What else can I help you with?
A router that uses the RIP routing protocol has an entry for a network in the routing table. It then receives an update with another entry for the same destination network but with a lower hop count.?
it will append the update information to the routing table
How is data passed in packets?
The details vary enormously from protocol to protocol, but the basics are the same for all of them. A stream of data is split into packets, the packet has a header which contains (amongst other things) the destination for the packet. The network uses the destination address to deliver the network to the correct destination.
Exterior routing protocol example?
BGP border gateway protocol is the most commoly use exterior gateway protocol. EGP are used by ISP's and are being routed from a private network to the internet and to its destination private network.
In an Internet Protocol Version 4 environments IPv4 what information is used by the router to forward data packets from one interface of a router to another?
destination network address
What protocol is used to send a destination network an unknown message back to originating hosts?
The protocol used to send an unknown message back to originating hosts is Internet Control Message Protocol (ICMP). Specifically, ICMP can send messages such as "Destination Unreachable," which informs the sender that a packet could not reach its intended destination. This helps in diagnosing network issues and improving communication reliability.
What is one function of a network protocol?
To ensure data delivery.to ensure that data arrives at its destination in the proper sequence
What network layer protocol does the traceroute utility use to obtain its information about paths between a source and destination?
ICMP
Forms of network access protocol?
n/y access protocol means say in arp process when an ip has a data and it needs to sent it, it must inform network access protocol such as ethernet and token ring of the destination hardware add on the local n/w.
Which routing protocol uses hop count as the metric?
RIP (Routing Information Protocol) uses hop count as the metric. It measures the distance to a destination network based on the number of routers (hops) that a packet has to traverse to reach the destination.
Which protocol is responsible for showing the data the way to the destination?
The protocol responsible for directing data to its destination is the Internet Protocol (IP). IP handles addressing and routing, ensuring that packets of data are sent from the source to the appropriate destination across networks. It operates at the network layer of the OSI model and works in conjunction with other protocols, such as TCP or UDP, to facilitate reliable communication.
What is a communication protocol?
a way for transmitting data form one computer to the another across a network is called as communication protocol
What protocol conserves network bandwidth by detecting changes in files and transmitting only the modified data to the destination?
Server Message Block
