Most Common Interview Questions on OSI model:-If you are looking for a network Engineer , Network Administrator or any other IT administrator job. OSI model is one the most common topic for interviewer to ask you. Today i am going to cover-up most of the interview questions related to OSI model. (Q) What is OSI Model ? Ans :- Check my article The OSI Model’s Seven Layers Defined and Functions Explained (Q) What is TCP ? Ans :- Check my article What is Transmission Control Protocol (TCP ) (Q) What is differences between TCP and UDP ? Ans :- Check my article What is differences between TCP and UDP (Q) Which layer is responsible for converting data packets from the Data Link layer into electrical signals ? Ans :- Physical Layer Explanation :- The Physical layer takes frames from the Data Link Layer and encodes the 1s and 0s into a digital signal for transmission on the network medium. (Q) At which layer is routing implemented, enabling connections and path selection between two end systems. ? Ans :- Network Layer Explanation :- The Network layer provides routing through an inter-network and logical addressing. (Q) Which layer defines how data is formatted, presented, encoded,and converted for use on the network ? Ans :- Presentation Layer Explanation :- The Presentation layer makes sure that data is in readable format for the application layer. (Q) Which layer is responsible for creating, managing and terminating sessions between applications ? Ans :- Session Explanation :- The Session layer setup, maintains, and terminates session between applications. (Q) Which layer provides logical addressing that routers will use for path determination ? Ans :- Network Layer Explanation :- The Network layer provides logical addressing, typically IP addressing and routing. (Q) Which layer specifies voltage, wire speed, and pinout cables and moves bits between devices ? Ans :- Physical Layer Explanation :- The Physical layer is responsible for the electrical and mechanical connections between devices. (Q) Which layer combines bits into bytes and bytes into frames, uses MAC addressing, and provide error detection ? Ans :- Data Link Layer Explanation :- The Data-link layer is responsible for the framing of data packets. (Q) Which layer is responsible for keeping the data from different applications separate on the network ? Ans :- Session layer Explanation :- The Session layer creates sessions between different host applications. (Q) Which layer segments and resembles data into a data stream ? Ans :- Transport (Q) Which layer provides the physical transmission of the data and handless error notification, network topology, and flow control ? Ans :- Data Link Layer (Q) Which Layer manages device addressing, tracks the location of devices on the network, and determine the best way to move data ? Ans :- Network layer (Q) What is Data Encapsulation ? or Order of Encapsulation ? or Which layer is represented by frames ? Which layer i
