Router work in which layer of osi model?
Routers work in layers two, three, and four layer 1 Physical (copper, fiber,...) layer 2 Datalink (ethernet, token ring, ...) 2->3 providing address resolution (ARP) ie. media access control (MAC) to IP translation layer 3 Network (IP,IPX,RIP,...) 3->4 providing routing layer 4 Transport provides error handling in connectin oriented delivery and handles connectionless delivery Conneciton Oriented(TCP,SPX) Connectionless (UDP)
What are the 7 layer of network?
It's called the OSI Model... it has 7 layers. 1) Physical Layer 2) Data Link Layer 3) Network Layer 4) Transport Layer 5) Session Layer 6) Presentation Layer 7) Application Layer
Which layer performs data compression?
Layer 6 - Presentation Layer
Which layer manages data-format information for networked communications?
presentation layer
Which OSI layer enables the receiving node to send an acknowledgement?
Transport Layer
According to the OSI model which layer performs parity checking and error checking?
Data Link layer does the parity error checking Thanks, Samaresh
Which layer manages the end to end control and error checking?
layer 4
What are the primary functions specified by all transport layer protocol?
Conversation Multiplexing Segmentation and Rassembly Error Checking
What is the middle layer of the OSI reference model?
Middle layer of osi model is Transport layer functions: 1.Segmentation of data 2.connection managment 3.flow control of data 4.Error checking
What is a fast but unreliable delivery protocol that operates on the Transport layer?
This would be UDP. The User Datagram Protocol. It has no error checking or correction or congestion measures.
What to do if the UDP receives datagrams that are not in sequence?
Since, there is no error checking in UDP. Datagrams will be passed to the next OSI layer without rearranging or in the order by the same which was received and it will not be dropped.
What layer of the OSI model performs error correction?
Layer 2 - The Data Link Layer Layer 2 of the OSI model provides error-detection capability
How do certificate covers protect important documents?
A certificate cover protects important documents by providing a protective layer around them. This may stop documents from accumulating dust or from spillages, for example.
What is the Difference between data link error control and transport layer error control in osi model?
Data link error control checks for error in each router and end-system, but transport layer error control checks for error only at the end-systems.
What layer is responsible for delivering data framer from one station to next without error?
layer 4 is responsible of error free data transmission
Why do you need another checking mechanism at the transport layer?

Why header and trailer is present in network layers?
HEADERS: It is a part of an information structure that precedes and identifies the information that follows,such as block of bytes in communication.TRAILERS:It is an information typically occupying several bytes ,at the tail end of a block of transmitted data which may contain a checksum or other error-checking data useful for confirming the accuracy and status of transmission.
