OSI layer responsible for binary transmission cable specification and physical aspects of network communication?
physical layer
Which OSI layer is responsible for binary transmission cable specification and physical aspects of network communication?
Physical
What items are considered part of the physical layer of a network?
Modems Transmission media connectors Repeaters
The what layer in the OSI model arranges data into packets whereas the what layer prepares data for physical transmission?
network data-link
Which layer is the network support layer?
Physical, Data link and Network layers make the Network Support layers.
What is transmission layer?
physical
What the layer closest to the transmission medium?
physical layer.
Is the transmission medium a part of physical layer why or why not?
The Physical Layer defines the means of transmitting raw bits rather than logical data packets over a physical link connecting network nodes. The bit stream may be grouped into code words or symbols and converted to a physical signal that is transmitted over a hardware transmission medium. The Physical Layer provides an electrical, mechanical, and procedural interface to the transmission medium. The shapes and properties of the electrical connectors, the frequencies to broadcast on, the modulation scheme to use and similar low-level parameters, are specified here. Within the semantics of the OSI network architecture, the Physical Layer translates logical communications requests from the Data Link Layer into hardware-specific operations to affect transmission or reception of electronic signals.
What Translates network addresses into their physical counterparts?
Network Layer
Which osi layer is responsible for the mechanical connection to the network?
The Physical Layer
What resides at the physical layer of the OSI layer?
Interfaces used on the system to connect to Network devices reside on Physical layer.
What is layered network?
A layered network, or a network layer, is the set up of how data is sent over a network. Each layer has it's own responsibility by either capturing the data or routing it to a computer on the network.
