The IP protocol deals only with packets, while the TCP enables two hosts to establish a connection and exchange streams of data. It can be divided into 5 layers.

A data sandbox, in the context of big data, is a scalable and developmental platform used to explore an organization's rich information sets through interaction and collaboration. It allows a company to realize its actual investment value in big data. A data sandbox is primarily explored by data View Full Term.

Osi Model Interview Questions & Answers

Client-server denotes a relationship between cooperating programs in an application, composed of clients initiating requests for services and servers providing that function or service. The client-server model, or client-server architecture, is a distributed application framework dividing tasks between servers and clients, which either reside in the same system or communicate through a computer network or the Internet. The client relies on sending a request to another program in order to access a service made available by a server. The server runs one or more programs that share resources with and distribute work among clients. The client server relationship communicates in a request—response messaging pattern and must adhere to a common communications protocol, which formally defines the rules, language, and dialog patterns to be used. TCP protocol maintains a connection until the client and server have completed the message exchange.

This chapter provides an overview of the Ethernet-to-the-Factory EttF solution architecture, as a means to describe the various systems, components, and their relation to each other to give context to the networking function and technical requirements. EttF is an architecture that provides network and security services to the devices, equipment, and applications found in industrial automation and control systems and integrates them into the wider enterprise network. The networking requirements of a production facility often differ from a typical IT network. This solution architecture overview provides the background and description of an industrial automation and control network model and highlights the differences between the EttF architecture and the IT network infrastructure. Reuse is an objective of any architecture, and this is the case with the EttF solution architecture. Industrial automation and control systems are deployed in a large variety of industries, such as automotive, pharmaceuticals, consumer goods, pulp and paper, oil and gas, and energy. Industrial automation and control systems are also deployed in a wide variety of types of manufacturing, such as batch, discrete, process, and hybrid manufacturing.

Although it started as a proprietary protocol it was released Royalty free in and became an OASIS standard in There is very little difference between v3. Here is a Github page detailing the main differences. You can download the specification here. If you are wondering what happened to 4 then see here.

Ethernet-to-the-Factory 1.2 Design and Implementation Guide

The Open Systems Interconnection model OSI model is a conceptual model that characterises and standardises the communication functions of a telecommunication or computing system without regard to its underlying internal structure and technology. Its goal is the interoperability of diverse communication systems with standard communication protocols. The model partitions the flow of data in a communication system into seven abstraction layers , from the physical implementation of transmitting bits across a communications medium to the highest-level representation of data of a distributed application. Each intermediate layer serves a class of functionality to the layer above it and is served by the layer below it. Classes of functionality are realized in software by standardized communication protocols. The OSI model was developed starting in the late s to support the emergence of the diverse computer networking methods that were competing for application in the large national networking efforts in France, the United Kingdom, and the United States. While attempting to provide a comprehensive description of networking, the model failed to garner reliance by the software architects in the design of the early Internet , which is reflected in the less prescriptive Internet Protocol Suite , principally sponsored under the auspices of the Internet Engineering Task Force IETF.

OSI Reference Model

When we are talking about layer 2 switches and layer 3 Ethernet switch , we are actually referring to the layers of a generic protocol model—Open Source Interconnect OSI model. It is a commonly used in describing network communications. The data communications between different networks are not possible if there are no common rules for transmitting and receiving the packets of data.

All these layers collaboratively work to transfer the data from one person to other across the globe. These OSI interview questions and answers framed with the expert knowledge, and it makes your path of getting the job in the domain hassle-free in the short interval. The job seeker will be able to answer the questions quite easily and become a preferred choice for the interviewer irrespective of the size of the company they choose to work.
