The five layers in Internet Protocol stack is Application, Transport, Network, Data link and Physical layer. The internet protocol stack model is also called the TCP/IP model and it’s used in modern Internet Communication. 2.The number of layers in ISO OSI reference model is __________
Module 01 1.How many layers are present in the Internet protocol stack (TCP/IP model)? a) 5 b) 7 c) 6 d) 10 Answer: a Explanation: There are five layers in the Internet Protocol stack. The five layers in Internet Protocol stack is Application, Transport, Network, Data link and Physical layer.
a) End system b) NIC c) Ethernet d) Packet transport Answer: a Explanation: Not only application layer, but presentation layer, session layer and transport layer are also implemented in the end system.
The internet protocol stack model is also called the TCP/IP model and it’s used in modern Internet Communication. 2.The number of layers in ISO OSI reference model is __________
This layered architecture is called the five-layer internet protocol stack. While sending a message, the message travels through each layer one by one, starting from the application layer. Each layer adds its own relevant information to the data packet.
The TCP/IP model is based on a five-layer model for networking. From bottom (the link) to top (the user application), these are the physical, data link, net- work, transport, and application layers. Not all layers are completely defined by the model, so these layers are “filled in” by external standards and protocols.

The four layers of original TCP/IP model are Application Layer, Transport Layer, Internet Layer and Network Access Layer.
In the OSI reference model, the communications between a computing system are split into seven different abstraction layers: Physical, Data Link, Network, Transport, Session, Presentation, and Application.
The protocol stack or network stack is an implementation of a computer networking protocol suite or protocol family. Some of these terms are used interchangeably but strictly speaking, the suite is the definition of the communication protocols, and the stack is the software implementation of them.
There are three main types of network protocols. These include network management protocols, network communication protocols and network security protocols: Communication protocols include basic data communication tools like TCP/IP and HTTP.
The most significant protocol at layer 3 (also called the network layer) is the Internet Protocol, or IP. IP is the standard for routing packets across interconnected networks--hence, the name internet. It is an encapsulating protocol similar to the way Ethernet is an encapsulating protocol.
Layer 2 protocols or network L2 protocols are a list of communication protocols used by Layer 2 devices (such as network interface cards (NIC), switches, multiport bridges, etc.) to transfer data in a wide area network, or between one node to another in a local area network.
A layer 4 load-balancer takes routing decision based on IPs and TCP or UDP ports. It has a packet view of the traffic exchanged between the client and a server which means it takes decisions packet by packet. The layer 4 connection is established between the client and the server.
