NETWORK LAYER
Open Systems Interconnection (OSI) model is the one which divides network communication process in to seven layers....
Since the ionosphere have different types of layers namely D,E and F layers. So when a pulse transmitted from transmitter it get deflected or we can say reflect by these different layers and reaches to the receiver.Thus the path followed by the pulse is the Actual path.The distance between the highest point of actual path and the earth surface is called Actual height.When a short pulse of energy sent vertically upward and traveling with the speed of light would reach taking the same two rays travel time as does the actual pulse reflected from the ionospheric layers. that height is known as Virtual height of an antenna.
The operating system has different layers. The different layers includes the shell, the utilities, the compilers, device drivers and the applications.
what is the meanin of file compatibility
Protocols at each of the OSI layers govern how they are to talk to each other. Each layer of the OSI model has different responsibilities and they may have multiple protocols that they could use. The sender and receiver in networks must agree on a common ground for communication, which is the protocol. Depending on what you are trying to accomplish there are different protocols at different layers of the OSI model. Basically, you need the two systems to agree on how to do that. That is the role of a protocol.
The different "layers" are classifications of horizontal sections of the atmosphere, volumes which exhibit different attributes. The high and low pressure regions are areas where the atmosphere is thicker or thinner.
There are different machines. For "sno-cones," ice is crushed into tiny pieces from ice cubes. For "shave ice" or what they call "sno-balls" in New Orleans, a different machine is used that literally uses steel blades to shave thin layers from a large, solid block of ice that it is inserted in the machine. By shaving off thin layers, a lot of air is held between the layers, creating a substance very much like snow, rather than slushed ice. http://www.hawaiianshavedice.com/shavicemac.html
They are different because different minerals can be found at different layers. Also, the layers closer to the core of the earth will become more hot, causing melted rock (magma) to form.
Because there different kind of layers and they each are totally different from each other!
how earthquakes helped in determining the different layers of earth
The entities comprising the layers on different machines are called peers.The peer may be processes,hardware devices or even human beings. In other words, it is the peers that communicate by using the protocol.
