ROUTER Settings Router Definition and how it work

• Router Definition and how it work .
  

 

Router Definition: Router is a hardware device that 
lets forward or move to another network by analyzing the receipt of 
incoming network packets.If we talk about the router in 
the Internet case, then 
the router analyzes the 
packets and detects 
the next network point and forwards 
the packet to the destination.

Router also performs packets in other network interfaces, drops, or another network relayed operation. If the Routers are defined in a simple language, it can be said that it is a small electronic device that connects multiple computer networks with the help of wired or wireless connections, and the packet router receives them. Analyze and forward / pass in another network.

• How it works.

• 
  When a packet comes with the router, after determining 
  the address and internal routing table of the router destination network, 
  it decides which port or network to forward to the packet.
  to forward to the packet.
  The Router is a Layer 3 network device and operates on the network layer of the OSI model.
  The memory of the Router is an embedded operating system (O / S) store,
   which takes very little storage space compared 
  to the other OS. Popular router 
  operating systems - Cisco Inter network Operating System (IOS) and DD-WRT
  
  Actually Routing is the process of managing data flow between network segments 
  and between hosts or routers. To manage this routing, the router manages a table 
  that has the information store of the other routers of the network.
