How many bits are there in a data link layer ethernet address?
What are two functions of the data link layer?
What are two functions of the data link layer? (Choose two.) It segments and reorders the data. It exchanges data between programs that are running on the source and destination hosts. ***It controls how data is placed onto the media. It generates signals to represent the bits in each frame. ***It encapsulates each packet with a header and a trailer to transfer it across the local media. ============================ 1. Data Link layer do not reorder data - this is the job of Transport Layer 2. Programs are at Aplication Layer 4. Physical Layer generate signals
Bits are packaged into frames at which layer of the OSI model?
Data link layer
What layer arrange signals into logical units of information called frame?
Layer 2 or the 'Data' layer of the OSI model encapsulates either 'bits' from the physical layer (1)- moving up the TCP stack or 'Packets' from the Network layer (3)- going down the the stack. 7 - Application Layer DATA 6 - Presentation Layer DATA 5 - Session Layer DATA 4 - Transport Layer SEGMENT 3 - Network Layer PACKET 2 - Data Layer (Incorporating LLC and MAC) FRAME 1 - Physical Layer BIT A good nmemonic for remembering the data encapsulation in the OSI model is 'Don't Some Peolple Fry Bacon' - Data, Segments, Packets, Bits.
Which OSI layer converts bits into signals for outgoing messages and signals into bits for incoming messages?
The OSI layer responsible for converting bits into signals for outgoing messages and signals into bits for incoming messages is the Physical layer. This layer handles the transmission and reception of raw bitstreams over a physical medium, such as cables or wireless signals. It defines the electrical, mechanical, and procedural specifications for transmitting data.
Suppose that electromagnetic interference changes the data unit 00110001100 to 01110000100?
7 Bits

Does encoding occur at layer two of the osi reference model?
the physical layer (layer 1) manages hardware connections, handles sending and receiving binary signals, and handles encoding of bits.
What OSI layer Moves bits between devices?
The OSI layer that moves bits between devices is the Physical layer, which is the first layer of the OSI model. It is responsible for the transmission and reception of raw binary data over a physical medium, such as cables or wireless signals. This layer defines the electrical, mechanical, and procedural aspects required for the physical connection between devices.
What are the three concerns when the physical layer encodes bits?
When the Physical layer encodes the bits into the signals for a particular medium, it must also distinguish where one frame ends and the next frame begins. Otherwise, the devices on the media would not recognize when a frame has been fully received.
How are digital signals?
Digital signals are measured in bits per second (bps).
