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.

1) Physical layer is the first layer. 2) The simplest ones operate at the physical layer are: Repeaters, conventional hubs and transceivers. 3)These devices have absolutely no knowledge of the contents of a message. They just take input bits and send them as output. Cheers, AceInfo Solutions.

How many bits are there in a data link layer ethernet address?
group of wires or lines that are used to transfer adress between microprocesssor and i/o devices one way and of 20 bits while data bus uses bothway transfer of data between microprocessor and i/o devices of 16 bits
Data link 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.
Living in 8 Bits - 2010 Special Moves 3-2 was released on: USA: 23 February 2012
The functions of the physical layer of the OSI model include data encoding, and transmission of the unstructured raw bit stream. It also includes description of the optical, mechanical, and electrical interfaces to the physical medium.
8 bits totals one byte where one byte is roughly a single character such as 'A' or '1'
