If your possible answers are
<span>stock
action
barrel
trigger

If I am at the station that the train is approaching, and if the train is making some kind of steady sound, then as the train draws closer, I hear the amplitude of the sound steadily increasing ... it gets louder and louder as the train gets closer and closer to me.
(The frequency of the sound I hear is higher than the frequency of the sound the train is actually making, but I don't know that, because I have no idea what frequency sound the train is actually making.)
=================================
If anybody tries to tell you that the frequency of the sound from the train keeps getting higher and higher, please tell that person to come see me, and I will straighten him out. It doesn't.
6th layer of OSI model ensures complete and rebel delivery of data packets.
(presentation layer is the 6th layer.)
OSI - Open system Interconnection is a conceptual model that provides a common basis for the condition.
It is a reference model for how application communicate over a network.
This model describes 7 layer that computer system used to communicate over a network.
It was the model for network communication and adopted by all major computer and companies.
The complications between US computing system are split in several layers.
- physical.
- Datalink.
- Network.
- Transport.
- Session
- Presentation
- Application.
The purpose of OSI reference model is to guide technology developer.
