Let us understand the concepts of QR Code and Fastag.QR CodesQR code is called as "Quick Response" and it allows us to encode or store over 4500 characters in a two-dimensional bar code. These codes are the "square barcodes" that are initially developed and used in Japan.The main aim of the QR code is to store the information in such a way that the machine (scanner) can be able to read the data present in the code.Given below is the Sample QR code image −As we can see above all QR codes are made of black dots and white spaces ...

To send the data from one device to another device there should be a connection. The connection can be established to transfer data between the devices can be done in two ways and they are as follows −Connection-Oriented ServiceConnectionless ServicesNow let us discuss the Connection less services.Connection less ServicesIn connectionless the data is transferred in one direction from source to destination without checking that destination is still there or not or if it is prepared to accept the message. Authentication is not needed in this. Example of Connectionless service is UDP (User Datagram Protocol) protocol.Connectionless service is a service that ... Read More

Let us learn the concepts of Routing Information Protocol (RIP) and Border Gateway Protocol (BGP).Routing information protocol (RIP)This protocol employs the port 520 and the routers utilize it for sharing the information over a network and avert the routing loops.It sustains the routing table for elucidating the ultimate effective manner in order to route the data.Often permits the data to result over an immersive speed in lesser duration.It determines the best route by employing the hop count.It permits the hop count around 15.If it exceeds more than 15 then the network elucidates a network is taken as unreachable.A path containing ...
