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.
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
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.
The number of bits assigned to the host in an IP address determines the maximum number of devices that can be connected to a particular network. Specifically, it defines the size of the host portion of the address, which dictates how many unique addresses are available for devices within that network. The more bits allocated to the host, the larger the potential number of devices, but this reduces the number of bits available for network identification. Conversely, fewer host bits allow for more networks but limit the number of devices per network.
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.

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.
