) http://compnetworking.about.com/cs/internetworking/g/bldef_bridge.htm
Explain the principal responsibility of the network layer and data link layer in a Wide Area Network in detail?
the network layer is the same as the data link layer, they do the same thing. that is that they communicat with the network to send packets of data...
Which layer is the network support layer?
Physical, Data link and Network layers make the Network Support layers.
What are three fundemental functions of the physical layer?
Definition of Hardware Specifications: The details of operation of cables, connectors, wireless radio transceivers, network interface cards and other hardware devices are generally a function of the physical layer (although also partially the data link layer; see below).Encoding and Signaling: The physical layer is responsible for various encoding and signaling functions that transform the data from bits that reside within a computer or other device into signals that can be sent over the network.Data Transmission and Reception: After encoding the data appropriately, the physical layer actually transmits the data, and of course, receives it. Note that this applies equally to wired and wireless networks, even if there is no tangible cable in a wireless network!Topology and Physical Network Design: The physical layer is also considered the domain of many hardware-related network design issues, such as LAN and WAN topology.
Which layer of the OSI model encapsulates Network layer pockets?
the network layer --> check your question. ^^^^^^^^^^^^^^^^^^^^^^^^^^^ That is totally not the right answer, how about you actually read the book for the course. It is the data link layer that does encapsulation. I agree - its the Data Link Layer which encapsulates the Network layer...NOT the Network Layer.
Which osi layer uses access points?
Access points operate primarily at the Data Link layer (Layer 2) of the OSI model, where they facilitate wireless communication between devices on a local area network (LAN). They manage the data frames and handle MAC addressing, allowing devices to connect to the network. Additionally, access points can also interact with the Network layer (Layer 3) for IP addressing and routing functions.
What is the highest layer of the OSI model used by router?
Router works in Network Layer of OSI model
Does it cost to use internet on iphone?
When your on a wireless network nope :) When your off your wireless network Yes you are using your data usages!
Are frames in the network layer?
No. Frames are used on the data-link (layer 2) layer. Packets are used at the Network (layer 3) layer.
Which osi layer encapsulates data into packets?
network layer
