HAN represents the Home Area Network. It is a network that is set up and managed inside a small border, frequently a house or small office/home office (SOHO). It allows the connection and sharing of resources such as the Internet among computers, mobile and some devices over a network connection.The main hub of a HAN is the router. In some cases, the router is linked to a modem, which connects with an ISP. The modem supports an Internet connection to the router, which consecutively supports Internet access to all connected devices inside the home.In larger homes, a HAN can involve ... 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
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

Categorical data are discrete data. Categorical attributes have a fixed number of distinct values, with no sequencing among the values involving geographic area, job category, and item type. There are various methods for the generation of concept hierarchies for categorical data are as follows −Specification of a partial ordering of attributes explicitly at the schema level by users or experts − Concept hierarchies for categorical attributes or dimensions generally contain a group of attributes. A user or professional can simply represent a concept hierarchy by defining a partial or total ordering of the attributes at the schema level.For instance, a ... Read More
