To begin with, let us learn the concepts of firewall and proxy server.FirewallIt is used to provide security, mostly from external networks such as the Internet. It is the combination of software and hardware to allow, deny, monitor, and block any and all data transmissions occurring from a specified internal network.Firewalls evaluate, allow, or deny network traffic based on certain predefined rules set-up based on IP addresses or its range, port numbers, protocols, and few other factors. It provides good traffic management.Firewalls defend against external threats refusing or denying unauthorized requests, transmissions, and connections to the router, network, application software, ...

Let us begin by understanding the concepts of advanced message queuing protocol (AMQP) and HyperText Transfer Protocol (HTTP)AMQPAdvanced message queuing protocol (AMQP) is a message protocol that deals with publishers and consumers. The publishers produce the message whereas the consumer picks the message and processes it.Given below is the pictorial representation of AMQP −This protocol is used in client-server messaging and in IOT device management. It allows the messages to be passed between applications.AMQP is a new standard design to meet financial institutions and it enables the interoperation, sharing which allows business to work together in a wide infrastructure.AMQP secure ...

Let us understand the concepts of QR code and Near Field Communication (NFC).QR CodesQR code is called "Quick Response", it allows us to encode or store over 4500 characters in a two-dimensional bar code.These codes are the "square barcodes" that were 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.Uses of QR codesQR codes can be used for storing data like −Simple textPhone numbersOnline conferences via zoom appOnline one time passwords(OTP)Online accounts authentication ...

The full form of WWW is World Wide Web which is the internet that we are using nowadays. Tim Berner’s lee, a British scientist in CERN, invented the World Wide Web (WWW) in 1989.Originally it was meant to meet the demand for automatic information sharing between scientists of universities and institutions around the world.Later on the commercial potential in web makes the growth of web in an exponential paced manner. It is kind of a store where all the websites and documents are stored and we access those using different websites and their domains. The resources are transferred to us ... Read More
The Full form of AURP is “AppleTalk Update-based Routing Protocol”. AppleTalk tunnelling permits a corporation chairman to associate a minimum of two local internets through an unfamiliar organization framework to shape a huge wide region organization (WAN).ExampleAn AppleTalk WAN may comprise of a minimum of two local AppleTalk internets associated through a tunnel supporting a TCP/IP web. In such an AppleTalk WAN, local internets use AppleTalk protocols, while the unfamiliar organization framework utilizes an alternate protocol family. A tunnel is often either an unfamiliar organization framework or a highlight point interface.There are two kinds of tunnels, double endpoint tunnels and ... Read More
Let us understand the concepts of Fastag, Bar code, QR code and Near Field Communication (NFC).FastagFASTag is an electronic scanner system used for toll collection in India, which is operated by the National Highway Authority of India. It is based on radio frequency identification (RFID) technology. FASTag is fixed on the windscreen of vehicles. FASTags does not have any expiry date. They can be recharged at any time.Working of FASTag systemVehicles with FASTag enabled do not have to stop at toll gates where charges are deducted from the prepaid or bank account when the vehicle is moving. The drivers do ... Read More

Near-me Area Network (NAN) may be a sensible communication network centred around communication between remote devices, for instance, Smartphones and private Digital Assistants then on inside a closeness area. This Near-me Area network is worked over existing actual network foundations.In basic during a Local Area Network (LAN) all of the associated devices are within the same network segment yet if there should arise an event of Near-me Area Network the associated devices over NAN could be utilizing diverse network frameworks.For instance, consider two smartphone clients who are geologically close however utilizing network administrations from various mobile transporters.Regardless of whether the ...
