TCP is a robust protocol: Sequencing and error correction are ensured, but there is a penalty in overhead (for example, if
no re-sequencing or error correction is needed). UDP does not provide these services but is correspondingly simpler. Cite
specific situations in which the lightweight UDP protocol could be acceptable, that is, when error correction or sequencing

1) Classful & Classless routing

Classful routing : Routing Protocol that do not send subnet mask information when a route update is sent out. All devices in the network must use the same subnet mask

Eg : RIP V1

Classless routing : Routing that sends subnet mask information in the routing updates. Classless routing allows VLSM (Variable Length Subnet Masking)

Eg : RIP V2 , EIGRP , & OSPF.

2) Difference between RIP V1 & RIP V2.

RIP V1 : Distance Vector , Maximum Hop count of 15 , Classful , No Support for VLSM , No support for Discontigious networks.

RIP V2 : Distance Vector , Maximum Hop count of 15 , Classless , Supports VLSM networks , Supports Discontigious networks

3) Mulitcasting : Any Communication between a single sender and multiple receivers.

In Networking Multicast messages are sent to a defined subset of the network addresses.
