Why do you think we need additional checking method at the transport layer if the data connection layer can detect mistakes between hops?
Step by step
Solved in 2 steps
- Why do you believe we need additional checking method at the transport layer if the data connection layer can identify mistakes between hops?Given that the data connection layer is capable of detecting mistakes between hops, why do you believe that we need an additional checking mechanism at the transport layer?Why, in your opinion, do we need more checking techniques at the transport layer when the data connection layer is capable of detecting errors between hops?
- In computer programming, the duration of a variable's refers to the amount of time that the variable is present in memory while the program is running. Close the chasm.andInternet model: how does data go from one layer to another?Why do you believe we need a second method for verifying at the transport layer if the data connection layer can identify problems in between hops?Discuss the role of hubs and repeaters in the OSI model. How do they operate at the physical layer, and what are their limitations?Explain the role of a switch in the context of the OSI model. How does it operate at the data link layer (Layer 2)?
- Discuss the functions of a bridge (data link layer) in the OSI model and how it differs from a router.Describe the function of a router in the OSI model. Which layer(s) does it primarily work at, and how does it enable data exchange between different networks?What is the difference between the OSI levels if routers occupy many layers?
- How does a router function in the OSI model, and at which OSI layers does it primarily operate? Discuss the role of routing tables in making forwarding decisions.Explain the role of the BFD (Bidirectional Forwarding Detection) protocol in network reliability. How does it detect link failures and enable fast routing convergence?What layer 2 protocol issues have been found on the router? What effects does this discovery have? Why does the serial interface subnet change and the ICMP request still function in a PPP encapsulated router?
