Answer the following questions of OSI reference model: Which layer is responsibl

Question

Answer the following questions of OSI reference model: Which layer is responsible for converting data packets from the Data Link layer into electrical signals? At which layer is routing implemented, enabling connections and path selection between two end systems? Which layer defines how data is formatted, presented, encoded, and converted for use on the network? Which layer is responsible for creating, managing and terminating sessions between applications? Which layer provides logical addressing that routers will use for path determination? Which layer specifies voltage, wire speed, and moves bits between devices? Which layer combines bits into bytes and bytes into frames, uses MAC addressing, and provide error detection? Which layer segments and resembles data into a data stream? Which layer provides interface for users to communicate with applications? What are the difference between OSI and TCP/IP model?

Explanation / Answer

Answer:

a) Physical Layer

b) Network Layer is responsible for routing

c) Physical Layer

d) Session Layer

e) Network Layer

f) Physical Layer

g) Data Link Layer

i) Transport Layer

j) Application layer

In the TCP/IP model Application , presentation and session layers are merged into a singel layer. In TCP/IP , Network Layer is called internet Layer. The last two layers of the OSI model : data link layer and physical layer are merged into one layer.
