Let us begin by learning about Google.GoogleGoogle represents the Global Organization of Oriented Group Language of Earth. It is a famous search engine defined in Internet-related services and products. Its main service areas are Online advertising technology, cloud computing, search engines, and software. It is a generally used search engine all over the world.Google has several applications like Google Docs, Adwords, Adsense, Youtube, Gmail, etc. Google Chrome is the most popular and worldwide used web browser in the current era. It is a cross-platform browser created and released in September 2008.Originally, it was launched particularly for Windows but next was ... Read More

HDLC (High-Level Data Link Control) is a bit-oriented protocol that is used for connection over the point-to-point and multipoint connection. This protocol executes the structure of ARQ (Automatic Repeat Request).The HDLC procedure is controlled by ISO. This is applicable for high-speed communication of a high amount of data, something the essential control process cannot provide.The HDLC process has been regulated and created on the SDLC. It can include characters, bit strings of the needed length can also be shared through this process. The unit of data communication is referred to as a frame.A mode in HDLC is the realigning between ... Read More

Touch Screen is an essential source of input or output device generally layered on top of a computer visual device. A user provides the input or controls the data processing through individual or multi-touch gestures by touching the screen. It allows the user to connect directly with what is shown, instead of using any intermediate device.Touch Screens have made several devices so easier to use. It is generally used in ATMs as the resistive touch screen system. It includes two electrically conductive layers, one of which is resistant and the new one is a conductive layer. These two layers are ... Read More

Data Link Layer is the second layer in the OSI reference model. It represents creating a shared transmission medium and frequent transmission of the data frame in a computer transmission setting.It obtains a natural flow of items for the physical layer at the sender device. The primary stream of data is generated using different technologies like cable, DSL, wireless, optical fibre, etc.Protocols define a collection of rules or conventions for executing a definite function. It is a collection of the requirements that can manage the data link layer. The fundamental goals of computer broadcasting in a system environment are to ... Read More

Li-Fi represents light-fidelity. It is a networking technology that uses a clear spectrum instead of radio waves. The technology uses a standard LED light bulb to share information. The LED bulbs are appropriated with a chip that inflicts the light for optical data transmission which is accepted by photoreceptors.A LiFi network uses the light from LED lamps to send information to a device, including a computer or tablet. The device has a receiver to select light signals and an address to send light signals back to the lamp using infrared light.The light from the LED lamps transforms intensity lots of ... Read More

PBX represents private branch exchange. It is a private mobile network used within an enterprise. It is a business-oriented phone system created to supply effective voice communications among the users of an organization.It is performing as the phone company’s central office within an organization, a PBX facilitates as the exchange point and point for routing calls.PBX enables users to generate their own telephone network inside a company or organisation. With this system, employees can connect internally for collaboration objectives and externally, with users, shareholders, and several contacts using channels such as VoIP or ISDN.Every device linked to the PBX, from ...

Let us understand what the Interior Gateway Routing Protocol (IGRP) is.IGRPIGRP represents the Interior Gateway Routing Protocol. It is a protocol that was generally developed for routing by Cisco Systems in the 1980s. The objective of IGRP is to develop IGRP to support a routing protocol to be used with the autonomous system architectures.IGRP uses a sequence (vector) of metrics. Internetwork delay, bandwidth, dependability, and load are all part of the routing decision. The network controller can set the weighting element for each of these metrics. IGRP uses the authority-set or the default weightings to necessarily calculate optimal routes.IGRP supports ... Read More

MITM stands for a man-in-the-middle attack. It is a cyber-attack where an attacker transmits and probably alters the connection between two parties who consider they are communicating precisely. This enables the attacker to transmit communication, investigate, and even change what each party is saying.In MITM, it can define a type of cyberattack where an intruder covertly taps transmissions connecting two entities to check or develop traffic therebetween. Malicious ones can use MitM attacks to seize passwords or multiple sensitive data, snoop on the prey, disrupt links, or distort content.Types of MITMThe types of MITM are as follows −Rogue Access PointDevices ...

MANET stands for Mobile Ad-Hoc Network. It is an infrastructure-less collection of mobile nodes that can arbitrarily change their geographic locations such that these networks have dynamic topologies which are composed of bandwidth-constrained wireless links.MANET nodes are supplied with wireless transmitters and receivers. At a given time based on the nodes positions and their transmitter and receiver coverage designs and transmission power levels, wireless connectivity in the structure of a random, multi-hop graph or ad-hoc web exists between the nodes. The current applications of MANETs are in defense services, emergency search, and rescue services, meetings, and conventions, and other scenarios ... Read More

IOT represents the Internet of Things. It is a network of physical objects or people known as "things" that are installed with applications, electronics, networks, and sensors that enable these objects to collect and exchange information. The objective of IOT is to extend to web connectivity from standard devices such as computers, mobile, tablets to associatively dumb devices like a toaster.Components of IOTThere are various components of IOT which are as follows −Sensors/DevicesSensors or devices are a component that supports us to collect live information from the surrounding environment. All this information can have several levels of complexities. It can ... Read More
