Physical and MAC addressing are found in the OSI layer 2?

OSI (Open Systems Interconnection) model's Layer 2, also known as the Data Link layer, employs a type of addressing known as MAC (Media Access Control) addressing. A MAC address is a hardware identification number that uniquely identifies each device on a network. The MAC address is assigned by the manufacturer and stored in the network card, making it a permanent, physical address. It consists of six groups of two hexadecimal digits. The first half of a MAC address contains the ID number of the adapter manufacturer, while the second half represents the serial number assigned to the adapter by the manufacturer. MAC addresses are crucial in the process of delivering data packets directly to a device within a network.

∙ 14y agoAt layer 2, the addressing is called "physical addressing".
The most common layer-2 technology (in the case of LANs) is Ethernet; in the case of Ethernet, every network card (and similar equipment that connects to the network, e.g. router interface) has a serial number, called a "MAC address". This is used for addressing.
At layer 2, the addressing is called "physical addressing".

Which data link layer addressing scheme is used in a point-to-point logical topology?
Layer 2 addressing not required for this topology
What layer combines bits into bytes and bytes into frames and uses mac addressing?
Data Link
What is the role of the data link layer protocols in data transmission?
The role is to transfer frames to packets
Which osi layer addresses data messages?
The OSI model has seven layers whereby each layer has its function. The Data Link Layer is responsible for addressing data messages so that they reach their destination correctly.
If data link layer detect error why do you think we need transport layer?
because in the data link layer two routers communitate directly via a physical channel , whereas at the transport layer this physical channel is replaced by the entire subnet. In the data link layer ,it is not necessary for a router to specify which router it wants to talk to each outgoing line uniquely specifies a panicular router . In the transport layer explicit addressing of destinations is required.

Data Link
What kind of address scheme is used at data link layer?
Data link layer transforms the physical layer and makes it appear error free. Data link layer is responsible for physical addressing. It has some other functions like error control, flow control and access control.

Which layer of the OSI model is primarily concerned with accessing the physical media and physical addressing?
Data Link
Which layer of the OSI model is primarily concerned with accessing the physical media and physical addressin?
The Physical layer is responsible for the actual hardware connection. The physical addressing is handled by the Data Link Layer.
What primary three functions does data link layer encapsulation provide?
* addressing * error detection * frame delimiting
Bridge is used in which OSI layer?
Layer 2 (Data Link Layer) http://compnetworking.about.com/cs/internetworking/g/bldef_bridge.htm

What are the three primary functions provided by Layer 2 data encapsulation?
Primary functions provided by Layer 2 data encapsulation include data link layer addressing, and the detection of errors via cyclic redundancy check calculations. An additional function is delimiting groups of bits into frames.
Bits are packaged into frames at which layer of the OSI model?
Data link layer
