OSI Layers and their work

OSI (Open system interconnection) Layers :- (1) Application Layer :-  Manipulation of data, mail service etc. are provided, uses web browser. (2) Presentation Layer :-  Perform by OS that converts HLL to MLL, maintain encryption & decryption. (3) Session Layer :- Manages conversation between two different applications, Manages session b/w source and destination. (4) Transport Layer :-  Decides data transmission should be on parallel or single path, It breaks message into packets & maintain it should reach destination with reliability. (5) Network Layer :-   Acts as network controller, Decides which route data should take. (6) Data Link Layer :- Error controlling, Error detection bits are used. (7) Physical Layer :- Activates, maintain  & deactivate Physical connection, It converts digital bits into electrical signals. BONUS FACTS  :- Hub :-  Works on Physical Layer. Switch :- Works on Data Link Layer. Bridge :- Works on Data Link Layer. ...
