 Layer seven of the OSI model
Application
Why are six of the OSI model
Presentation
What are five of the OSI model
Session
Layer four of the OSI model
Transport
Later three of the OSI model
Netwerk
Layer two of the OSI model
Datalink
Layer one of the OSI model
Physical
For layers 7, 6 and five data and instruction known as the – – – – – are generated by an application running on the source host
Payload
In the process of encapsulation a transport layer protocol usually either TCP or UDP adds a heter in front of the payload the header includes a port to ID the receiving application on the destinations host. The entire message then became a segment when using TCP or data gram.
What layer of the OSI model does this take place at

Layer 4
This lawyer as its own header in front of the past tense segment or datagram this header identifies the IP address of the destination host and the message is called a packetm
This happens at what layer of the OSI model
Layer 3 network layer
The package passed to the – – – – – – – – layer on the neck which encapsulates the data with its own header and trailer creating a frame
Layer 2 data link
The – – – – – layer on the neck receives the frame and places the actual transmission on the network
Physical layer
Searching host Diabulates the message at each liar in reverse order and then presents the pay load to the receiving ———-
Application
______________ also called networking devices or specialized devices that allow two or more networks or multiple parts of one that work to connect and exchange data
Connectivity devices
Each device is known by the innermost OSI layer header it
Read and processes
