What protocol conserves network bandwidth by detecting changes in files and transmitting only the modified data to the destination?
Server Message Block
Does Simple Network Management Protocol have any types of message?
i want the answer for this question (i.e) is there any message types found in simple network management protocol
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.
Is a Network layer protocol that reports on the success or failure of data delivery?
ICMP (Internet Control Message Protocol)
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.
What network layer protocol does the traceroute utility use to obtain its information about paths between a source and destination?
ICMP
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 are true statements about routes and their use?
--> If the destination network is directly connected, the router forwards the packet to the destination host. --> If no route exists for the destination network and a default route is present, the packet is forwarded to the next-hop router. --> If the originating host has a default gateway configured, the packet for a remote network can be forwarded using that route.
What network layer protocol layer does the traceroute utility use to obtain its information about paths between a source and destonation?
It uses ICMP protocol - Internet Control Message Protocol
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.
What is the use of ping in networking?
Ping is a computer network administration utility used to test the reachability of a host on an Internet Protocol (IP) network and to measure the round-trip time for messages sent from the originating host to a destination computer. Ping is used to identify if there is an internet connection and how fast it is.
What is the TTL - Time to Live and Why is it required?
TTL is a value in data packet of Internet Protocol. It communicates to the network router whether or not the packet should be in the network for too long or discarded. Usually, data packets might not be transmitted to their intended destination within a stipulated period of time. The TTL value is set by a system default value which is an 8-bit binary digit field in the header of the packet. The purpose of TTL is, it would specify certain time limit in seconds, for transmitting the packet header. When the time is exhausted, the packet would be discarded. Each router receives the subtracts count, when the packet is discarded, and when it becomes zero, the router detects the discarded packets and sends a message, Internet Control Message Protocol message back to the originating host.
