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 switch or a bridge rely on MAC addressing.
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..
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.
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.

Packets relate to the sending and receiving of batches of data between two devices.
The loss of data packets during transmission.
As a packet traverses different networks, the source IP address will always stay the same as the original sending devices IP address unless NAT (Network Address Translation) is involved somewhere along the line.
They check packets by source address They check packets by destination address
To transmit packets of private subnet through public internet
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
Packets per second - In networking, the amount of packets a device can process per second. Packets per second (pps) is a measure of throughput for network devices such as bridges, routers, and switches. It's a reliable measurement only if all packet sizes are the same. Vendors will often rate their equipment based on pps, but make sure comparisons are made using the same packet sizes.
A router is a computer networking devices, that forwards the data packets along the network. there two types of routers Wireless broadband routers and wired router, these both are look much the same.
