What is same layer interaction?
|
Communication that happens between two devices at the same layer through the use of headers.
The two computers use a protocol to communicate with the same layer on another computer. The protocol defined by each layer uses a header that is transmitted between the computers, to communicate what each computer wants to do. |
|
The TCP/IP transport layer consists of two main protocol options: What are they?
|
The Transmission Control Protocol (TCP) and the User Datagram Protocol (UDP).

The term encapsulation refers to the process
of putting headers and trailers around some data. |
|
What is the process by which a TCP/IP host sends data (5 Steps)
|
Step 1 Create and encapsulate the application data with any required application
layer headers. For example, the HTTP OK message can be returned in an HTTP header, followed by part of the contents of a web page. Step 2 Encapsulate the data supplied by the application layer inside a transport layer header. For end-user applications, a TCP or UDP header is typically used. Step 3 Encapsulate the data supplied by the transport layer inside an internet layer (IP) header. IP is the only protocol available in the TCP/IP network model. Step 4 Encapsulate the data supplied by the internet layer inside a network access layer header and trailer. This is the only layer that uses both a header and a trailer. Step 5 Transmit the bits. The physical layer encodes a signal onto the medium to transmit the frame. |
