  WHAT IS ROUTER ?                    Router is a  network layer  Layer 3  device  of the OSI reference model   device that means it can connect multiple   computer   networks via wired or wireless connections. Network router can receive, analyze, perform the traffic directing functions and forwards data packet from one network to its destination node. A router is a device that forwards packets between networks by processing the routing   information   included in the packet.      Routers use logical and physical addressing to connect two or more logically separate networks . They accomplish this connection by organizing the large network into logical network segments or sub-networks. Each of these sub networks is given a logical address. This allows the networks to be separate but still access each other and exchange data when necessary. Data is grouped into...

Every user’s device needs at least IP address to join the network and connect to services. When computer first connects to local network with cable or WiFi SSID, first thing is to look for IP address, netmask, default gateway and DNS servers. Host connecting to network (cable or wireless) sends DHCP discover message to all hosts in Layer 2 segment (destination address is FF:FF:FF:FF:FF:FF). Frame with this  DISCOVER  message hits the DHCP Server.      2. After the DHCP Server receives discover message it suggests the IP addressing offering to the client host by unicast. This  OFFER  message contains: proposed IP address for client (here 192.168.1.10) subnet mask to identify the subnet space (here 255.255.255.0) IP of default gateway for subn...
