There are two types of communications. connection oriented where there is direct line of communication between the sender and the receiver like a telephone n/w. The other is the connectionless communication. This is how most of the internet is arranged. The sender sends the packet to the destination and the packet must find it's way through the network. Routers are intermediate nodes the packet must pass through to reach it's destination. These nodes can be pc's, servers etc. Routers have to check whether the packet they just received is meant for them or for someone else. If it is for someone else then they run special algorithms called routing algos which compute which will be the shortest path for the packet to reach it's destination, and then they they send the packet in that direction. There can be several other functionalities that one can load into a router eg. firewall settings for application level or circuit level gateway etc.
The term "router" refers to either a woodworking tool or a computer networking device. In carpentry, a router is used to hollow out a section of wood whilst in computing, a router connects two, or more computer networks together.
· Routing is the process of sending information to a specific destination such as another computer or system.
· The router is a hardware device that performs such transmission and it achieved using different routing protocol.
· Routing protocol goal is Increased network security.
The basic purose of routing table is that each packet in a network is going to follow
the path and indicate that where the packet is going.
And that's why every router has a routig table.
To protect PC's in network from hackers by controling how the router deals with PC's outside the network communications to PC's in the network. May involve "ping"- port forwarding and port triggering-also how the pc's communicate and share in the network ex- files; printing etc. Increased network security is the goal.

It allows a router to share information about known networks with other routers.
RIP stands for routing information protocol. It is an intra domain routing protocol.
Dynamically, as related to a routing protocol is a type of networking technique whereby the routing protocol creates, updates and maintains the dynamic routing table.
RIP is a routing protocol - a protocol (set of rules) that allows a router to exchange information, with other routers, about existing routes.
Routing Information Protocol (RIP) and Interior Gateway Routing Protocol (IGRP) are two very popular Distance Vector routing protocols
A classless routing protocol can route between subnets
Routing Information Protocol (RIP)
IGRP - Interior Gateway Routing Protocol EIGRP- Enhanced Interior Gateway Routing Protocol
A routing protocol is a protocol that routers use to tell each other about available routes. Some of the routing protocols include RIP, EIGRP, OSPF, IS-IS, BGP.

RTMP- Routing Table Maintenance Protocol.
Each router independently determines the route to each network. After the inital LSP flooding, they generally require less bandwidth to communicate changes in a topology.
A routing protocol is a formula that specifies how routers are communicating to each others. Types of routing protocols include Interior Gateway Protocol, Distance vector protocol and Classful or classless protocol. Routing protocols are required to determine the appropriate paths for data transmission.
