When you send information over the internet, it goes through many intermediate places, or "hops" - 15 to 20 is fairly typical. To visualize this, give the following command in a command window (in Windows); that will show through which intermediate hops information travels:
tracert www.Google.com
Or some other Web address.
Each "hop" is a router (or similar equipment), which must decide where to send the packet next. Basically, a router consults its routing tables, which say, for example, "any packet to a destination address that begins with '192.53.' should be sent to that-and-that next-hop-address."
Internet routing consists of the whole process of maintaining, and using, those routing tables.

routing is the gateway whereas the switching is where the internet cables are plugged.

CIDR (Classless Inter-Domain Routing, sometimes known as supernetting) is a way to allocate and specify the Internet addresses used in inter-domain routing more flexibly than with the original system of Internet Protocol (IP) address classes. As a result, the number of available Internet addresses has been greatly increased. CIDR is now the routing system used by virtually all gateway hosts on the Internet's backbone network. The Internet's regulating authorities now expect every Internet service provider (ISP) to use it for routing.
The routing protocol computers use to communicate over internet is as under :- TCP/IP (Transmission Control Protocol/Internet Protocol). The above protocol is used by computers to communicate over internet throughout the world.
No, ICMP is not a routing protocol. ICMP (Internet Control Message Protocol) is used by the Internet Protocol suite (IP) to send error and status messages. It is mainly used for diagnostics. Ping and traceroute are two tools that use ICMP. ICPM is used by routing protocols, for routing advertisements and router discovery.
IP (Internet Protocol)

BGP is always used as the routing protocol of choice between ISPs (external BGP) but also as the core routing protocol within large ISP networks (internal BGP).
It allows a large organization to more easily keep track of routing and network requirements, especially with an ISP (Internet Service Provider). The organizational benefits give a clearly defined routing policy for the internet.
Open Shortest Path First (OSPF) is a type of routing protocol known as an interior gateway protocol or an interior routing protocol. The routers in an internet are responsible for receiving and forwarding packets through the interconnected set of networks. Each router makes routing decisions based on knowledge of the topology and traffic/delay conditions of the internet. The routing protocol between routers is used to exchange topology and traffic delay information. An interior routing protocol is used within a portion of the internet called an autonomous system, which simply means a connected set of routers that are managed by a single organization. OSPF is the most commonly used interior routing protocol.
The acronym EIGRP stands for Enhanced Internet Gateway Routing Protocol. The protocol is loosely based on the Interior Gateway Routing Protocol invented by Cisco.
