What is a primary role of the physical layer in transmitting data on the network?
create the signals that represent the bits in each frame on to the media
How many bits are there in a data link layer Ethernet address?
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.
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 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).

What transfer sends data in many bits simulaneously?
Parallel signals send multiple bits or entire bytes at a time. The parallel port was used mainly for printers.
What is physical layer?
In the Open Systems Interconnection (OSI)communications model, the physical layer supports the electrical or mechanical interface to the physical medium. For example, this layer determines how to put a stream of bits from the upper (data link) layer on to the pins for a parallel printer interface, an optical fiber transmitter, or a radio carrier. The physical layer is usually a combination of software and hardware programming and may include electromechanical devices. It does not include the physical media as such.
