Protocol: A protocol is a set of rules that enables information to be sent and received. It is involved in the formatting and processing of the data available.  

Routed Protocol: Delivering application traffic by providing the information applicable,
routed protocols are used to identify our network paths.  

Packet: A packet, in simpler terms is basically a small portion of data that can be sent over a network. Individual packets contain information that helps routers to send the specific packages
to the correct destination along with the IP address of the sender and receiver.  

Router: A router is basically a device that connects and forwards packets of data between
various computer networks. The router utilises IP addresses of the specific packets to choose the best way to transfer them. It can connect multiple devices to the same Internet connection and perform various other actions relating to the particular network.  

Fault tolerant: Fault tolerant is basically multiple pathways that enable a particular system to continue operating in the rare event of a failure or disaster. It essentially allows the particular system to continue its intended usage, rather than failing completely. Here, it refers to the
efficient transmission of data even when certain parts of the network systems are down.  

TCP: TCP refers to The Transmission Control Protocol which is a transport protocol that is generally used on top of the IP address to ensure the accurate and reliable transmission of
packets. This involves mechanics to solve various issues that are awoken as a result of
packet-based messaging, corrupted packages and much more. TCP is very connection-oriented,
as it requires a connection between the client and server before data can be sent. 

Scalable: With regards to Routing, Scalability refers to the property that guarantees overall network performance despite the gradual increase of the size of the network. This basically
means that even though the network grows, it can still maintain the performance.
