If we are sending a file in one go and if some error occurred in between the file transfer then the complete file has to be resend which wastes the bandwidth so to prevent this, the file to send is divided in to smaller unit which we call packet, and then send packets 1 by one so that if a packet is lost then we need to send only that particular packet not the complete file.
The loss of data packets during transmission.
Filtering is the act of deciding which data packets are allowed to be sent and which packets should not be sent.Packets that are not sent are said to be filtered.Filtering decisions can be made by any device that routes, generates, or receives packets, but generally packets are filtered by firewalls.HTH,Gdunge
The router pattern bit in networking devices is used to determine the path that data packets will take when traveling between different networks. It helps the router make decisions on how to forward the packets to their intended destination.
The localhost address is designed to verify that the software for networking has been installed and is operating correctly. It does not pass any packets to the network.
A MAC address is used as a unique identifier that is assigned to network interfaces. Two networking devices that transmit packets based on MAC addresses are switches and bridges.
A networking hub is a device that relays data communication. It sends data packets to all devices that are within a network, regardless of any MAC addresses it contained.
PDV stands for packet delay variation. It is a term used in computer networking which is the difference in the end-to-end one-way delay between selected packets in any ignored lost packets.

A router is a networking device that forwards data on a network.
Internetworking devices which means its efficient and performance is up to the mark. But in networking devices there is a lot of problems when we are sending the packets from one computer to another computer.So its difficult to work with networking devices compare to interconnecting devices. Cost is moderately high in this..
In networking there is a source and a destination and when both of them communicates there is transfer of packets. There are many routes that can be taken to deliever packet from source to destination but out of all the routes the best route is to be selected, which is done by router and this process is called as routing.
In the computer and networking industry, a traceroute is used to display the path and transitioning delays for packets across an IP network. It is used on a number of systems.
