Routing


The general meaning of Routing is "the scheduling of the route or itinerary of people, freight, etc."
In the case of networks Routing is a process by which the router finds the best path for a data packet in between source and destination.
Note: there are two types of protocols 
Routed Protocol and Routing Protocol.
Routed protocol: Routed protocol is a protocol that helps to travel data packets in the network.
Like: Ip,  IpX, Apple talk.
Routing protocol: Routing protocol is a protocol that helps to find the best path between source and destination.
Again Routing protocol subdivided into two types:
Static Routing
Dynamic Routing 
Static Routing: In this type of routing we are selecting a manual path for the destination. That type of routing is the most trusted routing.
Dynamic Routing: In this type of routing router decides what is the best path for the destination base on metrics. That type of routing considers as partially untrusted routing.
Pros:
Static routing is trusted.
Dynamic routing easy to use and configure.
Cons:
Static routing very complex to configure for a big network.
Dynamic routing is an untrusted routing.

Nowadays everyone uses the internet, which helps to connect the world. Everyone is familiar with a few common terminologies like IP address, Subnet masks, default gateway, DNS server, or I can say the picture which is down below what is the significance of this window? The simple answer is this all terminology helps to communicate with the outside world. If I asked you how that might be difficult for some guys. Today in this blog I will discuss this terminology believe me guys networking is as easy as to look dangerous. IP address: It is an address that gives a unique identity to our device in the network. Subnet mask: It is used to define network size and how many, host machines are present in a network. Default Gateway: It is a gate where all traffic traveled from one network to another network. Technically It is an interface where LAN is connected to the router. DNS servers: DNS stands for Domain namespace /system. It provides IP to name mapping. In a production networ

A network is a communication media between two communicative devices, with the help of network devices, which are able to share information with each other. In communication engineering, the transmission media also are known as Channel. By there own characteristic the network has split into two-part - 1)Wire Network. 2)Wireless Network . Wire Network: In this type of network the communication media is made by wire.  This is also known as guided media. Examples: Broadband Connection, codeless telephony. Advantages: 1)Less lossy communication. 2)Speed is much higher than wireless media. Disadvantages: 1)Costly. 2)Bulky. Wireless Network: Computer networks that are not connected with a cable this is known as a wireless network. This type of network is also known as unguided media. Examples: Mobile Phone communication, WiFi. Advantages: 1)Less costly 2)Increase mobility. Disadvantages: 1)lossy communication.
