The Physical Layer is the lowest layer of the TCP/IP model. It deals with data in the form of bits. This layer mainly handles the host-to-host communication in the network. (10 Feb 2020)
Layers of a Router
The TCP/IP model
Sometimes referred to as a protocol stack, can be considered a condensed version of the OSI model.
Layer 1 (Network Access): Also called the Link or Network Interface layer.
Layer 2 (Internet): This layer is similar to the OSI model’s L3.
Layer 3 (Transport): Also called the Host-to-Host layer.
How TCP Works Step by Step
TCP is a connection-oriented protocol.
To transmit segments from the sender to the receiver, a TCP connection needs to be established between them.
TCP connections go through a complete life cycle. Roughly, the stages of a TCP connection are: establish connection, transfer data, terminate connection. (10 Nov 2019)
TCP/IP Protocol
What is TCP/IP ppt?
It uses checksums, acknowledgments, and timeouts to control transmissions and end-to-end verification.
Unlike the OSI model, TCP/IP treats reliability as an end-to-end problem.
Question:
Which among the four layers of TCP/IP is analogous to the physical and the data link layers of an OSI model?
Network Access Layer: This layer corresponds to the combination of the Data Link Layer and Physical Layer of the OSI model. (30 Sep 2020)
